Do-it-yourself miter saw from a circular saw: step-by-step instructions for making a miter saw, a homemade version with a broach and a protractor

A crosscut is a device for cutting a product crosswise to length, and not only wooden materials, but also any other materials that can be cut by circular saws (for example, plastic). There are a sufficient number of hand-held circular saws (so-called parquet saws) on the market, with which you can:

adjust molded products to size;
remove excess material by cutting out blanks;
or even make a long longitudinal cut.

But all these actions are carried out literally in weight, that is, without rigidly fixing the tool or workpiece. In some situations, the achieved quality may be quite sufficient, but sometimes increased accuracy of the workpiece dimensions is required. In this case, specialized cross-cutting machines, which are sold in any supermarket of construction and finishing goods, come to the rescue.

But such machines are very expensive. And besides, as a rule, the need for them never lasts long, unless you engage in carpentry professionally. In this case, it makes sense to build a homemade miter machine using an existing hand-held circular saw. But how to properly make a homemade miter saw from a circular saw? We will talk about this on the pages of this article.

What will be needed for production?

The working body of a factory trimmer (motor, body, cutting disk) is similar to a conventional manual circular saw. Therefore, the hand saw can easily be adapted for miter cutting. The first thing you need is the handsaw itself. All that remains is to add a frame for attaching the electric saw and placing workpieces.

A variety of design options are possible, from the simplest platforms for straight sawing to complex devices: sawing at angles, with broaching for large-sized workpieces. Therefore, different materials and parts can be used.

For the frame, plywood with a thickness of 10-20 mm is best suited. Its advantages over other materials:

Not brittle like chipboard, doesn't bend like fiberboard.
Doesn't warp like wood.
It is easy to process and attach in any home workshop, unlike metal.
Under the roof, without moisture, it lasts quite a long time.

In addition to plywood, you will need:

Fasteners for connecting frame parts (screws, studs, bolts, nuts).
Wooden blocks or metal corners for joints and hinges.
Hinge axis (pin, long bolt, washers, nuts).

The following tools are required and may be required:

Sawing tool (hacksaw, jigsaw, circular saw).
Drill or screwdriver (we also recommend reading how to make a circular saw from a drill).
Drills of the required diameter.

The dimensions of the blanks for the bed will depend on what design the master chooses and on the dimensions of the circular saw itself, on the basis of which the trimming is done. For example, to trim a fence picket, you will need a bed length along the workpiece (1.2-2 m). For small parts, a more compact bed is suitable.

The photo shows an example of the so-called monkey - a cutting circular saw with an abrasive disc for metal, but it serves as an example of what a small frame can be used in such a design.

The cost of materials and parts cannot be calculated, since they will be different in each individual case. Someone may simply already have everything they need to make it, and the parts won't cost anything. If purchased, the cost will depend on what design the master chooses.

Milling

Discs

Such nozzles are available in various designs. The main difference between the devices is the size of the abrasive grains.

Which tool should you choose?

Manual circulars are used, which the owner already has. The peculiarity of homemade miter saws is that on most designs they can be easily removed and used for their intended purpose, like a hand saw. Therefore, the need to buy a second circular does not always arise. But in the following cases it is better to buy a new or second circular:

The saw is old, its service life is expiring, there is no point in making a stand for it, because a new saw may not fit.
The design is such that it takes a long time to remove and install the saw.
The operations are constantly alternating, and you have to take turns working either with a miter saw or with a hand saw. Frequent installation/disassembly is inconvenient.
Two people work, one on a cross-cut saw, the other with a hand saw.

The selection criteria are the same as for a manual circular saw. When cutting, the circular saw engine experiences almost the same, and even less, loads as when working with a hand saw. Therefore, increased power is not required for simple trimming. The power will not be superfluous when cutting with a broach, since it cuts dimensional workpieces.

Any circular saw is suitable for trimming. Optimally – average power and price, from a brand with a good reputation for quality.

For example, Makita HS7601, its technical characteristics:

Power 1200 W
Cutting depth 66 mm, at an angle of 46 mm.
Disc speed 5,200 rpm.
Disc diameter 190 mm, seat diameter 30 mm.
Price about 10 thousand rubles. 2022

Or Interskol DP-190/1600M with technical characteristics:

Power 1600 W.
Cutting depth 63 mm at right angles.
Disc speed 4800 rpm.
Disc diameter 190 mm, seat diameter 20 mm.
Price from 6,000 rubles, 2022.

We also recommend reading interesting articles about choosing a circular saw for the home and about the rating of the 10 best circular saws; it contains all the most necessary information that will definitely come in handy when choosing a tool.

Interskol DP 190 is an excellent option for homemade trimming

Sanding wood

If you decipher the abbreviation angle grinder, it is clear that finishing is the main purpose of the “grinder”.

Cord brushes

They are used primarily for primary (rough) sanding of wood, when it is necessary to smooth out the unevenness of the sample.

End discs

The name speaks for itself. These attachments are used to process the end parts of wooden blanks (cuts). They are especially effective if you have to deal with corner (oblique) cuts.

How to make a crosscut from a manual pendulum-type circular saw?

The simplest trim using a manual circular saw can be done in a few minutes. To do this, you will need a door hinge, preferably with one long side (strip). One side is attached to the circular platform, the other to the bed. The entire step-by-step manufacturing process is shown very clearly in this video:

It didn’t even require plywood and fasteners to make the frame. An ordinary wooden pallet was used as it. You can also use any suitable ready-made platform.

In some cases, if there are no slots in the wooden frame for the disc to pass through, they are cut through with the disc itself. Before this, the fastenings of the circular saw are loosened in order to make a cut with slight shifts to the left and right. This way the slot will be slightly wider than the disk, and during operation the disk will not rub against the sides of the slot.

The advantages of this solution:

extreme ease of manufacture,
a minimum of parts (a hinge and two bolts with nuts and washers).
minimum tools for manufacturing (drill, drill bit, wrench).
speed and ease of transfer from a hand saw to the miter mode and back.

Minuses:

limited ability to cut at angles in length and height.
there is play in the hinge axis; when sawing, you need to select one side and press the saw against it. In another case, due to backlash, the cut may be inaccurate (plus or minus 2-5 mm).
changes to the safety device – the disk cover is always fully open.

An example of another homemade trim with a specially made frame instead of a pallet is here:

The method is a little more complicated, since you have to make a frame out of plywood. But the advantages of this design are compactness and mobility. It can be put away on a shelf, placed on a workbench, etc.

Trimming based on a grinder

To solve this problem, a grinder is often used. It is ideal for making your own miter machine for processing end surfaces. The homemade version will have the following technical characteristics:

The disc speed of the grinder should not be less than 4500 rpm;
The cutting length is 350 millimeters. Note that this figure is significantly higher than that of a factory tool, which belongs to the middle class.

The created design allows you to remove the grinder from the table and use it as a regular tool.

When considering how to make a similar embodiment, we note the following points:

the cutting tool is mounted on an axis, which is represented by a car wheel. This moment determines the possibility of facing at an angle. To fix the rotating mechanism, a bearing with a diameter of 150 millimeters is used. To fix the grinder, a special mechanism is used, which is mounted on a rotating axis. After a certain time, it is recommended to lubricate this axis, as there is a possibility of squeaking;
To fix a certain angle during the production of a machine on a bearing, special ears are welded on the outside. Fixation is carried out using a screw, for example M6. The ears should be attached so that there is not a large distance between them. Otherwise, there is a possibility of strong backlash, which will significantly reduce the processing accuracy;
the possibility of chips getting inside the bearing should be excluded. This is due to the fact that chips inside the bearing lead to wear and unsmooth rotation of the cutting tool. The chips can be quite small, which will lead to rapid wear of the bearing. Adding a lubricant also eliminates the possibility of rapid bearing wear;
the broach can be created using a shock absorber. It is recommended to choose truck versions, as they are more resistant to environmental influences. Broken shock absorbers can also be used. Preparing the shock absorber involves removing the oil and drilling holes, which become a kind of ventilation. The holes should be covered with a mesh with small holes in order to eliminate the possibility of wood chips getting into the ventilation system;
In order not to feel a strong jerk at the beginning of work, you should equip the angle grinder with a soft start module. At the very beginning of the start-up, this module reduces the number of revolutions and gradually spins the disk up to operating speed. It is not possible to make a soft start module yourself; it must be removed from another device or purchased separately.

The last stage of production can be called creating a shield for the saw. This element eliminates the possibility of foreign bodies entering the cutting zone. You can use your own cross-cutting machine at home.

However, the design in question also has significant disadvantages that should be taken into account. These include:

A DIY cross-cutting machine is very noisy. This is due to the peculiarities of the grinder’s work. During processing, noise appears, which is almost impossible to reduce;
The cross-cutting machine is used for high-quality processing of end surfaces. That is why quite a lot of attention is paid to the accuracy of the position of the grinder with the disc relative to the workpiece. To adjust the position of the grinder with the disk, trimming bars are used. The rod should be fixed with a bolt, after which processing can be carried out.

The drawings of the cross-cutting machine indicate that it can be quite easily installed in almost any workshop. One should take into account the fact that the structure is small in size, and the workpiece can be quite large. In order to eliminate the possibility of loss of accuracy during processing, the structure should be secured to the base.

Particular attention is paid to the type of disk installed. Initially, the grinder was intended for metal processing, which determines the presence of a large number of metal discs. But there are also discs for wood processing, which have their own characteristics

But there are also discs for wood processing, which have their own characteristics.

In conclusion, there are quite a few blueprints that can be used when creating a cross-cutting machine. Some are quite simple to implement, others are difficult to implement.

How to do it with a broach?

If a conventional crosscut saw only has a pendulum stroke (in a semicircle), then on a crosscut with a broach the saw can also move horizontally. This type of trim can cut to size along the length of workpieces of greater width.

If for a simple trim the width of the workpiece is limited by the width of the disk at maximum immersion in the material, then for the version with broaching the width of the saw stroke along the guides is added.

Factory miter saws with a broach design have both a pendulum stroke in a semicircle and a horizontal stroke of the saw along the guides.

Most homemade crosscuts with broaching are simpler in the very principle of their design. They do not have a pendulum motion in a semicircle, but only horizontal movement along the horizontal.

An example of making a homemade crosscut with broaching in this video:

This design cannot be called a crosscut in its pure form; it is rather an analogue capable of performing certain operations. Its plus:

availability of materials,
comparative ease of manufacture,
ability to cut to the width of the workpiece.

Minuses:

limited functionality, you cannot cut at angles in different planes,
it is inconvenient to insert long workpieces under the saw blade,
for long workpieces that are placed perpendicular to the homemade bed and saw, you will have to additionally make a support workbench.

Assembling a complex machine

There is an option with a more complex and heavier design. She can definitely handle cutting pipes. In this case, a homemade installation will not require the use of a circular saw as a component of the machine. But for certain stages of work it is better to have a circular saw on hand.

Depending on the selected components, you can get a machine with increased power. To assemble the machine yourself

by hand you will need:

Electric motor with a power of about 900 W. If you have to regularly cut pipes, you can choose a more powerful electric motor;
Metal sheet;
Metal corners;
Channel;
Hinge groups;
Bulgarian;
Welding device;
File;
Spring of impressive power.

When everything you need has been collected at the workplace, you can begin assembling the cross-cutting machine with your own

hands.

A homemade bed can be made with your own hands by using adjustable supports, metal corners and bed posts.
A sheet of durable metal acts as a working surface. You need to make holes in this sheet table and process them using a file.
To weld a pendulum stand for a future machine, use channels and a welding machine. The structure is installed on a metal sheet. The approximate height of the stand is 80 centimeters.
The stand for the electric motor is made of a metal sheet in the form of a fixed plate. Be sure to install the stand on its hinges.
The stabilizer of the electric motor of a cross-cutting machine is a powerful spring. If you manage to find one, you can completely abandon the belts and pendulum.
Using the eyebolt, you can tension and adjust the belts. The pendulum can be made of metal to make the structure reliable and durable.
Use the actuating tool to select a disk of the required diameter. For household purposes, a saw blade with a diameter of 400-420 millimeters is usually sufficient.
Be sure to provide protective covers, since assembling such a machine is accompanied by a certain degree of danger.

When choosing the option of assembling a machine with your own hands, rather than purchasing a factory-made cross-cutting machine, you need to understand that there will be quite a serious difference between them in the quality, accuracy and error of processing wood, pipes, metal and other products.

Safety during work

Safety precautions when using homemade and factory trimmers are no different. Basic Rules:

The hand should not approach the cutting disc closer than 20-30 cm. When cutting small parts, clamps are used.
Care must be taken to ensure that the electrical wire does not get caught in the cutting blade.
Do not work outdoors during rain to avoid water entering the electric motor through the ventilation grille and socket.
You cannot work tired, intoxicated, or with reduced reaction.

A circular saw is a very noisy type of instrument; long-term use of it has a negative impact on the hearing organs, so you must use headphones. Also with safety glasses, because... During the sawing process, a large amount of small sawdust is formed, which fly into the eyes.

Types of hand tools

The following devices are a typical set of accessories for high-quality work. Not a single master can do without them.

Ruler - guide rail

It is a bar on which a size scale is applied (in some cases graduated). It serves to guide and at the same time limit the hand saw blade during operation. The ruler is laid out on the prepared sheet, secured with a clamp, the saw blade is pressed with its end and guided along the workpiece to the required mark on the scale.

Guide rail with dimension scale. The saw blade is guided along the end, and the saw itself is guided directly along the guide

Rip fence - limiter

All work using a hand-held circular saw is carried out on a workbench. Unlike stationary bench tables, workbenches are not equipped with additional stops. In this case, you can use a parallel stop.

It is a rail, which at one end has an L-shaped bar and a clamp for attaching it to a circular saw. The corner of the workpiece rests against the bar and does not move during operation.

A stop-limiter, which is placed on a workbench and fixed to the circular saw with a special bar with two flanges. Used for cutting plywood or hardboard

Miter square

A metal square, one thick side of which serves as a guide stop or limiter, and the second side of a right angle is thin, with a dimensional scale applied to it. A miter square can be used to cut an angle on a workpiece, and also as a guide bar and stop.

Aluminum alloy miter square

What is the meaning and benefit of homemade products?

Homemade trims are one-piece, even unique products. Each master makes a tool to solve his specific problems. To cut long workpieces, you can attach the trimmer to a flat beam (up to 6 m). The beam itself will work as a support (workbench) for long workpieces.

Factory trims do not make it possible to cut long workpieces unless an additional extension of the bed is built.

Sometimes there is a manual circular saw, but there is no trimmer and no money, no time to purchase it, and so on. The material for making such devices is cheap or costs nothing and is already at hand. Therefore, the question of whether to do the trim yourself or buy a factory one is decided by each master, based on the conditions.

The prices for factory trims are also taken into account:

Miter saw Makita LS1040FN 196176, power 1650 W – about 22 thousand rubles.
Makita LS1219L with broach. Power 1600 W – about 67 thousand rubles.
Budget options: Encore Corvette-8M 90080. Power 1200 W, - about 7 thousand rubles.

Advantages

When a tool (and even more so a machine) is produced independently, its design, as a rule, takes into account as much as possible the needs and tasks that are supposed to be solved with its help:

so that the molded parts do not have burrs and creases when cutting, it is necessary that the circular saw has an adjustable speed of movement relative to the plane being cut (so that the burrs are removed by the cutting edges of the saw teeth);
Suppose you need to make not the usual transverse trimming of molded products, but at a certain angle. In this case, it is necessary that the workpiece be fixed to avoid play during cutting;

It is extremely difficult to find a cross-cutting machine for sale that has the function of not only rotating the worktable, but also the option of pressing the workpiece. And if you manage to find such a tool, it will not be cheap.

and, of course, the price. A cross-cutting machine can be assembled literally from scrap materials, moreover, from parts that cannot be used anywhere else. Cost-effectiveness – why not a decisive advantage?

Pros and cons of homemade products

The homemade product makes it possible to fully use a manual circular saw, for its intended purpose and for trimming. This saves space in the workshop and money on purchasing a factory trimmer.

Disadvantages of homemade products: limited functionality, rough cutting. They are good for rough carpentry work, and less so for fine carpentry. The factory trim has degrees of adjustment for sawing at different angles in two planes. As well as other options - laser pointers, clamps, backlight. Some models are broached. There are no such opportunities on homemade products.

Trimming based on a grinder

To solve this problem, a grinder is often used. It is ideal for making your own miter machine for processing end surfaces. The homemade version will have the following technical characteristics:

What problems can a homemade design have and how to solve them?

Due to the simplicity of the design, such products have practically no problems with the frame. If a loop breaks, it can easily be replaced with another one. If a support block or plywood wall comes off, it can always be put back in place. There may be problems with the operation of the manual circular saw itself. But they can also occur without trimming. Therefore this is a separate question.

In general, making a miter saw from a circular saw is simple and it significantly helps solve various household problems, for example, accurately cutting 200-500 pieces of picket fence, blanks for boxes, pallets, etc.

About choosing a saw model

Typically, recommendations regarding choosing a power tool model come down to comparing power, functionality and similar characteristics

We will not repeat these generally correct tips, but we will draw the attention of our readers to the main thing

Therefore, we strongly advise you to first determine more precisely for what purpose and for what work the tool is being purchased, and only then choose a specific model.

A circular saw is mainly used in “manual mode”, that is, the master holds it in his hands and moves his hands along the part being cut. For comfortable and fatigue-free work, the saw should weigh as little as possible and fit comfortably in the hand.

For a miter saw that is intended to be used in a carpentry shop, the recommendation is exactly the opposite: choose a saw that is as large as possible. It is preferable to buy a saw with a broaching mechanism, which allows you to cut workpieces of significant width and diameter.

Features of sawing logs using a chainsaw

Creating additional equipment for sawing logs is quite simple:

To create a support, a frame is used, which can be created from the legs of a school desk. The most suitable pipes are with a square cross-section of 20 × 20 mm.
When constructing the frame, it is necessary to create 2 clamps and secure the crossbar at one end. This element must have holes for tie bolts. A protrusion for the tire is created in the middle.
In order to cut a log lengthwise, it is necessary to construct a support frame, the width of which must be at least 8 cm in length.
For ease of operation, a handle should be welded to the frame.
Before carrying out work, you must carefully check whether the frame is securely fastened to the tire.

Using a homemade tool is quite simple. Before sawing, you need to install 2 sawhorses - they will be used as a support for the log. In addition, a metal strip or flat board , which will serve as a guiding element.

Lightweight nozzle

Such devices are often used, but they should only be used when creating boards for fences or sheds. This is due to the fact that the attachment is secured to the tire only on one side.

Trimming based on a grinder

To solve this problem, a grinder is often used. It is ideal for making your own miter machine for processing end surfaces. The homemade version will have the following technical characteristics:

Long sawing technique

The most difficult stage of the process is making the first cut. To do this you need:

install a leading ruler, which consists of two boards that are fastened together at an angle of 90 degrees;
after this, it is necessary to place the sawn log on the supports and fix it;
then it is important to check whether the log is level;
at the next stage it is necessary to secure the leading ruler to the supports using self-tapping screws;
After this, you can start creating the first cut.

Professional equipment

Now let's talk about professional equipment. Let's consider the cross-cutting saw ZUBR ZPTP-255-1800. The tool is used for cutting wooden parts and thin-walled metal. Why combined? This is because it can be used to both trim workpieces and work like a circular machine.

Main advantages of the model:

Mobility;
Compactness;
Functionality;
Safety system.

This machine combines a crosscut and a circular saw at the same time. The adjustable head position allows for high quality cuts. The machine allows you to make longitudinal cuts at any given angle. The equipment is equipped with a locking mechanism for turning on the drive and raising the protective casing. This model has the ability to connect an industrial vacuum cleaner to keep the workplace clean.

Another good option from all the gray mass of equipment is the Makita MLT100 table miter saw.

It is used both in everyday life and in professional production in workshops and workshops. The design of the machine allows it to be moved on a special trolley and can be easily mounted in a designated place on a workbench. The sliding table allows you to work with large workpieces. The table can be rotated both to the side and forward. The long service life of this equipment is increased due to the high quality of parts and materials used during assembly.

Allows you to make cuts both vertically and at a specified angle. The high precision of cutting parts is due to the presence of clamps, guides, scales with degrees and a ruler. The equipment combines a cross-cutting machine and a circular saw at the same time.

Electric brake included. There is a connector for connecting a dust removal device, useful for large volumes of work.

Properties of finished products

narrow-profile, having a specific purpose;
models equipped with some additional functions.

Different types of saws differ in price, related to the tasks of the model and the popularity of the manufacturer. The most famous brands:

Metabo.
Bosch.
Intersko.
Makita, etc.

The crosscut type includes the following parts:

saw blade;
motor;
kickstand with start;
handle for holding and directing.

The commutator motor does not require regular monitoring and lubrication of parts, while the asynchronous motor is distinguished by long-lasting and quiet operation. There are options where the engine is mounted at the rear, which makes visibility much better when working manually.

The motor operates using a mechanism that transmits rotation through a belt or gear. In the first option, noise is reduced and there is no jitter of the cutter, and the second option does not allow the saw to slip when cutting in case of strong pressure.

How to make a crosscut from a circular saw?

So, in order to make a trim with your own hands at home, you need to make a box that will serve as a base. Chipboard (chipboard) can be used as a raw material for making the box.

In the process of knocking and assembling the box, experts recommend using confirmats consisting of 1 element - they are essentially ordinary ties for connecting wooden parts. The final box for the base for trimming should be shaped like the letter “P”.

On both sides, small pieces of chipboard need to be secured using self-tapping screws. Thanks to this manipulation, you will adjust the position of the tool sole. The next step in transforming the circular is fixing it. Moreover, this should be done using the same clamps, and you can also use wing clamps.

Next you should proceed to installing the so-called table. It should be fixed near the base of the table. However, keep in mind that in the process of carrying out this activity you reduce the depth of the cut by 1.5 centimeters, so try to place the profile as close as possible in relation to the saw element.

After carrying out the above described manipulations, you can start making a test cut - you should get a cutting line based on the stop. If this happens, then you did everything right.

As you can see, it is quite possible to make a miter tool from a circular hand saw. The main thing is to strictly follow the instructions and recommendations, as well as put in a little effort and be patient.

Types of miter saws

There are several types of miter saws (popularly called “miter saws”). Let's get acquainted with these varieties.

READ What Wood Saws Are There?

Remodeling process + (Video)

To be precise, this can hardly be called a rework; it is a refinement or expansion of the functionality of the angle grinder. You can divide the revision into stages or steps of completing the work. First, let's define the main tasks. It is necessary to make a table for installing a circular saw. It can be made of any available material, but a base made of angle steel would be preferable.

The grinder should be painlessly installed and removed, so its attachment to the table should be open and accessible. The cutting disc will be installed directly on the angle grinder shaft. It should have height adjustment or change the height of the cutting disc above the table plane.

The table should have an adjustable guide. With its help you can set the thickness of the board cut. As a special case, you can install a corner guide, if necessary.

So, we are constructively making a machine to fit the existing grinder with height adjustment of the cutting wheel. To simplify the design, we use wood:

We make a slot in the tabletop from the board for the saw. If it is a furniture board or a sheet of plywood, then it is advisable to strengthen it with an additional strip along the position of the cutting wheel;

We attach the rear part of the machine structure to a hinge. Then we fix the grinder. To secure it you will need a short bolt with a lock nut. The bolt will be screwed in instead of the handle and secure the angle grinder to the hinged part of the machine;

From the side of the grinder handle we make a clamp with a sawn-through adjustment bar. This is a U-shaped bracket into which the drill handle should fit tightly. For density, you can glue rubber strips. An adjustment strip with a cut will be attached to the same U-shaped plate.

We fix the hinge and the adjusting bar from below to the tabletop so that the cutting wheel fits evenly into the cut of the tabletop;

We install the tabletop on a base made of steel angle or wooden blocks;

We supply electricity. Electrical safety conditions must be met. It is better to connect using a cable that is not afraid of a piece of board accidentally falling on it;

We do a test run. The saw blade should rotate without catching the edges of the slot. If this is not the case, then you need to change the position of the hinge or U-shaped plate. The supply of material to the cutting wheel should not cause displacement or vibration of the grinder.

Both the grinder and the manual circular saw are very successful removable drives for a stationary circular saw.

It’s easy to make a hand-held circular saw from a grinder. To do this, you need to remake the protective cover so that almost the entire saw blade is covered. And on the working sector of the disk it is necessary to install a movable protection that will move during operation. It is also advisable to install a nozzle for a vacuum cleaner on the casing if the saw will be used indoors.

In the front part it is necessary to install an additional curved handle made of a thin-walled pipe. With this handle it will be more reliable and safer to fix the position of the circular saw during operation.
