Selection criteria: wood or metal
For many car enthusiasts, the garage is a second home, so they approach its arrangement with due attention. A particularly important point is the purchase of a workbench; the selection criterion may be the purpose for which it is intended. In most cases, such equipment is installed to perform the following work:
For regular inspection and maintenance
car.
For small plumbing work
, minor repairs, correction of defects associated with the maintenance of the house and garden area.
If plumbing or carpentry is part of your hobby
.
The first question that arises when choosing is the material of manufacture. There are wooden (most often homemade) and metal workbenches offered by various manufacturers, both domestic and foreign.
Workplace for the soul
Wooden workbenches
A wooden workbench for the garage, made entirely or partially from wood, is suitable for periodic and short-term work with simple parts; it is not well suited for machining complex metal components. The frame of such models is made of strong wood (beech or oak) and secured with self-tapping screws. The stability of the table is ensured by additional spacers, transverse or x-shaped. Wooden models are usually equipped with shelves or drawers for storage. The wooden tabletop is trimmed with metal along the edge.
A common model is a design of two massive cabinets connected by a tabletop. This option looks quite practical, since it solves most of the problems associated with the placement of tools. Despite the relative cheapness and good (albeit somewhat limited) functionality, many believe that a workbench in a wooden garage has significant disadvantages:
The wooden bench is not designed for heavy loads

Metal workbenches
To assemble a functional metal bench, you will need special equipment and skills in working with metal (the fragments are connected by welding). Metal models, assembled in workshop conditions, have a durable construction and modern design. Despite the higher price due to the cost of metal and a more complex assembly process, metal equipment has many advantages, including:
Long service life
. Stainless steel models boast an impeccable service life of 50 years.
Large selection of models
and their configurations. Manufacturers offer both universal and highly specialized options.
Multifunctionality
. You can perform any type of work, including turning, cutting, grinding.
Mobility and compactness
. Many models can be disassembled (in whole or in part), and, if necessary, new tools (vises, clamps) can be added.
Light weight
while maintaining strength. The tabletop is resistant to deformation and damage (scratches).
Minimal care
. The design is characterized by increased resistance to corrosion processes and does not require painting. Cleaning metal dust and shavings from the surface of the countertop does not take much time.
Workbench: this is the main element of the woodworker's workshop
In any workshop where they work with wood, there is always a carpentry workbench. Regardless of how the material is processed (manually or using a power tool), the presence of this element allows not only to properly organize the workspace, but also to make it more convenient and comfortable. All this ultimately affects the result. In such conditions, the productivity of the master and the quality of his work increase.
Any carpenter cannot do his work without a workbench.
A workbench is a work table that is used for processing wooden products manually or mechanically. Its design and ergonomic capabilities are designed in such a way that it is convenient for the master to fix parts in different positions to perform various tasks.
The workbench allows you to perform the following operations:
- assembly of wooden structures;
- production of wood parts;
- processing of workpieces with varnishing compounds and other means.
A carpenter's workbench is a table on which a craftsman processes wood products.
On a note! A traditional carpenter's workbench is designed for working with lumber whose length does not exceed 3-3.5 m. To work with longer workpieces, you will have to use a carpenter's workbench.
Workbench requirements
A master professionally engaged in metalworking does his work only in a specially equipped place. Comfortable conditions and safety will be ensured only if there is a workbench. And, according to practicing experts, it must meet a number of requirements:
- large margin of safety and reliability. It is important that you can work in intensive mode or with large, heavy workpieces;
- maximum functionality and thoughtful ergonomics. A well-organized workplace, where everything necessary for work is always at hand, is a prerequisite for production efficiency;
- sustainability. When you have to work with heavy components, this requirement is mandatory for safety. Without a stable table it is impossible to ensure high accuracy of work;
- immunity to aggressive compounds and other influences. A bench made from high-quality materials lasts for several decades.
Construction of a carpentry workbench: design features
The simplest carpentry workbench consists of two elements: a workbench board (tabletop) and a workbench (a frame that performs a load-bearing function). A traditional workbench must be equipped with a vice. Depending on their placement, they can be front or end. Using a vice, wooden blanks are fixed in the required position.
Construction of a carpentry workbench: 1 – front clamp; 2 – rear clamp; 3 – screw; 4 – twists; 5 – tray; 6 – emphasis; 7 – sockets for wedges; 8 – wedges; 9 – front legs; 10 – hind legs; 11 – connections (2 pcs.); 12 – wedges (4 pcs.).
There are holes in the cover of the workshop table, as well as in the jaws of the vice, made of wood. They are used to install stops and clamps, which can have different heights and cross-sectional sizes.
Before work, the stops are set in a certain configuration so that the part can be placed between them in the required position. After the workpiece is installed, it is pressed using a screw mechanism that is equipped with a vice. This design allows you to securely fix the wooden part in a horizontal position.
The vice can be used to work with workpieces of different thicknesses. Specially for this purpose, stops of different heights are provided. The size of this element is selected so that during the processing of the part it does not protrude beyond the edge and does not interfere with the master.
The required components of the simplest workbench are a table top and a supporting frame.
Purpose
The bench is used for processing parts made of metals and alloys. The design is designed to perform a wide range of operations:
- carving;
- engraving;
- trimming parts;
- riveting;
- drilling holes;
- bending and cutting;
- assembly of mechanisms.
To work on a workbench, special tools are required. One of the most necessary devices is a vice. Using a tool mounted on a table, parts or workpieces are fixed.
Materials for making the frame and cover of a carpentry table
In the process of processing wooden workpieces, the working surface is subjected to serious loads, so increased demands are placed on it. Regardless of whether a regular or folding carpentry workbench is made with your own hands, its structure must be strong and rigid.
The workbench must be made of rigid and durable materials.
A high-quality frame must withstand all types of loads:
- Static. They occur under the influence of heavy weight if a massive workpiece is processed on the table.
- Dynamic. They are a side effect of processes such as drilling, sawing, impacts, etc.
The strength characteristics of the frame depend on factors such as the reliability of the fastening elements (nails, bolts, nuts, screws) and the type of material from which it is made. The underframe is made from softwood, such as pine. Although linden or maple are also suitable for these purposes.
Most often, the workbench top is made of wood.
The workbench tabletop is made of wood with a high strength index:
- beech;
- oak;
- maple;
- ash, etc.
To create a carpentry table cover with your own hands, experts recommend using a glued board. In this case, you will not have to spend a lot of time and effort on adjusting the wood. A complete blank in the form of a laminated board will eliminate the need to cut the material, process its edge part, and then glue and level it. The finished shield will cost a little more, but it's worth it.
On a note! When working with wooden workpieces, you can accidentally damage the cover with a power tool. To prevent this, additional flooring can be made for the workbench top made of plywood or fiberboard. It is cut according to the shape and dimensions of the lid. It is better if the protective flooring is made together with the workbench.
The frame of a carpentry workbench is made of wood, less often of metal.
Material selection
The material is wood, steel, or a combination. In the composite version, the support frame is made of hard rock. For this they take oak, birch, plane tree, maple, acacia, and apple tree. It is not recommended to take spruce, fir, aspen, linden, chestnut.
Wooden posts and longitudinal elements can be fastened with iron corners or profile pipes for stability and reliability. There are single spacers or x-shaped structures. Screws and bolts are used for fixation. The iron walls of the bedside tables are equipped with drawers with sides, and shelves are made of thick OSB panels.
Compliance with assembly technology helps to increase the service life, despite the materials chosen for the manufacture of the desktop.
Choosing between wood and metal
Wood for making a workbench must be treated with antiseptics.
Wooden workbenches are often made with two pedestals. Two storage compartments serve as supports for the connecting tabletop.
This manufacturing option is cheap, but has some disadvantages:
- You can’t make great efforts;
- significant loads shorten the service life.
Wood requires preliminary and regular treatment with antiseptics and moisture impregnations. The surface gradually deteriorates from aggressive components, for example, car oil, gasoline drops.
Steel workbenches allow you to perform various types of work and can withstand heavy loads. Strength is ensured by metal supports, beams, and frame struts. A tabletop with a metal or galvanized coating does not deform from the action of aggressive substances. Wood and iron dust is quickly removed from the coating.
Main types of workbenches: photos of structures and vices for various purposes
Drawings of tables that can be found on the Internet are presented in a huge variety. To choose the best option for creating a workbench at home, it is better to decide in advance on the type of structure and its configuration. There are several types of tables used for working with wood.
The simplest design to manufacture is a stationary type workbench. To create it you will need a minimum set of tools and a little patience. Such structures are mainly used for processing large-sized wooden workpieces.
Carpentry workbenches differ in size and type of construction.
Folding carpentry workbenches have a more complex structure. These products are quite compact. Their weight does not exceed 30 kg. Such structures are considered mobile and, if desired, they can be easily moved from one place to another. In folding workbenches, the lower support part can be made of metal. This is done in order to increase the stability of the structure. Mobile tables are designed for working with small wooden workpieces.
Carpentry workbenches can also be composite. In this case, all structural elements are fixed using bolted connections. The advantage of such a table is that all its components are interchangeable. On the other hand, the drawings of composite type carpentry workbenches are quite complex, as is the technology for their manufacture. Only an experienced master can cope with this task.
Workbench vices come in universal, special, manual and chair types.
Before you start creating a workbench, you need to choose a suitable vice option. In this case, the specifics of future work must be taken into account.
There are several types of vices for a carpentry workbench:
- Chairs - these devices are used extremely rarely, since they are designed to perform heavy work.
- Universal – designed for working with small workpieces. Bolts are used to secure this fastener to the workbench cover.
- Special - allow you to adjust the position of the workpiece both vertically and horizontally, which greatly simplifies the work of the master.
- Manual - there are instrumental, rotary and non-rotary.
On a note! In non-rotary and rotary manual type vices, the width of the jaws is 8 cm.

Equipment and organization of a mechanic's workplace
General requirements
A mechanic's workplace at home can be organized in different ways. However, for convenience and greater efficiency, some basic rules should be followed.
In order to save movements and eliminate unnecessary searches, items in the workplace are divided into items of permanent and temporary use; Permanent storage and location areas are allocated for both.
If possible, objects at the workplace are placed in such a way as to avoid turning and especially bending of the body during work, as well as transferring objects from one hand to another.
Tools and devices during work should be placed on the workbench in the following order: everything that is taken with the left hand should be placed on the left side of the workbench, everything that is taken with the right hand should be located on the right side of the workbench. Tools and devices that the mechanic uses more often should be placed closer, and, conversely, those that are used less often should be placed further away. This arrangement must be permanent so that the mechanic can take the necessary tool, device or workpiece during work without spending unnecessary time finding them.
The tool should be stored in the drawers of the workbench in such an order that the cutting tools - files, taps, drills, etc. - do not deteriorate, and the measuring tools - squares, calipers, micrometers, etc. - do not deteriorate from nicks, scratches and impacts . To do this, transverse shelves 100–150 mm wide are made in the pull-out tool box of a mechanic’s workbench. Each cell should be intended for one type of tool. In one of the tool boxes of the workbench, along its sides, 3-4 stepped strips are nailed onto which files are placed; in this case, large files are placed on the lower steps, and small ones - on the upper ones.
The bottom of the box is divided into several cells for storing drills, reamers, taps and dies. The rest of the box area should be used to store coarser tools, such as hammers, chisels, crosscutters, etc.
Measuring instruments are stored in special cases or wooden boxes.
After finishing work, used tools and devices are cleaned of dirt and oil and wiped. Files must be cleaned of metal filings and dirt with a wire brush and wiped with a clean rag or napkin. The working parts of the cutting and measuring tools should be lubricated with a thin layer of Vaseline. The surface of the workbench is cleaned with a brush from chips and debris.
The workplace should have good individual lighting. The light should fall on the object being processed, and not on the face of the worker. It is desirable that the light be diffused and not create glare that interferes with work.
Mechanic's workbench
To perform manual work, most workplaces are equipped with a mechanic's workbench, on which a vice is installed and the tools, devices, and materials necessary for the work are laid out.
The workbench (Fig. 1) is a special table on which metalwork work is performed. It must be strong and stable. The frame of the workbench is of welded construction made of cast iron or steel pipes, steel profile (angle). The cover (tabletop) of workbenches is made of boards 50–60 mm thick (hardwood). Such a tabletop will not sag or tremble during work. The tabletop, depending on the nature of the work performed on the workbench, is covered with sheet iron 1–2 mm thick, linoleum or plywood. It is advisable to edge the tabletop around the perimeter to prevent parts from rolling off.
Under the workbench tabletop, it is advisable to have two or three drawers, divided into a number of cells for storing tools and small parts in a certain order.
The dimensions of the bench workbench should be as follows: length 1000–1200 mm, width 700–800 mm, height 800–900 mm.
Particularly convenient are workbenches with adjustable height legs, which, if necessary, allow you to set the workbench according to the height of the mechanic.
For ease of work, you can attach a folding seat to the workbench leg. To protect against shavings flying while cutting metal, it is advisable to protect the workbench with a wire mesh stretched over a frame.
Bench vice
A bench vise is a clamping device for holding the workpiece in the desired position. Depending on the nature of the work, chair, parallel and hand vices are used.
Rice. 1. Bench with a height-adjustable vice:
1 – lifting screw; 2 – frame; 3 – pipe;

Chair vice
They get their name from the way they are mounted on a wooden base in the form of a chair, but they can also be mounted on a workbench. Chair vices are used mainly for performing rough, heavy work associated with the use of shock loads - when chopping, riveting, bending, etc.
They consist of stationary 3

The chair vice is fastened to the workbench using a strap (legs) 2, and for greater stability, the fixed jaw 3
has an elongated rod 7, which is attached to the leg of the workbench.
Chair vices are forged from structural carbon steel.
The width of the jaws, depending on the type and size of the chair vice, has dimensions of 100, 130, 150, 180 mm, the largest opening of the jaws is 90, 130, 150 and 180 mm.
An overlay made of tool steel is welded onto the working parts of the jaws or special plates 8 are fastened with screws (overhead jaws, Fig. 2, b). The working surfaces of these plates are cut with a cross-shaped notch and hardened.
The advantages of chair vices are their simplicity of design and high strength. The disadvantage of chair vices is that the working surfaces of the jaws are not parallel to each other in all positions, as a result of which, when clamping, narrow workpieces are grasped only by the upper edges of the jaws, and wide ones - only by the lower edges (Fig. 2, b), which does not ensure fastening strength. In addition, when clamping, the jaws of the vice cut into the part, forming dents on its surface.

Parallel bench vice
are divided into rotary and non-rotary. In these vices, the movable jaw moves when the screw rotates, remaining parallel to the fixed jaw, which is why the vice is called parallel.
Rotary parallel vice
(Fig. 3) can be rotated at any angle.
This vice in the body of the fixed jaw 9
has a through rectangular cutout in which the nut

The body of parallel bench vices is made of gray cast iron. To increase the service life of the vice, steel (tool steel) prismatic jaws are attached to the working parts of the jaws with screws 8
with a cross-shaped notch. When clamping in a vice, dents may appear on the objects being processed from the notching of the hardened plates of the jaws. Therefore, to clamp the finished surface of a part (product), the working parts of the vice jaws are covered with overlay plates (“lips”) made of mild steel, brass or aluminum.

are manufactured with jaw widths: 36, 40, 50 and 56 mm and jaw openings of 28, 30, 40, 50 and 55 mm;
type 2 for small work (Fig. 5, b) with a jaw width of 6, 10 and 16 mm and a jaw opening of 5.5 and 6.5 mm. Sometimes the shape of a part does not make it possible to clamp it in the desired position, for example, when it is necessary to file a chamfer at a certain angle. In such cases, a slanting vice
(Fig. 5, c), in which the part is grabbed and clamped into the jaws of a parallel vice. For the convenience of simultaneous processing of several identical parts or thin long workpieces, special clamps are used (Fig. 5, d).
Hand vices are made from high-quality structural carbon steel grade 45–50; For springs, tool carbon steel grade U7 or steel grade 65G is used. It is also possible to manufacture springs from steel grades 60–70.
When working on a vice, the following rules should be observed:
– before starting work, inspect the vice, paying special attention to the strength of its attachment to the workbench;
– do not perform rough work on the vice (cutting, straightening or bending) with heavy hammers, as this leads to rapid destruction of the vice;
– when fastening parts in a vice, do not allow impacts on the lever, which can lead to breakage of the thread of the lead screw or nut;
– at the end of work, clean the vice with a hair brush from chips, dirt and dust, and lubricate the guides and threaded connections with oil;
– after finishing the work, separate the jaws of the vice, since in a compressed state, excessive stresses arise in the connection of the screw and nut.
Work tool
When performing locksmith work, they use a variety of tools and devices. A mechanic's working tools are divided into manual and mechanized.
Typical set of hand tools
divided by:
a) cutting tools - chisels, cross-cutting tools, a set of files, a hacksaw, scrapers, twist drills, cylindrical and conical reamers, round dies, taps, abrasive tools (brushes and pastes), etc.;
b) auxiliary tools - bench and straightening hammers, core, scriber, marking compass, die holder, wrench, etc.;
c) metalworking and assembly tools - screwdrivers, wrenches, bits, pliers, hand vices, etc.
Bench hammers are the most common impact tool. They are used to deliver blows when chopping, punching holes, riveting, straightening, etc. In plumbing, two types of hammers are used - with round and square strikers (Fig. 6, a). Hammers with a round striker are used in cases where significant force or impact accuracy is required. Square-faced hammers are chosen for simpler jobs. Hammers are made of steel grades 50, 40X or U7 steel; their working parts - the striker and the toe - are subjected to hardening to a length of at least 15 mm, followed by cleaning and polishing.
The weight of hammers, depending on their purpose, varies within the following limits: 50, 100, 200 and 300 g - for instrumental work, 400, 500 and 600 g - for plumbing work, 800, 1000 g - for repair work.
The materials for the handles of the hammers are dogwood, rowan, maple, hornbeam, birch - tree species whose wood is durable and elastic. The cross-section of the handle should be oval, and its free end should be one and a half times thicker than that of the hammer hole. The length of the handle depends on the weight of the hammer. On average, it is made 250–350 mm long; for hammers weighing 50–200 g, the length of the handles is 200–270 mm, for heavy ones – 350–400 mm. The end of the handle, on which the hammer is mounted, is wedged with a wooden wedge lubricated with wood glue, or with a notched metal wedge.
The chisel is used for cutting metal of various profiles into pieces, removing allowances from the surface of the workpiece, cutting down bosses and sprues on cast workpieces, rivet heads when repairing rivet joints, etc.
The chisel consists of three parts - working, middle and impact (Fig. 6, b
). The working part of the chisel has the shape of a wedge, the sharpening angles of which are selected depending on the material being processed. The middle part of the chisel is given an oval or multifaceted cross-section without sharp edges on the side edges, so as not to injure your hands. The head (impact part) of the chisel is shaped like a truncated cone.
Rice. 6. A set of basic percussion tools for a mechanic:
a – hammers, b – chisels, c, d – crosscuts, d – bits
The material for the manufacture of metalwork chisels is carbon steel U7A and U8A. The working part of the chisel is hardened at a length of 15–30 mm, and the impact part at a length of 10–20 mm.
A crossmeisel is a tool of the same type as a chisel, but with a narrower cutting edge. It is used for cutting out narrow grooves and grooves (Fig. 6, c). To cut out grooves in bearing shells and other similar work, special groove crosscutters are used (Fig. 6, d)
with pointed and semicircular edges. Crosspieces are made from carbon steel grades U7A and U8A and are hardened like a chisel.
The bit is used for punching holes in thin sheet steel, for installing holes drilled for rivets one against the other, for knocking out rejected rivets, pins, etc. Bench bits (Fig. 6, e)
made from U7A or U8A steel. The working part of the beard is hardened over the entire length of the cone.
Files are a cutting tool in the form of hardened steel bars of various profiles with parallel teeth cut on their surface at a certain angle to the tool axis. The material for the manufacture of files is carbon tool steel of grades U13 and U13A, as well as chromium ball-bearing steel ShKh15.
Files have different cross-sectional shapes: flat, square, triangular, round, etc. Depending on the nature of the work being performed, files of different lengths and with different numbers of notches are used.
There are three types of hand files: regular files, needle files and rasps. Ordinary files (Fig. 7, a)
made from carbon tool steel grades U13 and U13A. Needles are the same files, but smaller in size and with a notch only half or three-quarters of their length. The smooth part of the file serves as a handle. Needle files are made of steel U12 and U12A. They are used for processing small surfaces and finishing small parts.
Rasps differ from files and needle files in the design of the notch. They are used for rough processing of soft metals - zinc, lead, etc., as well as for sawing wood, bone, horn.
Scrapers (Fig. 7, b)
They are steel strips or rods of a certain length with carefully sharpened working edges (ends). By design, scrapers are divided into solid and composite; according to the shape of the working part - flat, triangular and shaped, and according to the number of cutting edges - single-sided, usually having wooden handles, and double-sided without handles.
Rice. 7. Files (a) and scrapers (b)
In addition to solid scrapers, recently replaceable scrapers have been used, consisting of a holder and insert plates. The cutting blades of such scrapers can be plates of tool steel, hard alloy and waste high-speed steel. The scrapers are not standardized. They are made from tool carbon steel U10A and U12A with subsequent hardening.
Screwdrivers (Fig. 8, a
) are used for screwing and unscrewing screws and screws that have a slot (slot) on the head. They are divided into all-metal with wooden cheeks, wire, rotary, special and mechanized. A screwdriver consists of three parts: the working part (blade), the shaft and the handle. Select a screwdriver according to the width of the working part, which depends on the size of the slot in the head of the screw or screw.
Wrenches are a necessary tool when assembling and disassembling bolted joints. Key heads are standardized and have a specific size, which is indicated on the handle of the key. The dimensions of the jaw (grip) are made in such a way that the gap between the edges of the nut or bolt head and the edges of the jaw is from 0.1 to 0.3 mm.
Wrenches are divided into simple one-size, universal (adjustable) and special-purpose wrenches.
Simple one-size keys come in flat one-sided and flat double-sided (Fig. 8, b); overhead deaf; for round nuts; end curved and straight. Straight and curved socket wrenches (Fig. 8, c) are used in cases where the nut cannot be screwed with a regular wrench.
Rice. 8. Screwdriver (s)
and wrenches
(b, c, d)
Simple one-size wrenches can screw nuts of only one size and one shape. Sliding (adjustable) wrenches (Fig. 8, d) differ from simple wrenches in that they can be used to unscrew or screw in nuts of various sizes. They have mouth sizes from 19 to 50 mm with different handle lengths.
Special keys are named according to the type of application, for example, a key for a valve, a key for a coupling nut, etc., as well as for working in hard-to-reach places.
A hand hacksaw is usually used for cutting metal, as well as for cutting grooves, slots in screw heads, cutting workpieces along the contour, etc. Hacksaws are either solid or sliding. The latter have the advantage that they can accommodate hacksaw blades of various lengths.
The use of the hand tools discussed above is associated with labor-intensive and low-productivity work, however, many locksmiths still use only hand tools, while a significant proportion of locksmith work can be mechanized by using various stationary and portable machines, as well as electric and pneumatic tools.
The use of such tools can significantly increase labor productivity. So, for example, tightening bolts and nuts using a mechanized impact wrench is carried out in
4 – 10 times faster than manually with a regular wrench; Surface cleaning using portable sanders is 5 to 20 times faster, and scraping with a mechanized scraper is 2 to 3 times faster than manual scraping operations.

can be divided according to the types of operations for which they are intended, into tools for chopping and cutting metals, filing, grinding and stripping parts, processing holes, threading, scraping and lapping, for assembling threaded connections, etc.
Depending on the type of engine, there are electrified tools, powered by electric current, and pneumatic tools, powered by compressed air.
Mechanized hand tools are also divided according to the nature of the movement of the working body - the spindle - into tools with rotational and reciprocating movement of the working body.
Among the mechanized electric tools, the most widely used are electric impact wrenches, electric pin wrenches, electric drills, grinding and polishing machines, electric files, thread cutters; Pneumatic tools include: impact wrenches, mechanical screwdrivers, hammers, drilling machines, etc.
Depending on the design of the body, there are manual mechanized tools with a breastplate, with a handle, pistol type and angular.
The design and operation of various types of power tools are discussed when describing the plumbing operations in which they are used.
Test tools
The correctness of the required dimensions and shape of parts during their manufacture is checked using a line (scale) measuring instrument, as well as straight edges, plates, etc.
Therefore, in addition to a standard set of working tools, a mechanic must have control and measuring tools. These include: scale ruler, tape measure, calipers and bore gauges, calipers, square, measuring rod, protractor, protractor, straight edge, etc.
The scale bar has division lines located from each other at a distance of 1 mm, 0.5 mm and sometimes 0.25 mm. These divisions make up the measuring scale of the ruler. For the convenience of measuring dimensions, each half-centimeter scale division is marked with an elongated stroke, and each centimeter division with an even more elongated stroke, above which a number is placed indicating the number of centimeters from the beginning of the scale. A scale ruler is used to measure external and internal dimensions and distances with an accuracy of up to 0.5 mm, and with experience, up to 0.25 mm. Scale bars are made rigid or elastic with a scale length of 100, 150, 200, 300, 500, 750 and 1000 mm, a width of 10–25 mm and a thickness of 0.3–1.5 mm from carbon tool steel grades U7 or U8.
Measurement techniques using a scale bar are shown in Fig. 9.
Rice. 9. Scale metal rulers and methods of measuring them
The tape measure is a steel tape, on the surface of which there is a scale with a division value of 1 mm (Fig. 10). The tape is enclosed in a case and is pulled into it either by a spring (self-rolling tapes), or by rotating a handle (simple tapes), or pushed in manually (grooved tapes). Self-rolling and grooved tape measures are manufactured with scale lengths of 1 and 2 m, and simple ones with scale lengths of 2, 5, 10, 20, 30 and 50 m. Tapes are used to measure linear dimensions: length, width, height of parts and distances between their individual parts parts, as well as the lengths of arcs, circles and curves. When measuring the circumference of the cylinder, a steel tape measure is wrapped tightly around it. In this case, the scale division coinciding with the zero division indicates to us the length of the measured circumference. Such methods are usually used when it is necessary to determine the length of the sweep or the diameter of a large cylinder, if direct measurement is difficult.

To transfer dimensions to a scale bar and control the dimensions of parts during their manufacture, calipers and bore gauges are used.
Calipers are used to measure the external dimensions of parts: diameters, lengths, thicknesses of shoulders, walls, etc. It consists of two legs 150–200 mm long, curved along a large radius, connected by a hinge (Fig. 11, a ).
When measuring, take the caliper by the hinge with your right hand and spread its legs so that their ends touch the part being tested and move along it with little effort. The size of the part is determined by placing the legs of the calipers on the scale ruler.
A spring caliper is more convenient (Fig. 11, b); the legs of such a caliper tend to move apart under the pressure of the annular spring, but nut 2, screwed onto a clamping screw 3, mounted on one leg and freely passing through the other, prevents this. By rotating the nut 2
Using screw
3
with a fine thread, the legs are set to a size that cannot be changed arbitrarily. The measurement accuracy with calipers is 0.25 – 0.5 mm.
Rice. 11. Calipers and bore gauge. Measurement methods
It is made from carbon tool steel U7 or U8, and the measuring ends at a length of 15–20 mm are hardened.
The bore gauge is used to measure internal dimensions: diameter of holes, sizes of grooves, recesses, etc. In Fig. 11, a, b
ordinary and spring bore gauges are shown. Unlike calipers, it has straight legs with bent jaws. The device of the bore gauge is similar to that of a caliper.
When measuring the diameter of a hole, the legs of the bore gauge are spread until they lightly touch the walls of the part and then inserted vertically into the hole. The measured size of the hole will correspond to the actual size only if the bore gauge is not skewed, that is, the line passing through the ends of the legs will be perpendicular to the axis of the hole. The size is measured using a measuring ruler; in this case, one leg of the inside gauge is supported by the plane to which the end face of the measuring ruler is pressed at a right angle, and the size is measured along it (Fig. 11, c).
In Fig. 11, d shows the measurement of the spread of the legs of the caliper using a caliper. This ensures greater accuracy (up to ±0.1 mm) than when reading using a ruler.
Bore gauges are made from carbon tool steel U7 or U8 with hardening of the measuring ends at a length of 15–20 mm.
The measurement accuracy that can be obtained using a scale ruler, folding meter or tape measure does not always satisfy the requirements of modern mechanical engineering. Therefore, in the manufacture of critical machine parts, more advanced scale tools are used, which make it possible to determine dimensions with increased accuracy. These tools primarily include calipers.
Vernier calipers are used to measure both external and internal dimensions of parts (Fig. 12, a). It consists of a rod 8
and two pairs of jaws: lower
1
and
2
and upper
3
and 4. Jaws
1
and
4
are made integral with frame 6, sliding along the rod.
Using screw 5, the frame can be fixed in the required position on the rod. The lower jaws are used for measuring external dimensions, and the upper jaws are for internal measurements. The depth gauge 7
is connected to the movable frame 6, moves along the groove of the rod
8
and serves to measure the depth of holes, grooves, recesses, etc. Whole millimeters are counted on the rod scale, and fractions of a millimeter are counted on the vernier scale
9,
placed in the cutout of
the caliper 6 .
The vernier scale has ten equal divisions over a length of 9 mm; thus, each division of the vernier scale is less than a division of the scale (ruler) by 0.1 mm. When measuring a part with a caliper, first count a whole number of millimeters on the rod on a scale, looking for it under the first stroke of the vernier, and then use the vernier to determine tenths of a millimeter. In this case, mark the division of the vernier, coinciding with the division on the rod. The ordinal number of this division shows tenths of a millimeter, which are added to the whole number of millimeters. In Fig. 12, b
three positions of the vernier relative to the rod scale are shown, corresponding to the dimensions: 0.1; 0.5 and 25.6 mm.
Rice. 12. Vernier caliper with measurement accuracy of 0.1 mm
It is often necessary to manufacture parts whose surfaces meet at different angles. To measure these angles, squares, angle gauges, protractors, etc. are used. Squares and angle gauges are the most common tools for checking right angles. 90° steel squares come in a variety of sizes, solid or multi-piece (Figure 13).
Squares are made in four accuracy classes: 0, 1, 2 and 3. The most accurate squares are class 0. Accurate squares with chamfers are called patterned (Fig. 13, a,
b).
To check right angles, a square is placed on the part being tested and the correct processing of the angle being checked is determined in the light. When checking the outer corner, the square is placed on the part with its inner part (Fig. 13, c),
and when checking the inner corner - with the outer part.
Having placed one side of the square on the machined side of the part, pressing it lightly, combine the other side of the square with the machined side of the part and judge by the resulting gap the accuracy of the right angle (Fig. 13, d). Sometimes the size of the lumen is determined using probes. It is necessary to ensure that the square is installed in a plane perpendicular to the line of intersection of the planes forming a right angle (Fig. 13, e).
With inclined positions of the square (Fig. 13,
f, g),
measurement errors are possible.

, hingedly fixed between two strips of the holder.
The hinged fastening of the holder allows the ruler to occupy a position in relation to the holder at any angle. The mold is installed at the required angle according to the sample of the part or along the corner tiles. The required angle is fixed with screw 3
with a wing nut.
A simple small scale is used to measure (transfer) only one angle at a time.
The universal tool is used to simultaneously transfer two or three corners.
To measure or mark angles, to adjust small tools or determine the magnitude of the angles transferred by them, goniometer tools with an independent angle are used. Such tools include protractors and protractors. Protractors are usually used to measure and mark angles on a plane. Goniometers are simple and universal.

A simple protractor consists of a ruler 1
and protractor

(Fig. 15, a).
When making measurements, the protractor is placed on the part so that the ruler 1
and the lower edge of the m shelf of the protractor

coincide with the sides of the part being measured 3. The angle value is determined by the indicator

which moves along the protractor scale along with the ruler. A simple goniometer can measure angles with an accuracy of 0.5–1°.

Under the magnifying glass, parallel to the glass disk, there is a small glass plate on which is a pointer, clearly visible through the eyepiece of the magnifying glass. Ruler 2
can be moved longitudinally and

4 When ruler 2
is rotated in one direction or another, disk

and magnifying glass 6 will rotate in the same direction. Thus, a certain position of the ruler will correspond to a very specific position of the disk and magnifying glass.
After they are secured with the clamping ring 7,
observing through a magnifying glass 6, the readings of the inclinometer are taken.
An optical inclinometer can measure angles from 0 to 180°. Permissible errors in optical inclinometer readings are ±5 '.
Straight edges are used to check planes for straightness. In the process of processing planes, rulers are most often used. They are divided into pattern rulers with a double-sided bevel, triangular and tetrahedral (Fig. 16, a).
Rice. 16. Pattern rulers: a – structural forms of rulers: double-sided, triangular, tetrahedral, b – technique of applying a ruler
Pattern rulers are manufactured with high precision and have thin ribs with a radius of curvature of 0.1–0.2 mm, thanks to which it is possible to very accurately determine the deviation from straightness using the light slit method (through transmission). To do this, the ruler is installed with its edge on the surface of the part being checked against the light (Fig. 16, b). Any deviations from straightness will be noticeable between the ruler and the surface of the part. In good lighting, deviations from straightness of up to 0.005–0.002 mm can be detected. Pattern rulers are made from 25 to 500 mm in length from carbon tool or alloy steel with subsequent hardening.
Storage and care of measuring instruments. The accuracy and durability of an instrument depend not only on the quality of workmanship and skillful handling, but also on proper storage and care.
The simplest measuring tool is usually stored in a workbench drawer, where it is arranged in a certain order by tool type and size. Calipers and measuring rulers are stored in special cases with lockable lids. To protect instruments from rust, lubricate them with a thin layer of pure technical petroleum jelly, after wiping them well with a dry cloth. Before using the tool, remove the lubricant with a clean cloth or by washing it in gasoline. If rust stains appear on the instrument, it must be placed in kerosene for a day, then washed with gasoline, wiped dry and lubricated again.

How to calculate the dimensions of a workbench for a garage: recommended dimensions
The dimensions of the structure are selected individually depending on the preferences of the owner, as well as taking into account the expected types of work. The width of typical structures is in the range of 0.7-1.2 m, and the length is from 1.5 to 2 m. Workbenches are single and double. The differences between these designs are the length and number of nightstands with drawers. If the desktop is single, in this case the optimal dimensions of the tabletop will be 0.8 x 0.8 x 1.5 m. In double designs, the length is increased to 2.8 m.
Drawing of a simple carpentry workbench with dimensions for a garage.
The height of the carpentry workbench is selected taking into account the height of the craftsman who will work at it. Typically this figure varies from 85 to 95 cm. It is quite easy to check the correctness of the calculations. If, standing at the table, the master can freely rest his palms on its lid, then the height is chosen correctly. It is very important not to make a mistake with this indicator, since frequent stretching and bending is harmful to a person’s back and can lead to rapid fatigue.
The same applies to metal structures, which can also be used for plumbing work. In any case, the desktop must be stable and very durable. The minimum thickness of the lid is 5 cm. Textolite or linoleum is used as upholstery, which will protect the tabletop from damage. In metalworking workbenches, the wooden surface of the workplace is covered with a steel lid. The minimum thickness of this coating is 5 mm.
Manufacturing instructions
The workbench, which will be constructed from the specified materials, has a length of 2.2 m and a width of 75 cm. Such impressive dimensions will allow you to place a vice, emery and other tools in the corners of the table.
Assembling the base
The construction of the workbench frame is carried out according to the following algorithm:
- The material is cut into its constituent particles. A profile pipe is necessary to form the base. A steel angle is required to create ribs that give the mechanism strength. It is divided into several parts, after which the power base is assembled on it. It will be useful in making edging for the table top. Boards will subsequently be placed on top of it. In order to construct the guides on which the side panels will be fixed, it is necessary to use a steel strip. It will be useful as the basis of the brackets that hold the plywood and boxes together. The table drawers are made of plywood sheets.
- After this, they proceed to welding the power base of the device. The procedure begins with connecting the parts of the tabletop - two pipes of 220 cm and two of 75 cm. The frame must be welded in such a way that another base, which would consist of corners, is placed on top of it. Boards from the table top are laid inside it. In order to reinforce the tabletop, it is necessary to weld another series of steel pipes every 40 cm. They are needed to serve as strength ribs.
- The next step in assembling the workbench is to weld the four side legs along its edges. The length of each of them is 90 cm. In order to make the structure stronger, it is necessary to weld the power gaps between the legs of the device.
- After this, the basic base should be considered complete and we proceed to welding the structure for the boxes. In this case, steel pipes are used, on the basis of which square-shaped frames are made. They must be welded to the tabletop on both sides of the table. Due to the presence of longitudinal strength ribs, they are strengthened.
- Then they begin to make the base for the tabletop. To do this you will need four steel corners. The length of two of them is 220 cm, and the length of the other two is 75 cm. It is necessary to weld this structure so that wooden boards are placed inside it.
- The frame based on the angle is placed on a pipe base and then welded. The result should be a reinforced tabletop. Its height is 8 cm, and there are stiffening ribs inside the device.
- The final step in constructing a metal workbench is to weld the panel sheathing onto which the tool will be attached. In this case, one metal corner is required, the length of which is 220 cm, and four more corners with a length of 95 cm. Two of these elements are fixed on the side parts of the structure, and two more are located in the center. They are necessary for the overall strengthening of the device. The tool panel is fixed to the tabletop by welding.
- The base, made of pipes and corners, is completely ready. This structure needs to be strengthened. Brackets cut from a strip of steel are welded to the side parts of the table. The number of these parts is 24.
- One through hole must be drilled in the central part of all brackets. They are needed to attach the back and sides of the plywood table to the metal base of the workbench.

Assembling desk drawers
This process consists of the following steps:
- The plywood sheet must be cut into pieces that are connected to each other using screws. The number of boxes produced should vary depending on what kind of tools are planned to be stored inside them. For small parts you will need about three boxes, while for storing large parts, two boxes will be enough. They can be placed on both sides of the table, or retractable structures can be constructed on one side, and regular open shelves can be placed on the other side.
- Upon completion of the assembly of the drawers, it is necessary to weld metal strips for boxes equipped with special holes between the side parts of the sections. On the inside, the slides for the guide boxes will be attached to these holes.
- After this, boards begin to be laid into the base of the tabletop. Their thickness should be 50 mm. The wooden material needs to be cut into various pieces of the required length. If there are long boards available, then you will need three blanks 219 cm long and 24.5 cm wide. If you only have short boards, make blanks that can be placed across the table. For this purpose, wood 20.5 cm wide is crushed into ten pieces, the length of which is 74 cm.
Final work
After assembling the boxes, follow these steps:
- Before the wood is placed inside the table base, it must be thoroughly treated with an antiseptic. This will protect the workpieces from damage by beetles and other harmful insects, as well as from rotting.
- An important step in constructing a workbench is painting all metal elements. This procedure is used to protect the device from damage by rust. It is preferable to use an anti-corrosion, weather-resistant type of coating. Particular attention must be paid to welding seams.
- If there are any irregularities or drops of metal on the surface of the mechanism, they must be thoroughly cleaned before proceeding to painting. For this purpose, an angle grinder equipped with a disk for metal processing is used.
- The device is given time for the paint to dry, after which the boards begin to be laid on the tabletop. Do not press them too tightly together inside the base. The reason for this is the ability of wood to dry out and expand after changes in humidity and temperature conditions. It is necessary to maintain a gap of several millimeters between the workpieces.
- The surface of the boards is pre-sanded. This will help to lay a sheet of metal on top of the wood. Along the entire perimeter of the table, it is necessary to fix the boards to the frame using self-tapping screws.
- After this, they begin to attach the top sheet of steel. It is possible to weld it to the countertop, but there are wooden pieces inside the device, and there is a risk that they will ignite from a spark. Therefore, for safety reasons, the sheet is attached to wooden boards using hidden screws.
- Before this, it is necessary to treat the metal surfaces with a rust converting agent. This covering material looks like a transparent paint coating. It has the ability to quickly recover and prevents the development of corrosion.
- The steel tabletop can be painted with the same paint that was used to paint the frame. This will improve the aesthetic appearance of the device, but after some time the paint will begin to scratch.
- The assembled boxes are placed on the guides, after which the plywood sheet is attached to the sides, power panel and shelves. After this, the plywood should be coated with a special protective compound.
- Then you need to properly design the power shield. You can attach screws or hooks to it for some things. For the convenience of working at a workbench, you can attach a table lamp with a bending stand to it.
- A vise is installed on the workbench. This is a heavy tool, so it is not recommended to attach it directly to the tabletop. Instead, a 10mm thick metal spacer should be placed between the steel sheet and the vice. It is necessary to make through holes in it. Holes are drilled in the same places on the tabletop, after which the structure is fastened with anchor bolts.
The optimal place to install a homemade workbench
It is imperative to take into account the characteristics of the room before making a bench with your own hands.
It is recommended to install the workbench against the wall in one of the corners.
Drawings of the future structure, as well as its dimensions, are selected taking into account all the conditions:
- Type of design – stationary or mobile.
- Features of the tabletop: a fixed work area with constant dimensions or a folding lid.
- The functional content of the workbench is a simple design in the form of a table or a functional option with additional drawers, shelves or holders for storing tools.
- Table configuration - corner, straight or U-shaped.
- Installation option - a structure mounted near a wall or a free-standing table.
Most often, there is very little free space in the garage or workshop. According to the recommendation of experts, when making a workbench with your own hands, folding structures are given greater preference. They are mostly stationary and are usually installed near a wall. In this case, it is better to use the corner area of the room or its least used area.
If you plan to make a compact portable workbench with your own hands, you can install it anywhere. After use, the folding structure is simply removed to another place or retracted.
Note! If the room has windows or ventilation is provided, drafts may appear. It is not recommended to place a workbench in their area of effect, as this can cause problems with the neck and back, as well as with muscles heated during work.
Technology for creating a carpentry workbench with your own hands: drawings, dimensions and procedure
The most convenient option for a private home or garage is a design with a hinged lid. Unlike a folding workbench, its working surface rotates rather than unfolds. This design option has a completely different structure, although it is no less functional and compact.
Drawing of a wooden carpentry workbench with dimensions.
Mobility is achieved due to the presence of wheels installed on the bottom. To prevent arbitrary movement of the structure, it is advisable to use rollers with a locking function. As a last resort, you can install a wedge under the wheels, but this option is not so convenient and practical.
On the right side of the design there are pull-out drawers for convenient storage of small items. If the table will be used by a left-handed master, they should be placed on the other side so that everything you need is at hand. In addition, the workbench is equipped with a special holder. It is made of perforated plywood and mounted on the back of the cabinet. Thus, it becomes possible to make maximum use of the surface of the workbench and organize additional space for storing small tools for carpentry.
On the left or right (for left-handers) there is an open compartment in the design. It is suitable for placing narrow, tall equipment such as a drilling machine. Thanks to the roller mounted on the edge of the tabletop, the process of processing long lumber is greatly simplified, and due to the multi-socket outlet, you can simultaneously connect several tools to the network.
Video description
This video shows the process of making a carpentry workbench:
At the last stage of assembly, you need to sew up the back and sides of the workbench table with plywood, and also make a tabletop. If you decide to make the top from wood materials, you can use several sheets of plywood securely glued together. To obtain a more reliable, durable bench, you can install a two-millimeter metal sheet as a tabletop. To store tools and various materials that may be useful to a craftsman in his work, it is worth making shelves or drawers for the workbench.
Drawing of a wooden workbench with your own hands and materials for work
Based on the design drawing, you need to make all the parts necessary for its assembly. The overall dimensions of the workbench in this case are 175 cm (length) and 76 cm (width). A distinctive feature of this table is its three-layer lid, which has an increased margin of rigidity and strength. The upper and lower levels are made of plywood sheet with a smooth surface. The middle layer of the table top is stacked, it is formed from boards.
Note! It is imperative to leave a gap between the boards in the middle layer of the tabletop. This space is necessary to allow the threaded rod to rotate freely.

Do-it-yourself carpentry workbench: assembling the base
Before making a workbench from wood, it is better to estimate the amount of work in advance and outline the procedure. Most of the table parts are fixed using screw connections. To facilitate the assembly process, it is advisable to make holes for them in the plywood in advance in the appropriate places. For these purposes, you need to use a drill whose diameter is approximately 1/2 or 1/3 smaller than the diameter of the fastener itself.
Having prepared all the necessary tools and materials, as well as carefully studying the drawings of the carpentry workbench, you need to make all the structural parts. A circular saw is suitable for cutting wood and plywood. After this, the end part must be sanded so that the edges of all elements are smooth. This will not only simplify the assembly process, but will also avoid problems with joining parts.
To assemble the workbench base, you need to secure the frame and base plate.
First of all, the base is assembled. It consists of a base plate where a cabinet with drawers will be installed, an open area for equipment and stiffening ribs to strengthen the structure. To do this, you need to assemble the frame and fix the plate on it. For fixation, M50 fasteners should be used.
Note! Only dry lumber can be used for work. The optimal wood moisture content is 12%.
How to make a workbench out of wood with your own hands: installing a cabinet and tabletop
The next step is to install the side tables. In the process of assembling these elements, it is necessary to take into account that the plywood, which is attached to the back of the structure, must be fixed precisely to the frame.
Installation of the workbench tabletop must be done on a finished frame.
It is also worth paying attention to the fact that the outer plane for the left cabinet, used as a support, is longer than its inner part. To make a workbench made by yourself more rigid, this element must be fixed not to the base plate, but fixed to the frame. The cabinets themselves are installed on a base plate. For this, two types of fasteners are used. The lower plane is fixed with screws size M20-M24. For the inner sides, corners should be used.
After the cabinets are installed, you need to accurately determine the middle on their inner sides. This marking is necessary in order to cut U-shaped holes for the turning rod. This must be done so that the center of these holes is located at a distance of 2.2 cm from the bottom plane of the top cover on the cabinet.
Once everything is ready, you can thread the threaded rod through the holes in the four uprights. In this case, its ends should protrude beyond the workbench by about 4-5 cm. They are fixed (without tightening) with locknuts and washers.
Using clamps or screws, you need to install the support strips for the tabletop. They will be placed here temporarily - only so that the position of the tabletop and its horizontal plane can be aligned. Next, three layers of the cover are assembled, which are fixed with screws and adhesive. After this, the bars are removed and the result is checked. The table top should rotate freely.
Then the side surface of the lid (both rotary and stationary) is reinforced with slats. Finally, you need to install the turning handles and locking latches.
The final stage of assembling a workbench for carpentry work
When all the elements of the frame have been assembled, you can begin installing the drawers and fittings. First of all, you need to install the guides in the cabinet located on the right. To make work more convenient, it is better to use temporary inserts in the form of wood panels.
At the final stage, the product is polished.
Instead of homemade wooden guides, you can use ready-made factory-made retractable systems. Such fittings (provided they are of high quality) operate silently and trouble-free. These guides can be designed for either full or partial extension. Next, the storage boxes are assembled. For this, screws and adhesive intended for wood are used. The size of the facades is selected taking into account the dimensions of the cabinet.
Note! It is imperative to leave a small gap (about 1-3 mm) between the facades, otherwise the drawers will not slide out well.
As a functional addition, a movable bar can be installed on the spacer, along which one or more guide rollers will move. Their number depends on what work will be carried out in the workshop. So that the roller can move freely up and down, a slot is made in the movable bar for it, and then a wing nut is installed, which will serve as a clamping screw.
A roller is installed in the upper part of the movable bar. To do this, use a U-shaped holder. It must have slots or holes on the sides intended for the roller axis.
Sometimes craftsmen resort to other carpentry tricks, and homemade devices made with their own hands become an excellent addition to a workbench and other equipment:
- compact stands and holders for cutters;
- sliding stops for miter saw;
- magnetic pads on the jaws of clamps (pipe);
- devices for creating precise corner holes with a drill;
- guide bars for circular saw;
- MDF benchtop machines for eccentric sander, etc.
Ready-made carpentry workbench with swivel top and drawers.
Next, you need to install carpentry tools on the workbench with your own hands. When installing electrical equipment on a hinged cover, it is imperative to maintain balance. Do not load only one side or one corner of the workbench. The set screws are buried at least 2/3 of the thickness in the turning part of the tabletop. This allows you to achieve reliable fixation, because electrical carpentry equipment has considerable weight. In the side areas, where the working area remains stationary, this fastener can pass through the entire thickness of the cover.
In its finished form, a homemade workbench with a rotating tabletop and equipment installed on it is very convenient and functional. To protect wood from the negative effects of moisture, it is advisable to coat it with a primer or even paint. All parts are processed before assembling the workbench and must be thoroughly dried. Painting will also improve the appearance of your workshop bench.
How do vices work?
