DIY circular saw diagram. DIY circular machine

Today you can quite often find homemade circular saws. A circular saw can be made with your own hands if the craftsman has at least minimal skills in working with metal. To make the structure you will also need some equipment. All work must be done carefully.

Figure 1. Schematic of a stationary circular saw.

It is advisable to make such a device yourself if any of the following materials are available: pieces of steel angle, rectangular profile pipe, engine or grinder. If you don’t have a motor, you can purchase one at the construction market.

Manual circular design

You can easily make a manual circular saw with your own hands if you have a grinder available. You will need to do the following simple devices: sliding stop and axis handle.

Required parts:

  1. Metal corner.
  2. Washers.
  3. Bolts.
  4. Nuts.
  5. A strip of metal.
  6. Bulgarian.
  7. Metal pipe or rod.

Making the stop and preparing the necessary holes

The sliding stop is made of several pieces of small metal angle, which are located on both sides of the working element. It is worth noting that the working element is a disk with teeth, which is used instead of an abrasive wheel. The gap on each side should be approximately 3-4 mm. The horizontal edges of the corners will need to be rounded at the bottom so that they do not cling to the workpiece being cut. The corners will need to be connected with cross braces at the front and back. To do this, it is best to use bolts and nuts; a gap can be made by using a pack of washers.

You will need to put a metal strip clamp on the tool body. The screw tie of the clamp should be located at the bottom of the structure. You will need to rigidly fasten a double-folded strip of tin or galvanized steel with a hole for the rear stop bolt for sliding. The stop must be secured to the rear of the structure. The clamp with the rear thrust post can form a single structure, but the thickness of the metal strip in this case should be approximately 1-1.5 mm. By moving the washers that provide clearance, you can achieve equal gaps between the working element and the side parts of the stop.

In the tool gearbox housing you will need to drill 2-4 threaded holes for small fasteners. The first step is to disassemble the gearbox and identify places where it is possible to drill. The holes are intended to make it possible to fix a homemade axial handle. If a standard side handle of an angle grinder is used, then making an even cut will be quite difficult even for a master with extensive experience.

Making a handle and adjusting rod

The axial handle is made of a pipe or rod in the form of a horn, which is directed upward. In this case, a transverse bracket of small width can be used. The ends with which it will be attached to the gearbox do not need to be spilled. In these parts you will need to drill holes for fasteners. If the fastening ends spill, the handle will bend from the effort during operation.

If the handle has the shape of a horn, then its far part must be splashed in a horizontal plane and a hole drilled in it for an axis of 4-5 mm with a margin. If the handle is a bracket, then in the holes located in the gearbox you will need to install a piece of rod or tube sticking forward. The end of the element needs to be splashed and a hole drilled in it. There should be a small distance between the rod and the bracket - approximately 100 mm.

Next, you will need to take a piece of 4-5 mm steel rod, which will be used as an adjustment rod. One part of it needs to be bent in the form of a loop, slightly splashed and a hole drilled for the front thrust bolt. By placing washers on the front of the stop, you need to achieve a uniform gap width along the entire length of the structure. If you use a 6 mm rod, you will need to prepare several washers of small thickness.

The back of the rod needs to be threaded. The element will fit into the hole on the handle. You need to first screw one nut onto it, and upon completion of assembly - the second. You will need to loosen and tighten the nuts one by one to be able to adjust the cutting depth. On at this stage the manual circular saw will be ready for use.

Tabletop small circular

A manual circular saw can easily be converted into a small tabletop design.

To do this, you need to make a U-shaped frame from a 15-20 mm pipe or rod and attach a lever. The lower part of the bed must be bent along the cutting direction until horizontal, and then secured to the table with self-tapping screws. To make the structure stable, you can additionally install slopes.

You will need to put a rotating lever made of a T-shaped pipe on the horizontal cross member.

The transverse part of the element will need to be cut into two parts. After the structure is installed, the elements will need to be secured with clamps. To the end of the vertical part, you need to tighten the hand saw that was made with a clamp.

A similar design can also be used as a cutting device, for which you will need to install a standard cutting wheel in the grinder. However, in this case, the thickness of the cut will not exceed 70-80 mm, everything will depend on the diameter of the working element. To be able to process thick lumber, you will need a full-fledged circular saw.

Full-fledged stationary circular saw

You can make circulars of this type only if you have a design diagram. The difference between a stationary and tabletop circular saw is the height of the bed. A design diagram of this type is shown in Fig. 1.

The first element to be made is the table. It is covered with tin or galvanized sheet. The wood will rub against the wood or plastic, causing a small dent to appear. In this case, it will not be possible to make a high-quality cut. The transverse connections of the table are made from a metal corner of 70-80 mm.

The working element should not protrude above the base of the table by more than 1/3 of the diameter - otherwise the saw will be dangerous. Therefore, if you need to cut a 100 mm beam, then the diameter of the disc should be 350 mm or more. To drive such a disk, a motor with a power of 1 kW or more is required.

The first thing you need to do is compare the power of the purchased engine with your personal needs. For workpieces 150 mm or more, making a circular saw yourself is quite difficult.

A high-quality adjustable stop can be made from a piece of angle 70-80 mm, its length should be 350-400 mm longer table. One of the shelves will need to be cut on both sides so that the remainder is equal to the length of the table. The back parts need to be curved down. In the lower shelves you will need to drill holes for the threads of fasteners. After this, you will need to put the stop on the table and secure it in the required position with bolts. The stop is set according to a template that is placed between it and the tool disk.

You will need to use ball bearings, which are self-installed. Trunnions with bearings must have covers that can protect them from sawdust.

It is recommended to use a V-belt drive. The engine will fit from an old washing machine. Capacitors can be paper or oil-paper. Other elements will not be able to withstand the reactive power that circulates in the chain.

Making a circular saw yourself is quite simple if you know the technology and have all the necessary elements available.

In the household, a circular saw always comes in handy. Major repairs are a costly and troublesome task. Not everyone can afford to buy expensive tools for processing wooden materials. A DIY circular saw allows you to carry out safe work and speed up the construction process. A saw made by yourself has a number of advantages, such as reliability, efficiency and sharpening for immediate needs.

A circular saw

Purpose of a circular saw

Before you begin assembling the machine, you need to clearly define its purpose. For preparing firewood and simply cutting large pieces of wood, a firmly fixed table with a slot for a saw is sufficient. This type is common in villages and rural areas; the machines are not safe and have increased functionality.

For a more varied range of carpentry jobs, you will need a better option. The circular machine must be equipped with a coordinate table with special guides, this allows you to change the degree. The manufacture of small-sized products requires increased safety. Speed ​​control is installed and discs can be changed.

Design features of a circular machine

Circulars of any fixed type consist of main parts.

  1. Table for connecting mechanisms. An assembly combined with higher power engines is preferable to a table made entirely of metal. The surface of the table must be made level with your own hands, for a higher quality product at the end.
  2. The engine in most cases is used from what is in stock. Electric motors designed for long-term operation from the network will be preferable to commutator drives.
  3. The shaft is the most critical component of the circular. Finished products are used most often; in other cases, the assembly is made on lathe. It is important to calculate the mounting holes and eliminate runout.

A table for a DIY table saw can be used as a cutting machine. The cut cannot reach more than 8 cm, so larger jobs will require the use of a larger machine.

Stationary machine with your own hands

To perform everyday or one-time tasks, a hand-made circular saw is quite suitable. Small-volume sawing work does not imply heavy loads on the disk drive. The compact tool has small dimensions, which makes it possible to put it away after finishing work in a certain place. An experienced carpenter will need to make a large stationary type circular saw.

Making a stationary circular saw with your own hands will require precision and literacy from the master. Drawings presented in many types of literature will help in manufacturing. It is worthwhile to treat every component of the unit competently and carefully, because the circular machine is used at high speeds with a cutting tool.

Circulation table

Saw blade

The design of a DIY circular saw must contain a saw blade. The working surface of the disk is set to one third of the total diameter. For example, with a diameter of 210 mm, the disk should protrude 70 mm from the table. Parts with greater thickness will require a powerful motor, from 1 kW. A miniature circular saw will not cope with such tasks.

The splitting knife installed on some models serves to prevent short circuits and jamming during operation. It is located at the back a few millimeters from the teeth of the saw blade. The device may also be needed when making a circular saw with your own hands.

Adjustable side support

Any type of work will require a stop. The side support is made of a block of dense wood. In other cases, it is possible to make it from a metal corner. The arrangement should be slightly longer than the table structure. The stop is installed using bolts. The template is installed between the table and the cutter for precise installation and better settings.

Shaft

Homemade shaft

The most important part of the design is the shaft mounted on the circular saw. A self-made shaft for a circular saw can damage the structure and cause injury. The reason for this is runout, which cannot be avoided when making a shaft using artisanal methods. The manufacture of the shaft should be entrusted to a specialist with good turning equipment. You should remember that there is a cutter that needs a seat. The holes must be symmetrically machined and machined.

Finished shafts are sold in specialized markets. Preference should be given to parts with a self-aligning bearing. Otherwise, the conventional mechanism may soon render the circular machine unusable.

Broadcast

There are several types of gears that can be used in the design of a DIY circular saw:

  • V-belt transmission;
  • mechanism consisting of gears.

The preferred option is to use a belt drive. Using a mechanism with gears can lead to jamming if a foreign body enters and injury to the worker. When choosing the pulley diameter, the maximum number of revolutions of the saw blade is taken into account.

Motor

In most cases, homemade machines are equipped with an engine from an old washing machine. The main features are increased service life and efficiency. The speed of such engines is not high, which makes working on a circular saw assembled with your own hands safer, longer, and has a positive effect on the result. The use of a special three-phase motor implies the presence of a 380 Volt network. If one is not available, you will have to use a starting and running capacitor, which leads to additional costs.

Circular saw from a grinder or circular saw

When working with small workpieces, it is enough to get by with a small circular saw. A circular saw is made with your own hands from available power tools; you will need a grinder or a circular saw.

There are many options for stationary use of improvised tools. It is enough to secure the device from the bottom of the table to access the material to the disk. The height is adjustable depending on the workpiece, but for safety reasons should not exceed one third of the size of the saw blade. This installation option is not available for the switch; it is necessary to modify the device for convenient operation.

A fairly common option is to use a frame on guides. The simple design allows you to use the tool to work at any angle. It consists of two parallel metal pipes or angles on which the saw is mounted.

A hand-made circular saw makes the work you do faster and more economical. Such a device will be needed during major repairs and other actions related to cutting wood. The simplicity of the design, the possibility of using scrap materials, makes the cost almost zero, and making it yourself allows you to add the necessary functionality for the job.

How to make wood cross-cutting machines with your own hands DIY disc sawmill

It is not difficult to make a table for a circular table with your own hands, having at your disposal a hand-held power tool from Bosch or another leading manufacturer. But the presence of a table will significantly expand the capabilities of the tool. Manual models of Bosch circular saws, like their analogues, demonstrate high performance. But maneuverability, as the main advantage of a hand-held circular saw, can turn into a disadvantage if you need to process a large volume of workpieces. This is where a homemade table comes to the rescue.

  • The design of the table required for a manual circular saw is quite simple, which allows you to do it yourself. A homemade platform requires a little skill and time to make;
  • Drawings and diagrams are not mandatory components for successfully assembling a table with your own hands;
  • The optimal material for making a table for a Bosch manual circular saw is metal;
  • When choosing a metal table for a circular table, do not forget about the massive structure and the need to be able to work with welding machine with your own hands;
  • Often the table is made by hand using wood. They are easier to assemble, which allows a beginner to make them;
  • A Bosch circular saw or its analogues is installed under the table top;
  • The disk should protrude above the tabletop. For this purpose, a special slot is provided on the surface of the table;
  • The lumber is moved along the table surface and cut with a circular saw cutting tool;
  • To increase the processing accuracy, the table can be additionally equipped with a longitudinal and angular stop;
  • The tabletop will take away part of the working disk, so the sawing depth of a manual circular saw will become less exactly by the thickness of the working table. This indicates the need to choose a hand-held power tool that allows you to install large-diameter saw blades;
  • It is recommended to make the desktop with an emphasis on strength and thinness. Metal or durable wood species are suitable for these purposes.

In many cases, it is better to start making a table with your own hands before purchasing the circular saw itself. This will allow you to optimally select equipment characteristics. For a manual circular saw that you want to machine on your desktop, the optimal power would be at least 1.2 kW. This will allow you to cut large quantities of materials efficiently and without overload.

Tools and materials

If you are unlikely to need drawings, it will not be superfluous to reinforce the knowledge acquired in this material with video lessons on assembling tables for circular tables.

To make a tabletop that turns a hand-held circular into a tabletop, you will need certain materials and tools. This list includes:

  • Sheet of laminated plywood. Approximate thickness dimensions - 15-20 mm;
  • Wooden beam. Its dimensions are 50 by 50 mm;
  • High quality board;
  • Switch;
  • Socket;
  • Electrical cable;
  • Glue;
  • Paints and varnishes;
  • Self-tapping fasteners;
  • Electric jigsaw;
  • Screwdriver or electric screwdriver;
  • Ruler;
  • Household drill.

Determine the sizes at your discretion. But if the tabletop circular saw is too compact in size, you will not be able to cut long workpieces with the required comfort.

When choosing sizes, focus on the parameters of the most frequently processed workpieces. The dimensions of the table must be such that the product fits completely on the tabletop. This will allow you to use a Bosch tool to cut lumber efficiently and smoothly with your own hands.

Assembling the tabletop

When everything is ready, you can start working with your own hands. Let's assume that you have already chosen the Bosch power tool itself, or preferred an analogue from a trusted manufacturer, represented by Bosch.

The approximate dimensions of the tabletop, taking into account the selected materials, are 50 by 50 by 25 centimeters. You can make the size of your table larger or smaller depending on personal preference, the size of your workshop, or the characteristics of the Bosch circular saw you are using.

  1. Taking a laminated sheet of plywood as a basis, cut out a tabletop of the size corresponding to the selected parameters. The plywood may not be laminated, but in this case it will need to be coated with a layer of varnish. Apply markings from below so as not to spoil appearance future table. Using an electric jigsaw, cut off the excess and clean the edges.
  2. Turn the sheet over with the bottom side up and mark it for mounting the hand-held circular saw. To do this, remove the saw blade from your circular saw and place the sole of the device against the surface of the sheet. Make marks on the sheet itself and the sole for future fastenings.
  3. Using a drill, drill the holes required for bolted connections. Screw the bolts from above through the table, and from below the structure will be held on by nuts. Here it is recommended to countersink the holes on the working side of the sheet and grind the bolt heads. They won't perform that way.
  4. If you are going to cut material on a machine with a Bosch circular saw at different angles, the hole for the saw wheel should be made in a certain shape - an inverted trapezoid. If you plan only for smooth cutting, it is enough to cut a standard type of groove.
  5. Do not rush to immediately cut the hole according to the markings. Take the circular saw again, attach it to the sheet, check the size matches, after which you can continue working.
  6. Use a pencil to mark where the stiffeners will be installed. To make them, use a wooden board. The ribs are located below, retreating from the edge of the tabletop about 8-10 centimeters.
  7. It is recommended to mount the tabletop legs to the stiffeners. To fix the ribs, use self-tapping screws, screwing them with a screwdriver in increments of 15-20 mm. It wouldn’t hurt to additionally glue everything with PVA glue. Self-tapping screws must be screwed through the top of the desktop, while recessing the heads of the fastening elements. Using long screws, do not forget to connect the stiffeners together.
  8. Using timber or boards, cut out blanks to create the legs of your structure. The length can be 100-120 centimeters. Here you should focus on your own height, since it will be uncomfortable for a tall master to work on a low table. If the legs diverge slightly towards the bottom, this will give them more stability. Fixation is carried out according to the bolt-nut principle. It is a good idea to use washers between them. By making a screed from timber, the desktop frame will be more durable.
  9. You can adjust the height of the table using nuts that are screwed to the legs from below. M14 bolts are suitable for these purposes.
  10. Now proceed directly to fixing the circular saw. Insert the disk into the made slot and secure it with the appropriate fasteners.
  11. It is recommended to screw the socket on the inside of the table, connect the wiring to it and place the switch in a convenient but safe area. Press the on/off button onto the body of the circular saw and secure it.
  12. Using a square pipe and screws with wing nuts, a longitudinal stop is made. Cut the pipe according to the length of the table for the circular table, drill holes for screws 30 mm from the edge of the table top. Using pieces of plywood, a pair of clamps is made.

As you can see, there is nothing complicated in assembling a table top for a circular table. A little time and the design is ready.

A hand-held circular saw is a powerful mechanism with significant productivity. One of the key advantages of a circular saw is excellent maneuverability. But there are also disadvantages, especially if large sizes of wood need to be cut. To make the process easier, you can simply make a table for the circular saw yourself.

Design requirements

Experienced craftsmen are ready to create a table for a circular table with their own hands without any techniques or drawings. However, certain conditions still need to be taken into account.

The essential requirements include:

Availability different functions depends on the working conditions and the wishes of the specialist. These include the ability to carry out high-quality longitudinal and transverse cuts.

Standard products, of which shopping centers hundreds, made of stainless steel. This is wonderful material , but further we consider the production of a table for a saw from wood.

Table design for a manual circular saw is so elementary that most specialists produce it without preparatory drawings and techniques. This is a dense workbench that is created from wood and plywood.

The most durable table bases are made from alloy. They are the heaviest and require the presence of welding skills. Therefore, stands are often made from leftover lumber. A circular saw is attached under the tabletop, and the drive protrudes above it through a specially made slot. The lumber is advanced along the table top and sawn with a disk. For convenience and correct operation, the table is equipped with additional devices: an angular and longitudinal stop.

The tabletop “absorbs” part of the working plane of the disk; the depth of cut will decrease by the thickness of the tabletop. For this reason, it is preferable to choose a circular with the largest disc diameter, and the table cover is thin but rigid.

If you have not purchased an electric saw yet, choose modifications with high power (from 1200 W). They can handle cutting large-sized wood. Holes will be drilled to secure the base. The solid base may burst. For this reason, it is advisable to select a mechanism of a different type.

Material selection

To make a circular table with your own hands, you need to remember carpentry skills, have a lot of patience and a small number of materials and devices.

Materials:

Devices:

  • jigsaw;
  • screwdriver;
  • drill;
  • ruler.

The volume of the countertop will depend on the workshop area. At the same time, it will be uncomfortable to saw large pieces on a small table. If the part is completely fits on the working plane, the cut is made smoother and more accurately. The height of the legs is chosen depending on the height of the master.

Working with a circular saw is very dangerous, for this reason you need to worry about protecting your fingers. Cut a pusher from a piece of wood or furniture board.

Additions to the completed design

Some craftsmen, when assembling a table for a hand-held circular saw according to unique drawings, completely remove the factory safety cover and replace the factory platform with a homemade one. If cutting at an angle is not planned, you can remove all devices for adjusting the tilt of the disk. The electric saw is fixed directly to the new base, which makes it possible to gain a couple of millimeters of cutting depth.

Without inner casing it is easier to remove the disc; the electric saw will not become clogged with shavings when working with wet boards. Dismantling will require extra time, but the service life of the motor is preserved and overload is prevented.

Mounting a circular saw

The matter remains small. The circular electric saw is located inside the prepared hole. The sole is secured with bolts, and the gear drive must fit freely into the socket.

The table for the circular saw is almost ready. Now it needs to be treated with a moisture-protecting material, then coated with varnish in several layers (to minimize slipping).

The resulting system can be supplemented with anything at the user’s discretion (safety cover, device for adjusting the tilt of the disk, carriage, etc.).

A few words about electronics

A circular saw is electrical special equipment that operates from a 220 V power source. If the user has sufficient knowledge and skill in the field of electronics, he is able to bypass the start and pause keys of the saw, and then move them to a convenient place (usually the outside 1st of the stiffeners).

If the model seems complicated, you need to tighten the start button with a wire, and turn on the special equipment using a power cord. However, this method is bad because it eliminates the possibility of quickly turning off the device in the event of an emergency.

Safety requirements

  1. One of the most common causes of injuries when using a circular saw is considered to be a cluttered workplace. In addition, it is important to monitor the stability and strength of absolutely all components of the system, and if there is imbalance, take measures to eliminate difficulties.
  2. Before connecting the saw, you must make sure that it is well secured. If necessary, tighten the screws/bolts.
  3. It is strictly forbidden to hold the material close to the cutting site! This is dangerous as knots and chips bounce into the eyes or onto open parts of the body. Be sure to wear glasses before work and clothes with sleeves.

Making your own saw table is not as difficult a task as it might seem. If you have it on hand good material, its characteristics are chosen correctly, and the power of the device ranges from 500 to 1000 W, the above instructions will be the basis of the work.

You should not lose sight of the fact that at any stage of table production you should control the accuracy of your own operations. Otherwise, if deviations in size or deformation of the legs appear when the ribs are tightened, it will be very difficult to restore stability. However, the production of a circular table with my own hands- an absolutely realistic task for several hours.

Additional Important Information

Carpentry work requires special attention. If you want to make a high-quality and highly reliable table for a circular saw with your own hands, then be well prepared for the work.

Do the following:

Using this article as inspiration, you can make a durable table saw stand for your circular saw.

An excellent tool for sawing various lumber at home is a hand-held circular saw. This power tool can cut lumber of various sections at any angle. This tool perfectly cuts sheets of plywood, hardboard or chipboard.

However, the technical capabilities of such a tool can be significantly expanded, which is often necessary when performing repair work, if you make a stationary machine from a circular saw with your own hands.

It is not difficult to carry out such a transformation, and anyone who needs it can make a machine from a circular saw. To do this, you simply need to fix it on the prepared surface in a certain position. In the simplest version, durable construction trestles can be used as an installation site. For long-term use of a circular saw machine, it is better to make a durable, welded metal frame.

Wooden machine from a circular saw

To make such a wooden base, you will need:

  • sheet of plywood 8-10 mm thick;
  • wooden blocks measuring 40x50 mm;
  • universal glue;
  • self-tapping screws and bolts with M8 nuts.

A sheet measuring approximately 100x60 cm is cut out of plywood (maybe another). Along the edges of the plywood sheet (along its perimeter), bars are attached using glue and self-tapping screws. Then the tool body is applied to the inside of the sheet, and the places where it is attached to it are marked, as well as the groove for the cutting disk. After that, a groove for the passage of the disk is cut out with a jigsaw (or a router), and holes are drilled for attaching the body. The legs are attached to the side bars using bolts. The height of the circular saw machine is selected from 80 to 90 cm. The body is attached to a previously prepared place on its inner side. The bolts for its fastening must be made flush (not protrude on the surface). The lid must be varnished or painted.

To ensure that the material is cut strictly to size, a guide block is installed parallel to the cutting disc. The block can be attached to the table surface with clamps. The wooden circular saw machine is ready for use.

Making a metal frame: instructions

A circular saw machine made of metal is much stiffer and stronger than wood and has a longer service life. To make such a bed, you will need the following material and tools:

  • a sheet of metal (preferably steel) measuring approximately 1000x500 mm and a thickness of 3 to 5 mm;
  • metal corner approximately 45x45 mm;
  • M8 bolts and nuts;
  • welding machine;
  • electric drill;
  • Bulgarian;
  • clamps.

First of all, prepare a table for the machine from a circular saw. To do this, a metal profile is welded around the perimeter of the metal sheet. In order for it to fit tightly to the sheet, it must be pressed to the surface with clamps. Then, on the back side of the sheet, the attachment points for the housing and the groove for the saw blade are marked. Using an electric drill, holes with a diameter of 8 mm are drilled to mount the housing.

On the front side of the table, the holes are countersunk to install fasteners in a countersunk position.

Using a grinder and a drill, a groove for the disk is cut in the table. To cut the groove carefully, you need to drill holes with a diameter of approximately 10 mm along the edges of the intended groove and cut a groove between these holes with a grinder. The tool body is installed and secured to the prepared place.

Four pieces approximately 800 to 900 mm long are cut from the corner for the table legs. Then the legs are welded to the corners of the table. To give greater rigidity, a corner is welded between the legs at a distance of approximately 100 mm from the floor surface.

To ensure high-quality cutting of the material, it is necessary to install a guide bar parallel to the disk. It is best to make it from a corner. To do this, an even corner is cut along the length of the table, then two guides are welded to it, which should fix the movement of the bar parallel to the cutting disk. You can fasten the bar to the table with clamps or using a welded plate with bolts.

After completing the welding work, the welding seams are cleaned, the surfaces are degreased and covered with anti-corrosion paint. The circular saw machine is ready for use.

Making a stationary circular

If you don’t have a circular saw, and you need a more powerful machine for the job, you can make a small stationary machine. Such a machine, manufactured at a factory, is quite expensive, but a machine made by yourself will be several times cheaper. In order to make such a unit, we need the following material and tools:

  • steel sheet with a thickness of 3 to 5 mm, approximately 1200x700 mm in size;
  • metal corner 50x50 mm;
  • asynchronous motor 220 V, 2.2 kW, 2850 rpm. (or another, at the request of the performer);
  • pulley for engine;
  • shaft with bearings and pulley;
  • V-belt;
  • saw blade:
  • M10 bolts;
  • welding machine;
  • Bulgarian;
  • electric drill;
  • clamps.

First of all, you need to purchase a shaft with bearings and a mount for the cutting disc. You can buy it in the store building materials or order and make it in workshops (they often have finished goods and cheaper than in the store).

A frame is welded from a corner to fit the size of the prepared sheet. Then it is temporarily installed on it. After that, the installation locations of the shaft and electric motor are marked. Then two corners are welded into the frame with their flat surfaces facing up to secure the shaft and motor. The prepared frame is attached to the sheet with clamps and welded. A groove for the disk is cut into the sheet. In prepared areas, holes with a diameter of 10 mm are drilled to mount the shaft and motor. In the places where the motor is mounted, grooves are cut in the corners according to the size of the holes (for tensioning the V-belt).

Four corners are cut for the machine legs. The prepared legs are welded in the corners of the table frame. The structure is cleaned of rust, dirt and painted with metal paint. On reverse side The shaft and motor are bolted to the table, and the V-belt is installed. The belt is tensioned by moving the motor along the grooves, and then the mounting bolts are tightened tightly. The engine starting device is attached to the frame at the end. To ensure high-quality cutting, a guide bar is installed parallel to the disk, which can be attached to the table surface with clamps or bolts into pre-prepared holes. The unit is ready for use.

By making a machine from a circular saw, you can greatly facilitate the work of sawing lumber.

By building such a unit correctly with your own hands, you can save significant money.
