Stationary circular saw - DIY production. How to make a circular saw with your own hands Homemade circular saw

Stationary type circular saws are quite expensive on the market. However, if you wish, you can make the model yourself. To do this you will need a standard set of tools. A welding machine is used to install the frame. To fix the saw blade, you will need a drill. Before assembling the device, it should be taken into account that the design of circular saws can vary greatly.

Hand saw model

(stationary) made with your own hands is quite simple. First of all, you need to assemble the table. Metal profiles are used for this. The ends of the workpieces are connected using a welding inverter. The saw blade is directly attached to the holder. A simple stationary circular saw made from a manual one is assembled with a small-width pulley.

In some cases, a casing is used to protect the device. The support for a circular saw is often of the rack type. Modifications with cam quills are very rare. Commutator motors are installed with a power of 3.3 kW. In this case, it is more expedient to make the platform from a steel sheet.

Washing machine devices

It is quite easy to assemble (stationary) with your own hands from a washing machine. A motor is used for this purpose. It is recommended to select a diameter up to 30 cm. The pin is used with a crank drive. Many experts recommend installing guides up to 33 cm long. The working plate is placed on the front of the frame. In this case, the feed mechanism does not need to be installed. To secure the frame, a metal corner is used. The flange is most often installed behind the caliper. At the end of the work, it is important to fix the flywheel.

Modifications with one stop

Very often, specialists assemble a circular saw with their own hands. You can find a wide variety of drawings for designs with one stop. Many of them involve the use of cam rests. Experts first recommend starting assembly with the frame. The legs in this case can be made from wooden blocks.

After installing the working plate, guides are installed. A horizontal shaft must be secured above them. A corner is attached to the edge of the platform, and the casing is rarely used in the design. There are also many models with a power rest. They are large in size. The bearing row is usually installed above the working plate. In some cases, the support is welded near the pin.

Models with multiple stops

With several stops, it is quite difficult to assemble a circular saw with your own hands. The modification drawings indicate the need for a guide pin. Assembly of the model begins with a frame blank. For this purpose, profiles are selected from stainless steel. It is also important to note that the stands can be fixed using a welding inverter.

The work plates are installed last. Sometimes a circular saw (stationary) is made with your own hands with a 3 kW commutator motor. A flywheel is used to adjust the position of the steady rest. In this case, the bed must be fixed on racks. A caliper is used to change the position of the platform.

Drawings of a crank ratchet device

A stationary circular saw is made with a cranked ratchet with your own hands (photo shown below) using a rack and pinion support. In some cases, a feed mechanism is used. First of all, during assembly, it is important to install the lower frame. For this purpose, two stainless steel profiles are selected. To install the bearing row, you will need a welding inverter.

It is also used to connect workbench guides. The pin is installed only with a cross member. It is soldered on the edge of the table. At this stage of assembly it is important to calculate the distance to the saw blade. On average it is 22 cm. A wooden fence is used to protect hands. It is important to fix the guides behind the counter. The steady rest is most often installed behind the flange. In order for the flywheel to rotate freely, a small lining is required. It is fixed behind the guides.

It is also important to note that modifications without a caliper are very common. Their pins are used with gearboxes. To protect your hands, a small shield is installed. The bed is most often used with sharpened ends. The lunette in the design is fixed on the platform. If we consider simple models, then guides can be used from wood. The commutator motor is used for both 3 and 5 kW. The work of assembling the saw ends with the installation of stops.

Dimensions of saws with two steady rests

With two steady rests, it is very easy to assemble a circular saw (stationary) with your own hands. The dimensions of the table in this case depend on the diameter of the saw blade. The width of the platform, as a rule, does not exceed 35 cm. In order to assemble the modification, the bed is first installed. Metal profiles are selected at 3.4 cm. The pins are mainly installed behind the steady rests.

In some cases, the beds are placed on two stops. The quill is used with a worm gear. If we consider large-sized modifications, they use wide racks. It is also important to note that it is more advisable to install the lower block at 56 cm. To adjust the steady rest, a rotary handwheel is used. The saw blade is placed directly behind the caliper.

Modifications of the TS 820 series

You can make a saw of this series yourself. For this purpose, the frame is installed with a width of 34 cm. The corner for the stop is easiest to make from a metal profile. The bearing row is attached to the stand with screws. Many experts advise installing the steady rest last. The guides for the saw are selected at 34 cm.

The easiest way to make a tool rest is from a wide block. The commutator motor is installed on the saw with a power of 3 kW. The gearbox is attached to a stand on the platform. The saw blade is fixed to the drive shaft. For normal operation of the modification, the caliper must be firmly fixed. Barriers can be used to protect your hands.

How to make a model like TS 825?

If you have the tools, you can easily make this stationary circular saw with your own hands. A wide variety of drawings for this design can be found. However, the most common are two-rest circuits. The bearing row in this case is installed behind the cross member. Not a lot of power is selected. The pulley should be installed in the central part of the working platform.

In this case, a feed mechanism is not required. A metal corner is used to fix the plate. Saw guides are used at low heights. For free movement of the steady rest, a flywheel with a rotating mechanism is used. The bottom block must be well protected. It is also important to pay special attention to the installation of the bed. The legs for the structure can be made from ordinary bars. The saw blade itself is placed near the central post.

Assembly of the GKS 190 series device

This circular saw (stationary) is assembled with your own hands only using a 4 kW commutator motor. The bearing row can be installed behind the rack. A small flywheel is used for this purpose. It is also important to note that the pulley is allowed to be used at 5.6 cm. The gearbox is most often installed behind the steady rest. All this is necessary for free rotation of the shaft. In this case, the bed is easiest to make from bars. It is more advisable to select racks of small width.

The flange is usually installed at the edge of the platform. In this case, the drive shaft should not come into contact with the guides. The barrier tape is most often mounted behind the A-pillar. The width of the platform should not exceed 68 cm. The easiest way to install the shield is with screws. However, it must be at a safe distance from the gearbox. Particular attention should be paid to the lower supports. To increase stabilization, it is recommended to use only wide profiles. The height of the caliper in this case should not exceed 30 cm.

Modifications of the GKS 156 series

This circular saw (stationary) is difficult to assemble with your own hands. First of all, it is important to note that a 4 kW motor will be required. In this case, many experts advise using only steel guides. They should be installed behind the front pillar. The tool rest is most often made from a block. It is also important to note that the design will require a wide stop.

It is more appropriate to install the shield near the rear support. The bearing row is mounted together with the stand. At this stage of work, it is important to calculate the exact distance to the saw blade. The minimum gap allowed is 3 cm. The frame is most often used with four legs. To install the guides, a welding inverter is used. The lower block is mounted under the gearbox. It is important to securely fix the rest, and in this case a ratchet is not required.

How to make a model like GKS 144?

The specified circular saw (stationary) is assembled with your own hands on a motor with a power of 2.2 kW, and the bed is selected at 40 cm. The bearing row is fixed in the front part of the stand. It is easiest to use guides that are small in width. It is also important to note that one flywheel will be required to assemble the device. It must be attached to the rotating mechanism. It is more expedient to make the shield from a steel sheet. In this case, a casing is not required. The legs themselves can be installed around the corner. The steady rest for the saw is not very wide. The carrier plate is fixed last.

Assembly of the K-CS 1300 series device

This circular saw (stationary) is quite easy to assemble with your own hands. The bed for the model is used at 34 cm. In this case, the bearing row is installed behind the stand. The saw blade is placed directly after fixing the guides. Particular attention should be paid to the commutator motor. In this case, its power must be at least 4 kW.

The flange is used with a steel cover. It is more advisable to install the hand rest behind the front pillar. For this purpose, two holes are made on the working platform. It is important to fix the steady near the motor. There is no need to install a saw blade guard. The lower block should be immediately selected not of great height. It is more expedient to use the caliper with a roller mechanism.

Modifications of the K-CS 1325 series

The devices of this series are assembled using 3 kW commutator motors. According to experts, it is better to use wooden handholds. It is also important to note that the support should be installed on top of the workpiece. In this case, the ratchet is not installed on the saw. The gearbox is used with one bracket.

Reading time ≈ 4 minutes

A circular saw is used to cut wood and plastic. Its cutting base is a flat metal disc with a serrated outer edge. When choosing such a tool, everyone decides for themselves what type they need: tabletop, manual, stationary. Many people prefer the manual option. However, in some situations it is necessary to secure the saw. In this case, you can make a table for a circular saw with your own hands, having the opportunity to secure the tool if necessary.

Preparation of tools and materials

Having decided to make a table for a hand-held circular saw yourself, you need to make sure that you have all the materials necessary for the work:

laminated plywood (9 or 11 mm), size 800 mm by 800 mm;
16 mm laminated chipboard or other sheet material suitable for making the body, sheet size 400 by 784 mm - 4 pieces;
bars 40 by 40 mm (length depends on installation method);
self-tapping screws;
bolts.

Any hand-held circular saw will work for this table. It must be remembered that when attached to a table, the cutting depth decreases by 10-20 mm. So saws with small blades are not suitable for such a table.

Step-by-step instructions for assembling a table for a circular saw

1. Manufacturing of the body. Sheet material for the body is cut to size: 400 mm by 800 mm. The parts are fastened using self-tapping screws and bars. It is better to carry out the assembly by first drilling out the external parts of the box. The result is a rectangular box without a bottom or lid. The upper part of the bars is subsequently used to secure the plywood sheet.

2. Preparing and securing the plywood top. Hole slot. First, a piece 800 mm by 80 mm is cut out of a sheet of plywood. Next, measurements are taken of the support shoe of the saw that will be mounted on the tabletop. Markings are made on the back side of the plywood. 2 central axles will be required. Without them, it is impossible to make accurate markings. Then marks are applied to the plywood corresponding to the dimensions of the support shoe. Then they take the measurements that the circular has: the diameter of the lower protective casing, its thickness, the maximum distance from the edges of the support shoe. In accordance with the obtained dimensions, place marks and cut out a rectangular hole using a jigsaw.

3. Attaching the saw to the plywood table top. First, 4 holes are made in the shoe. Diameter - 10 mm. Next, install the tool so that the working part fits into the cut hole. When the saw is level, you need to mark the location of the holes. Marks are made in the central part. In order for the tool to stand securely, you will need plowshare bolts with a countersunk conical head (M8) for fastening. To install them, you will have to take care of the high-quality recess of the cap; it can protrude by a maximum of 1 mm when not tightened.

The plywood is drilled from the outside, the diameter of the resulting holes should be 8 mm, and then a countersink should be made for the head. When the holes are ready, the saw itself is installed on the cutting table for the circular saw, the bolts are tightened from the inside using nuts with plastic locks or spring washers.

4. Fastening the tabletop to the body. Start button. First, holes are made at a distance of 30 mm in the corners of the plywood table top. Then a hole is drilled in the central part of the bars. The parts are connected using an M8 18 mm steel fitting. The usual “Start-start” button is installed on the side. An electrical network is laid inside the case, and the button on the instrument itself is pressed.

5. Manufacturing of a thrust beam. A simple table for a circular saw will become much more convenient if you equip it with a stop beam. The drawings contain all the necessary dimensions. The beam can be made from plywood and secured using full extension furniture rails. The resulting beam should slide above the surface at an angle of 90° to the cutting plane with a slight gap.

6. Stop for longitudinal cuts. It is made from aluminum cornice. 150 mm from the edges, first drill holes for the bolts, and then draw 2 lines from the place where the bolts are attached to the center line. At the intersection and further towards the bolts, 12 mm holes are made at a distance of 30 mm. The bolts from below are tightened with nuts. And along the drawn lines they make slits in the tonic; their width can be seen in the photo.

It is difficult to cope with repairs, construction or gardening work without a circular saw. Alas, working with a manual device is not always comfortable, and buying an expensive machine is impossible for obvious reasons.

Talented craftsmen are able to solve this problem by making a homemade circular machine with their own hands. What tools and materials are needed for this? What to consider before starting work? How to extend the service life of the received product? First things first.

Requirements for a homemade circular saw

Contrary to misconception, to make the device you will need ordinary lumber and tools. But before thinking through the design, you need to think about the bed - the element on which the machine will be installed.

The main requirements for it are reliability and stability. Typically, a welded metal structure is used for production processes, but it will not work for domestic needs. Since a tabletop circular saw for wood will not cut the most voluminous materials, it does not require the most powerful engine, and the bed can be made of wood. There is no need for additional fixation (mounting in concrete), and possible vibration during operation will be reduced to a minimum.

The second requirement is the selection of the optimal power of sawing equipment.

Otherwise, the installation will not be justified, and a lot of electricity will be required to operate the machine.

Also, when developing a circular machine project, it is necessary to take into account the following equipment parameters:

It is better to place the buttons on the outside of the circular saw or provide an opening tabletop for them.

Now - a few words about the main design elements for small household work.

Machine components

In addition to the bed, an important element is the power unit. Some experts advise installing factory hand saws, but their power is not always comparable to that of real machines. In addition, you can make a mistake with the disk size. Therefore, it is better to assemble the power unit from two parts - the engine and the shaft for the disk.

An arbitrary asynchronous type power plant operating from a 220 V network is suitable as the first one. Its power does not exceed 1200 W, and the rotation speed is up to 4-4.5 thousand rpm. It is better to take standard pulleys for mounting the cutting element on the shaft, which have a tension system for reliable fixation and transmission of torque.

You will also need to do:

support bar (a workpiece length limiter that can move relative to the plane of the saw element; makes it possible for the user to adjust the width);
table top;
legs (requires timber with a section of 30x30 or 40x40 mm).

When selecting the height of the table legs, the user's height is taken into account. The tabletop parameters are selected in the same way.

If long workpieces are to be sawed on a circular saw, more legs will be needed, otherwise the structure will begin to vibrate.

Suitable tabletop material is thick plywood of at least 50 mm, plexiglass or fiberglass. Chipboard is not recommended - it is not very reliable and can crumble during operation.

Tools and materials

In order to summarize what has been said above, a complete list of required materials is provided below:

sheet of plywood/plexiglass/textolite;
boards 50x100 mm;
wooden bars;
steel corner for guides (preferably);
a pair of clamps;
hand circular saw.

Motors from washing machines, angle grinders, and drills can be useful for manufacturing. However, their service life may be nearing the end, so they will not be suitable for a stable functioning machine.

An old kitchen table can serve as a tabletop, but it is better to assemble the frame yourself.

Before starting work, check that you have the following tools:

screwdriver or drill;
hacksaw/jigsaw;
tape measure and pencil.

Now it's time to start producing the machine

Stages of work

We have examined the main design features, we have stocked up on the necessary tools, it’s time to get down to business and understand how to make a circular saw with your own hands so that it becomes a reliable assistant in any construction matters.

Making a countertop

Marking and sawing out the table top. Based on the dimensions of the parts that will be processed on the machine, a sheet of plywood is cut out with a jigsaw. After this, it is rubbed down with sandpaper. On the underside of the tabletop, a place is marked for the slot of the circular disk. The dimensions of the sole of the unit are also measured by applying it from the outside; To do this, remove the blade from the saw and trace the required part, thus determining the seat.

Planting bars are chosen to a depth of approximately 10 mm (depending on the size of the disk). Then the saw is tried on; if there is not enough space, the hole is deepened.

Installation of slats. It is better to place transverse and longitudinal slats on the wrong side of the tabletop. The planks themselves, in the amount of 4 pieces (a pair of each) are made of timber.

For transverse ones, the length should be 7-8 cm less than the width of the tabletop on each side.

The slats are attached to self-tapping screws, for which nests are pre-made. The fastener is fixed so that its head does not protrude above the tabletop.

Check that each side of the surface extends 7-8 cm beyond the edges of the resulting frame.

Final fixation of elements. First, the transverse ribs are attached. The edges of the slats are lubricated with wood glue for maximum strength. Next, the structure is fixed with clamps and self-tapping screws are screwed in. When the glue is completely dry, the same is done with the longitudinal slats. Then the parts of the frame are tightened together with two fasteners on each side. The clamps are removed.

Making legs

After selecting the bars, the following actions are performed:

Marking and cutting out the workpiece. The height of the legs (length of the beam) should be such that it is convenient to work. Typically the tabletop is located at hip level; this must be taken into account.

Adjusting the angle of inclination of the supports. At the bottom of each support, a portion of the material must be planed so that the leg is positioned at an angle. The area of the base should be less than the area of the top (the junction with the tabletop).

Fixation of legs. It is recommended to use steel corners, installed by surprise, to give the structure additional rigidity and stability. The fasteners are bolts with washers; they are fixed with the head facing outward so that you do not get injured while working on them.

Screed supports. Another operation to give greater stability. In pairs, fasten the legs diagonally on each side of the frame.

In this basically simple way, you can make a high-quality circular saw for wood with your own hands in little time and money.

Safe work on the table saw

Homemade cutting or sawing equipment requires a special approach to work. The following safety precautions will help you avoid injury.

Sawing workpieces with knots, cuttings, or icing is undesirable, and with metal inclusions is prohibited.
When sawing wood longer than 2 m, stands or support frames are used. To receive the sawn material, the assistance of one person from the opposite side will be required.
The workpiece is fed smoothly, without pressure or sudden movements. Otherwise, the disc may break or get stuck in the wood.
You cannot push the remaining part of the small-sized material with your finger - there are special pushers for this.
Cleaning the work surface is done with brushes, but not with your hands.
It is mandatory to use glasses, long sleeves, and, if necessary, a respirator.
The saw blade can only be replaced when the machine is switched off.
Regularly remove shavings, sawdust or other waste from the work area.
Monitor the condition of the teeth of the working element. If they are misaligned, the disc should be changed or the teeth sharpened. Otherwise, the gap under the disk may increase, and the operation of the equipment will again become dangerous.

Even a novice craftsman can cope with the manufacture of a homemade circular saw for wood, if he foresee in advance the important aspects of the future design. During the production of the unit, ensure compliance with the dimensions, reliability of fastenings, and stability of the elements. In order for the equipment to serve for a long time, it is worth following the operating requirements for hand-held circular saws. The above recommendations will help extend the life of the installation.

A stationary circular saw, made with your own hands, is a useful and necessary tool in the household, which greatly facilitates the woodworking process. In order to make a circular saw with your own hands, you need to have the necessary tools and materials on hand, as well as be able to work with metal and know welding.

Required tools and materials

A homemade circular saw at home can be made in two different design options: stationary and desktop installation. These installations differ from each other only in the height of the frame used in the design of the unit. The choice of bed height for the device depends on the frequency of operation of the installation and the desire of the master. If the saw is rarely used, then it can be made into a tabletop version. This design is convenient because, if necessary, the device can be quickly dismantled and free space can be freed up. If you plan to use the unit frequently, it is recommended to make a stationary installation option yourself.

The design of a stationary installation includes several components, the main ones of which are a table, a saw blade, an electric drive, an adjustable stop and a shaft.

To construct the device you will need the following materials and tools:

sheet metal with a thickness of at least 8 mm;
metal corner measuring 45x45 mm;
electric drive;
ball bearings;
manual welding machine;
wood block;
a piece of plastic or laminate.

The process of manufacturing a circular saw is greatly facilitated if you make an installation drawing in advance.

All installation parameters should be indicated on the drawing. All elements of the unit are manufactured in strict accordance with the previously developed drawing. After all structural elements have been manufactured, the unit is assembled using a welder.

Technology for assembling a stationary installation of a circular saw

The main part of a homemade circular is the table. The tabletop of this structural element is made using sheet metal. The size of the tabletop depends entirely on the desires and preferences of the master. The main requirements for the table are to ensure reliable stability and ease of use with the tool. If installation of additional equipment is required, the places for its installation can be covered with a sheet of plywood.

When designing and assembling a homemade installation, special attention should be paid to the height of the guide. The most convenient design option is considered to be one in which the guide protrudes above the table surface by 120 mm. At this height, it is possible to process the board both in width and thickness.

When constructing a guide for installation, it is necessary to use two pieces of metal angle and a clamp that is attached to them using hand welding. Making the guide from two pieces of angle helps prevent it from moving while working on the installation. A wooden beam and a strip of laminate are attached to the corners using self-tapping screws. The length of the piece of laminate should match the length of the table.

When making a circular saw, the table should be made adjustable in height, which will make the work process more convenient.

To mount the electric drive and the installation shaft, a single platform should be made. The platform is installed on one axis in the form of a rocker arm. The platform is fixed using a bolt with a diameter of 15 mm.

A metal plate in which a hole needs to be made is fixed by welding to the side of the saw. It should be oblong in shape along the direction of the rocker. A wing with handles is screwed onto the bolt passing through this hole; it acts as a lock. When using a 400 mm disc in this design, it is possible to process boards up to 240 mm wide.

Other circular saw design options

A mini circular saw can be made manually. When constructing such a saw, it is best to use a grinder. To achieve this, some changes and improvements are made to the design of the tool. An axial handle and a sliding stop should be mounted on the tool body.

To construct the stop, you will need two metal corners. The corners are placed on the sides of the saw disk working element, which replaces the disk working element made of abrasive material used on the grinder. The corners are fastened while maintaining a gap of 3-4 mm. The corners at the front and rear are connected with bolts and nuts. To maintain the gap, washers are used. The lower edge used in the stop of the corners is rounded, which prevents snagging on the workpieces being processed.

To secure the stop, a clamp is attached to the body of the angle grinder. This structural element is made of metal tape. The screed should be placed at the bottom. A strip of galvanized steel with a thickness of at least 1.5 mm is attached to the tape. A hole is made in the strip for the sliding stop bolt. Using washers, the required gap is established between the working element and the side part of the stop. The gap should be the same on both sides.

An axial handle is attached to the device body. For this purpose, the gearbox is disassembled. This is required in order to decide in which places four holes can be made for small bolts. The handle should be made from a piece of pipe. The handle should be shaped like a bracket, and holes should be made at the ends of the bracket for the mounting bolts. Under the handle you need to secure a piece of rod protruding forward. Make a hole on the rod for an axle 4-6 mm thick. For ease of use of the device, the gap between the rod and the handle should be at least 100-150 mm.

Then the control rod is made. To construct this element of the device, you will need a rod with a diameter of 4-6 mm. The end of the rod is flared, and with the help of washers on the front mount of the stop, the same gap is set along the entire length. The section of the rod that fits into the hole in the handle is equipped with a thread. A nut is screwed onto the rod, and then the rod is secured with a second nut. The kerf is adjusted using nuts.

A DIY circular saw is an excellent way to save a lot of money and at the same time acquire fairly high-quality and reliable equipment. A properly assembled homemade circular saw is in no way inferior to a factory saw and is also capable of sawing logs of even very large diameters.

A circular saw is used for straight cutting of lumber.

How to make a homemade circular saw?

In order for the circular saw to easily cut large logs, it is necessary to equip it with a truly powerful electric drive. In addition, for this purpose, a belt drive, a shaft and a motor with high traction force are installed on it. All hand-made circular saws consist of two parts: upper and lower.

At the bottom there is always various electrical equipment, namely:

saw motor;
transformer;
device that starts the circular machine.

At the top of the circular saw install:

pulley;
cutting disc.

Large homemade circular saw

When making a frame for the top of the saw, it is best to use a metal corner 25 mm wide. In this case, the rectangle, which will represent the frame of the upper part of the homemade circular, should have dimensions of 600x400 mm. Next, four pipes are welded in the corners of this quadrangle, the diameter of which should be 17 mm and the height should be approximately 2.2 m.

After this, it is necessary to strengthen two corners on the frame, on which the bearings will later be fixed. The distance between these corners directly depends on the length of the shaft. To fix bearings, as a rule, clamps are used. It is best if the bearings installed on a homemade circular are closed. This way you won’t have to worry about wood chips getting into the space between the balls, rings and separator. Don't forget to also cut a thread at the very end of the shaft so that you can install a cutting blade on it later.

The lower part of the circular saw should be made much more massive, which will provide it with the necessary stability and reliability. Therefore, when making the lower frame, you need to take a corner with a width of at least 40 mm. Next, across the frame it is necessary to secure two additional corners, which will later support the motor of the homemade circular saw. The most suitable motor for a DIY circular saw is an asynchronous three-phase motor with a power of at least 1.5 kW and 1500 rpm. The pulley groove should be quite large, approximately 80 mm, and it should be mounted directly on the shaft itself. In addition, you will need to weld a fairly small metal platform to the frame on which the starting device will be placed. Large pipes 2.2 m long, which you previously welded in the corners of the frame, are necessary for high-quality tension of the belt so that the metal wings press the thin pipes.

Now you need to insert both the lower and upper parts of the homemade saw into the finished supports made of pipes, and then tighten and tighten the belt with metal wings. You can start the motor in this model of circular machine yourself using starting capacitors. In order to additionally load the motor and increase its torque, you can use a 220/36,400 W transformer.

Pendulum circular saw with electric motor

You can make a homemade circular saw quite easily to cut logs and pieces of wood, the thickness of which corresponds to the strength of the electric drive installed on it. If you intend to work with large and very thick pieces of wood, then you should equip your homemade saw with a truly powerful electric motor, as well as install a shaft and belt drive on it. The best solution in this case would be to install a special pendulum frame.

When making a pendulum circular with your own hands, only very strong steel corners should be used as the material for the frame. Next, on the finished steel frame you will need to place all the mechanisms necessary for the normal operation of a homemade circular saw. With this design, you can personally set the flight altitude of the cutting blade without any special effort, while avoiding excessive design difficulties.

Mini-circular base

To make such homemade products you will need:

two metal plates;
wooden beam;
spindle from a bicycle;
star;
chain.

The mini-circular saw should be placed on a strong and stable table, since any rocking can pose a danger to human health and also interfere with normal operation of the saw. Before you start making a machine from a hand-held circular saw, you need to make a special table. In this case, you can use metal sawhorses and a regular old kitchen table as a bed. To begin, you will need to connect the trestles to each other with a wide wooden board at least 50 mm thick, and then secure the kitchen table to this base.

You can make the tabletop itself from two metal (preferably steel) plates with a cross-section of about 4 mm. In addition, you can use thick wooden blocks for this purpose.

It is important not to forget to leave a small gap between the metal sheets, the size of which is usually 10-12 mm.

In this case, you need to make sure that the edges of the metal plates are perfectly parallel to each other. Now that the table is completely ready, you can begin attaching the circular saw itself to it. It is important to note that it should be secured from below, and in such a way that its cutting disk is directly in the gap between the two sheets of the tabletop.
