How to make a manual circular saw stationary. Homemade circular saw

Reading time ≈ 4 minutes

A circular saw is used to cut wood and plastic. Its cutting base is a flat metal disk with a serrated outer edge. Choosing such a tool, everyone decides for himself what kind he needs: desktop, manual, stationary. Many prefer the manual option. However, in some situations it is necessary to fix the saw. In this case, you can make a table for a circular saw with your own hands, having the opportunity, if necessary, to fix the tool.

Preparation of tools and materials

Having decided to make a table for a manual circular saw on your own, you need to take care of the availability of all the materials necessary for work:

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

For such a table, any hand-held circular saw will do. At the same time, it must be remembered that when attached to the table, the depth of cut decreases by 10-20 mm. So saws with small discs are not suitable for such a table.

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

1. Manufacturing of the case. Sheet material for the body is cut to size: 400 mm by 800 mm. Parts are fastened with screws and bars. It is better to assemble by pre-drilling the outer parts of the box. The result is a rectangular box without a bottom and a lid. The upper part of the bars is subsequently used to secure the plywood sheet.

2. Preparing and fixing the plywood top. Hole cut. First, a piece of 800 mm by 80 mm is cut out of a sheet of plywood. Next, measure the support shoe of the saw that will be mounted on the table top. On the reverse side of the plywood, markup is performed. You will need 2 center axles. Without them, you cannot perform accurate markup. Then marks are applied to the plywood corresponding to the dimensions of the support shoe. Then they make such 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 dimensions obtained, marks are placed and a rectangular hole is cut out with a jigsaw.

3. Fastening the saw to the plywood tabletop. First, 4 holes are made in the shoe. Diameter - 10 mm. Next, install the tool so that the working part goes into the sawn hole. When the saw is leveled, mark the location of the holes. Marks are made in the central part. In order for the tool to stand securely, ploughshare bolts with a countersunk conical head (M8) will be needed for fastening. To install them, you will have to take care of the high-quality deepening of the cap, it can protrude by a maximum of 1 mm in an open form.

Plywood is drilled from the outside, the diameter of the holes obtained should be 8 mm, and then a countersink should be made under the cap. When the holes are ready, the saw itself is installed on the saw table for the circular saw, the bolts are tightened from the inside using nuts with plastic growers 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 tabletop. Then a hole is drilled in the central part of the bars. The parts are connected using a 18 mm M8 steel fitting. On the side part, a regular "Start - start" button is installed. An electrical network is laid inside the case, and the button on the tool itself is clamped.

5. Making a thrust beam. A simple table for a circular saw will become much more convenient if you equip it with a thrust beam. The drawings contain all the required dimensions. The beam can be made of plywood, and secured with full extension furniture rails. The resulting beam should slide over the surface at an angle of 90° to the cutting plane with little clearance.

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

If you want to learn how to make a table for a circular saw with your own hands, then read the article.

It describes the materials that will be required in the course of work, and the main stages of the process aimed at creating a simple but functional design.

Materials and tools

A circular saw is a “serious” tool, using which you need to follow safety precautions.

A homemade table that can be used as a tool stand will allow you to carry out any manual work with greater accuracy and with less injury risk.

Before you make a table, you need to devote time to carefully planning its design.

It is best to create a detailed drawing containing pre-calculated dimensions of the future "stand".

The tabletop, on which it will later be possible to install the saw, should be made of either metal or hardwood. It is better to refuse the use of resinous wood.

The dimensions of the worktop should be chosen in such a way that they correspond to the planned sawing flow.

It is better to use wooden legs as a base. Plastic, even strong and high-quality, should not be used, as it is not the most reliable material for making a saw table.

In order for the made table to “function” in full force, it should be equipped with metal guides capable of moving the material under the saw, or rather, under its working blade.

The optimal size of the bed, suitable for most typical sawing work, is one hundred and twenty by one hundred and twenty centimeters.

If you want to make your table wide and long, then take care of additional stops that will support its construction.

In particular, to give the product stability, it can be equipped with not four, but six legs.

The assembly of the table for manual is carried out using additional materials, including:

• wooden bars designed to form the frame of the structure;
• fastening dowels;
• wood glue;
• metal "corners" for attaching the legs;
• nails and screws.

Tools that may be needed during the work:

• tape measure and hard construction ruler;
• electric jigsaw or hacksaw;
• apparatus having an installed milling tip;
• sandpaper (or grinder);
• hammer and planer;
• screwdriver (or screwdriver).

Stages of making a table for a circular saw

The creation of a table for a saw should begin with the assembly of its frame. To perform this procedure, you can use bars or edged boards, the size of which is fifty by one hundred and fifty millimeters.

The boards need to be hammered together into a single square or rectangular structure, which will serve as both a frame screed and the basis for attaching the legs.

The frame made should be connected to the legs, using special metal corners, dowels and self-tapping screws during the process.

These devices must also be used to connect the assembled frame to the countertop.

As an alternative, the frame elements can be connected not to each other, but to the legs of the future table. Some carpenters believe that this design is more durable.

The installation of the saw must be carried out on an inverted bed. Thanks to this, its body and motor will be on the bottom, and the disk, otherwise called the working blade, on top.

A hole that allows you to deepen the frame of the saw into the table should be cut in advance with a hacksaw or electric jigsaw.

It is important to remember the correct selection of the size of the hole, which will reliably “hold” the saw, guaranteeing the overall solidity of the structure.

Most circular saws have special metal parts that give them stability.

To fix the device on the countertop, you should make four bars with sawn grooves and drill holes in them for long bolts.

After installing the saw, you should put prepared bars on its carriage, thereby pressing the device to the bottom of the tabletop.

When attaching the support bars and saw to the tabletop, it is important not to damage the outer part of the bed, so as not to create obstacles on its surface for the normal movement of the boards intended for sawing.

When the saw is securely attached to the table, you need to turn the bed over and screw it to the tie rod.

At this stage of the work, you should make sure that all work has been carried out correctly and the device functions without problems.

Only then can the material guides be attached to the table.

Additional Information

Carpentry needs attention. If you want to make a high-quality and reliable table designed for installing a circular saw, then thoroughly prepare for the process and purchase all the necessary materials and tools.

After assembling the frame, be sure to install it on a flat surface and check that the countertop of the structure does not outweigh it in any direction.

It is better to set the table for the place where it will stand in the future, in order to eliminate possible problems associated with uneven floors.

If, due to an uneven floor, the table vibrates during the operation of the saw, then the length of the legs should be adjusted using dense felt or rubber.

The tabletop of the product can be both monolithic and folding. To create a folding table for a saw, you will have to spend more time and material, and pay special attention to improving the reliability of the bed, which is disassembled.

The dimensions of the consumable used to create the table are determined empirically. Ideally, the height of the structure should correlate well with the height of the saw owner.

The hole that will be made in the table top must match the dimensions of the particular saw that is available.

In order to extend the service life of all materials used, assembled into a single structure, they should be treated with special chemical solutions that can improve the performance of wood or metal (for example, protect their surface from corrosion, decay, mold, etc.).

It is better to process wood or metal outdoors, and not indoors, so as not to be poisoned by active fumes.

Inspired by this article, you can make not only a reliable stand for a circular saw, but also a table where you can drink and eat, gathering with the whole family.

The technology that underlies the creation of a dining table is in many ways similar to the scheme, using which you can put together a wooden table for a circular saw.

In the course of work aimed at creating a table for a circular saw, it is important to remember safety precautions.

A circular saw is used to cut wood.

Using a hand saw is not always comfortable, using a table allows you to make the sawing process more even and accurate.

The cutting base has a plane resembling a disk, equipped with an outer edge with teeth. There are models not only of the manual type, but also with the possibility of fixing on the table.

It is difficult to work with large volumes of wood with a conventional circular saw, so it is better to install it on a table

There are several ways to acquire the latter for the convenience of performing manipulations. A table for a circular saw can be built independently, strictly adhering to a certain scheme.

Table device for a circular saw

The table is made taking into account the fact that the hand tool will be installed and fixed on the table, turning into stationary equipment.

Do-it-yourself construction of the element allows you to make the saw as suitable as possible for individual conditions. Difficulties in the process will not arise if you carefully study the issue. You can adjust the product to the desired size, distribute everything so that it is convenient for you.

Making a table for a circular saw is quite within the power of every craftsman

The self-made model will be one of a kind, which makes it unique.

Deciding on design and construction

The simplest option for a circular table is a construction made of fairly thick plywood and boards.

The base can be made of wood or metal. For countertops, leafy tree species are chosen. It should make a special hole for the disk. The key property of the created table should be convenience.

Circular machine bed

You should take care of its stability. No loosening is allowed, otherwise it will negatively affect safety. The table top should be as flat as possible. This will reduce the risk of injury at work.

A table for a circular saw requires the presence of guides

The structure can be supplemented with a special riving knife. He can take off. It is equipped with a special disc protection that allows you to get rid of chips flying into the worker.

Circular table guide carriage

Some remove the factory casing and change the factory platform to a homemade one. If you are not going to cut at an angle, you can remove the parts that adjust the inclination of the blade.

Scheme for making a table for a circular saw

Before starting work, it is recommended to go through the preparatory stage. Be sure to make a drawing. This will make the design process easier. First calculate the dimensions of the table, then transfer the data to paper. The hole made in the structure must exactly match the dimensions of the saw. It all depends on the brand of equipment. Therefore, it is impossible to make a universal hole. The base must be stable and well withstand mechanical loads.

Do-it-yourself circular table drawing

It is unacceptable to hang the structure to one side. The dimensions of the worktop must be suitable for the sawing flow. The final option is determined based on individual desires. Some work comfortably with a folding table or a product with small dimensions.

Drawing of a universal desktop machine

The drawings should take into account an important point. If you plan to leave tools or materials on the table during work, then the dimensions of the countertop must be increased to a square meter in area. A suitable size would be 120 by 120 cm. You should draw carefully and slowly in order to do everything correctly.

Necessary materials

Homemade table can be made of wood

For such a table, wood, plywood or chipboard can be used. Also suitable for MDF and chipboard. Some prefer to choose steel or aluminum.

Steel Plate Circular Machine Table

It is not recommended to use plastic, it is completely unsuitable for a table of this purpose. If wood is selected, then after assembly is completed, the product should be treated with a special antiseptic composition. This will provide reliable protection against moisture and help to avoid rotting.

To make a saw table yourself, you need to prepare the materials.

1. Selected raw materials for the base. The thickness should be 21 mm.
2. The beam needed for the frame. Suitable edged board 3 meters long with dimensions of 50 by 150 mm. All you need is 5 pieces.
3. Dowels made of wood with dimensions of 10 cm. At least 12 pieces.
4. Joiner's glue.
5. Metal fasteners in the amount of 4 pieces.
6. Metal corners. Enough 10 pcs.
7. Self-tapping screws.

These elements must be prepared in advance and placed near the workplace.

Required Tools

In addition to materials, tools should be prepared.

Among them:

1. pencil and marker;
2. measuring instruments, including a meter and tape measure;
3. jigsaw;
4. manual frezer;
5. grinding machine;
6. sandpaper (should have medium or fine grit);

First make sure that the saw is securely fastened, only then turn it on. Do not hold the cut material with your hands. This will help keep the wood from getting in your face when the knots start to bounce. In addition, it is recommended to use special protective goggles when working.

Be sure to use protective goggles for your safety.

These simple tips will help you avoid injury in the workplace.

Video: Circular table made from improvised materials

The main component of a carpentry home workshop is a circular saw. It is intended for primary processing of materials by manual or automated method. Due to the high cost of factory equipment, craftsmen most often come to the conclusion that it is best to make this machine with their own hands.

Requirements for household circular machines

Structurally, it should not differ from factory models. They consist of a support table, in the center of which there is a slot for a saw blade. In addition, the design contains measuring components, elements for fixing the workpiece and for ensuring the safety of work.

Before manufacturing, it is necessary to familiarize yourself with the basic requirements for its components. It is important that they fit each other not only structurally, but also in terms of technical parameters. To do this, you can take a diagram of a typical design of a factory woodworking machine.

Complete set of woodworking saw equipment:

• table. Must have sufficient stability, the surface of the countertop is perfectly flat;
• power point. The main parameters of the electric motor for rotating the disk are power and number of revolutions;
• additional components. These include stops for fixing a wooden workpiece, rulers for measuring.

The advantage of home-made models is the ability to choose its dimensions, performance and other technical parameters. In the process of drawing up a manufacturing scheme, you can choose the optimal height of the table, the dimensions of the tabletop, and the characteristics of the electric motor. This does not have a hand tool for woodworking.

Requirements for woodworking discs directly depend on the parameters of the workpiece, the type of wood and the required productivity speed. This is calculated on an individual basis.

Materials for the manufacture of a circular machine

After drawing up the optimal drawing for the manufacture of stationary equipment with your own hands, you need to select consumables. To do this, you can purchase rolled metal or use existing components.

The main problem is the choice of the power unit. Some recommend installing a factory-made hand saw. However, often they do not have the necessary power to process large volumes of wood. In addition, the limitation on the diameter of the disk will reduce the functionality of the equipment. Therefore, it is best to choose drawings in which there are two separate blocks - an electric motor and a shaft for mounting the disk.

The connection of the load-bearing elements of the desktop is carried out by do-it-yourself welding. Mechanical components will not provide a proper indicator of reliability, as backlash will form due to constant vibration.

• table. For legs, you can use steel corners 30 * 30 or 40 * 40 mm;
• countertop. It is made of dense chipboard, although experts consider the use of a steel sheet to be the best option. In this case, a lattice structure is made in the upper part of the table;
• electric motor. You can use any household model of a 220 V asynchronous power plant, the power of which does not exceed 1.5 kW, and the maximum number of revolutions is 2400 rpm .;
• a system of pulleys for transmitting torque on a shaft with a disk. Pulleys are best taken from the factory. A tensioning system must be provided.

To fix the workpiece along the length, it is necessary to provide a support bar. It should shift relative to the plane of the disk, thereby adjusting the width of the board being processed with its own hands.

Before welding, all steel blanks must be cleaned of rust. Painting is carried out only after the final manufacture of the saw machine with your own hands.

Assembling a homemade circular machine

After preparing the components, you can begin to assemble the structure on wood. Drawings are drawn up in advance, on which all the parameters of the elements are indicated: dimensions, welding places, mandatory processing zones.

First, the frame of the saw machine is assembled with your own hands. It is necessary to provide places for mounting the shaft with the disk and the electric motor. Pulleys should be located on the outside. This is necessary for the periodic tightening of the transmission belts and the prompt implementation of repairs.

According to the diagram, a slot is made in the center of the tabletop through which the disk will pass. The edges of the material must be processed, but the countertop must be even. The plane of the disc must be strictly perpendicular to the surface of the table. Recommended slot dimensions: width - up to 5 cm; length - up to 400 mm.

The motor control unit is located in front of the cutting area. This will help prevent chips from getting into electrical components.

To get acquainted with an example of making a circular saw with your own hands, it is recommended to watch the video material:

Content:

Circular type machines belong to the class of specialized processing mechanisms, without which no well-equipped home workshop can do.

This sample of woodworking equipment is especially relevant in the conditions of a country house and a summer cottage.

When evaluating the possibilities of purchasing ready-made equipment, you will encounter a number of problems related to the inconvenience of handling cheap stand-alone circular saws and the too high cost of professional processing equipment.

The only correct approach to solving this problem is to make a circular machine with your own hands, using materials and equipment that are commercially available.

Note! In order to save money in small-sized models of machine tools, an autonomous circular saw is most often used as a cutting tool, which is rigidly mounted on the bed.

With the help of a home-made machine, you can saw boards, plan a slab, and also make bars of the section you need.

If desired, it will be possible to significantly expand the functionality of your product by providing it with the possibility of processing wood using an electric planer.

Design requirements

Before starting work, it will be necessary to prepare a small sketch, which should indicate not only the location of all the structural elements of the future machine, but also their main dimensions. When drawing such a sketch, it should be taken into account that your circular machine may consist of the following functional units:

• bed, which serves as the basis of the entire product;
• countertops with an industrial model of a hand-held circular saw installed on it;
• remote control panel for turning on and off the actuator (circular saw).

Small Tabletop Circular Machine

The specified composition of the machine is typical for small-sized products on a wooden frame. For capital equipment manufactured on the basis of metal profiles (corners), its scheme has a slightly different look. The composition of such a product should include the following elements:

• a base made of steel frames and brackets on which a shaft with a drive pulley is mounted in bearing pairs;
• a tabletop with slots for the processing blade, mounted on top of a metal frame and rigidly fixed to it;
• a set of special drive electrical equipment located in the lower part of the frame and providing the required functionality of the device (it includes an electric motor, a starting device and a transformer-converter).

The main requirement for any type of bed is to ensure maximum reliability and stability of the structure. As options for the execution of the machine base, we will consider both frames made of metal profiles (corners) and load-bearing structures made of wood.

When familiarizing yourself with the requirements for the electrical equipment of a home-made machine, first of all, you should decide on the power of the drive of the cutting tool (or autonomous saw), which for domestic conditions should not exceed 850 watts.

Stationary circular machine

In addition, before preparing a sketch of a future product, such technical characteristics of the equipment used as:

• Depth of cut, which sets the allowable thickness of the wood pieces to be processed on your machine. This indicator for industrial samples of woodworking equipment ranges from 5 to 8 cm, which is quite enough for cutting standard boards and thick plywood.

Additional information: In the event that you need to process wood blanks of greater thickness, it is necessary to provide a special lifting mechanism in the bed that allows you to change the position of the disk in height.

• Before manufacturing a capital machine with a separate drive, the operating frequency of the rotor of the electric motor should be taken into account. The choice of this parameter is determined by the lumber processing modes that you most often have to deal with. For simple cutting of wood, this figure can be relatively low, but for a perfectly even (“clean”) cut, you need a higher speed.

Important! Optimal for homemade cutting machines is considered to be a speed that does not exceed the value 4500 rpm. At low engine speeds, the frame can be made on the basis of a reinforced wooden frame, massive enough to prevent mechanism vibrations.

• When drawing up a sketch, ergonomic requirements should also be taken into account, assuming the convenience of controlling the operation of the equipment, as well as the safety of handling it. They relate to the order of the buttons on the operating panel, the restriction of access to the cutting blade, as well as the electrical safety of the drive or individual controls.

After all possible requirements for the future machine are taken into account, you can proceed to its direct assembly.

Frame based on metal profiles (corners)

The upper part of the metal frame is most conveniently made in the form of a rectangular frame 600 by 400 mm, welded from 25 mm corners. Pipe blanks 220 mm long are welded to the four corners of this design (recommended pipe diameter is 17-20 mm).

The bed must ensure the rigidity of the machine

On the frame with the help of bolts, two longitudinal corners are used to fasten the shaft in the bearing cage.

The distance between the corners is determined based on the length of the shaft, and the bearings used for installation are fixed on them with special clamps.

The lower part of the frame of the bed, in order to give it greater stability, is made (welded) from 40 mm metal corners.

Closed type bearing is used to fasten the working shaft

Two jumpers made of the same material are welded across the frame, used to fix the electric motor. There is also a metal platform intended for mounting the launch equipment.

Bearings are attached to the frame with special clamps.

At the corners of the resulting structure, pipe blanks are welded with a length corresponding to the size of the pipes on the upper frame, but with a slightly larger diameter (23-25mm).

Closer to their edge, special clamps (lambs) are used to clamp the lifting pipes of the upper frame, which move when the drive belt is tensioned.

The procedure for assembling the mechanical part of such a machine includes the following operations:

• first, bearings No. 202 are taken and driven onto the working shaft with force;
• after that, a pulley is fixed on the same shaft with an interference fit, previously machined on a lathe and having an inner diameter of the stream of 50 mm;
• then, at the end of the shaft, a thread is cut for the bolt used to clamp the cutting tool (for more reliable fixation, paronite and metal washers can be placed under the bolt);
• upon completion of this part of the work, we proceed to the installation of a drive manufactured on the basis of a three-phase asynchronous motor with a power of 1.5 kW (1500 rpm). A pulley is mounted on the shaft of such an engine, having an internal size of the stream of approximately 80 mm;
• at the next stage of assembling the frame, two finished halves of the frame are connected together (in this case, pipes of smaller diameter are inserted into larger ones);
• at the end of the work, a belt is pulled on the shaft, and then the structure is fixed in this position by means of special “lamb” clamps.

Machine on a wooden frame

The easiest and most affordable way to make a machine bed involves the use of ordinary boards or thick plywood for this purpose. In this version of the design, the actuating unit is placed directly under the table (table top), in which a slot of the appropriate dimensions is made for the cutting blade.

Wooden frame is reliable and easy to manufacture

As an example, we will consider the option of manufacturing a bed with a height of approximately 110 - 120 cm, designed to fix a hand-held circular saw on it. The length of the countertop of this design can be changed within small limits at your discretion.

Note! The height of the structure, if desired, can be adjusted, taking into account the height of the person working on the machine. And if it is necessary to process very long boards on it, the dimensions of the countertop can be increased to the required size. In this case, you will have to worry about mounting additional support legs.

The most convenient material for making countertops is multilayer plywood with a thickness of at least 50 mm. However, other materials can be chosen for these purposes (plexiglass or fiberglass boards, for example). As for such a common material as chipboard, its use in this case is undesirable, as it does not provide sufficient surface strength.

To make a machine on a wooden base, you will need the following materials:

• preparation of sheet iron;
• standard sheet of thick plywood;
• a pair of bars with a section of 50x50 mm;
• thick boards with a standard size of 50 x 100 mm;
• steel corner, necessary to increase the rigidity of the fastening of the guides;
• a circular saw;
• two clamps.

In addition, you will have to stock up on the following set of tools, without which the assembly of the machine is simply impossible:

• classic screwdriver and electric drill;
• a simple hacksaw for wood or a jigsaw;
• measuring instruments (square, tape measure, ruler);
• portable cutter for wood processing.

In the absence of such a cutter, it will be possible to use the help of friends or neighbors who have a milling machine in their household.

Additional Information: Some home crafters prefer to make countertops from end-of-life kitchen tables. However, this design will not be durable, since the source material has been used for a long time in a humid room. That is why it would be wiser to make all structural elements from new blanks, which at the same time will allow you to take into account your personal tastes and preferences.

Countertop manufacturing

Work on the manufacture of this part of the equipment is carried out in the following sequence:
We start by marking a piece of plywood, carried out in such a way that its edges are flush with the edges of the prepared iron sheet. After marking, using a hacksaw or electric jigsaw, you can cut the plywood blank to the required size. If desired, it will be possible to process its edges with a cutter, although this is not at all necessary (the main requirement for this element is its reliability, not attractiveness).

Upon completion of these operations, the surface of the countertop is carefully processed (rubbed) with an emery cloth of medium grit.

Then, on its lower part, the position of the slot for the saw blade is preliminarily marked. To do this, it is necessary to determine the dimensions of the sole prepared for the installation of a circular saw. For the convenience of carrying out measurements, the disk is simply removed from the saw, after which it will be possible to easily determine the dimensions of the seat.

For the convenience of marking the tabletop, the saw blade is removed

Upon completion of its preparation, you should take a circular saw and try it on at the installation site. If necessary, the position of its attachment points is corrected (at the same time, the contours of the slot for the saw blade are specified).

The finished plywood table top is covered with a steel sheet, fastened to it with self-tapping screws. Subsequently, special markings can be applied to the working surface, allowing you to adjust the position of the wood blank during its processing.

Frame assembly

Both transverse and longitudinal bars of the frame, used as stiffeners, are also mounted on the lower plane of the tabletop. In total, four such strips are required:

Two transverse jumpers that do not reach the edge of the tabletop by 7-9 cm on each side.
Two longitudinal bars, the size of which corresponds to the same condition (they should not reach the edges of the countertop by about 7-9 cm).

Taking into account these restrictions, it is necessary to outline the points of fixation of the longitudinal bars and crossbars, in which the latter will be attached to the countertop using self-tapping screws of a suitable size.

When marking points, the outermost of them is selected approximately at a distance of 40-50 mm from the edge of the bar (in this case, the step between them should be about 23-25 ​​cm).

Before the final assembly of the frame, through holes for self-tapping screws are drilled in all component parts (bars and countertop). On the front side, the fastening elements are installed in such a way that their caps are completely hidden in the material.

To increase the strength of the future frame base, the bars adjacent to the countertop are pre-coated with wood glue.

After assembly, the structure is temporarily fixed with clamps, which can be removed after the glue has dried.

Support leg attachment

The legs of the table are made from bars of a suitable section (most often, the same 50x50 mm blanks are used for these purposes). The height of the supports is selected for a specific person, i.e. individually.

This should take into account the fact that it is more convenient to work on a circular machine when the tabletop is at hip level. The shape of the legs before their final installation is finalized, taking into account that they taper towards the supporting part (the area of ​​​​interfacing with the frame base must exceed the area of ​​\u200b\u200bsupport on the floor).

To increase the rigidity and stability of the structure, steel corners can be used in it, which are pressed in such a way as to provide an additional “strut” of the base. To fix them, special bolts with washers are used, installed with caps outward.

Wiring diagram

In the capital version of the design of the circular machine, an autonomous drive is used, which includes an asynchronous type electric motor, the windings of which are connected to the electrical network according to the triangle scheme.

Connection diagram of an asynchronous motor of a circular machine

To control the operation and ensure automatic start of the electric motor, the circuit provides for a magnetic starter built on the basis of an electronic switch (triac) and a current transformer.

To build a machine control scheme on a wooden frame (an option involving the use of a manual circular saw), it will be enough to duplicate the buttons for turning the mechanism on and off, bringing them out and fixing them on one of the legs of the table top
