Joiner's table with a circular saw. How to make a reliable circular table with your own hands? Saw frame design

Content:

In a well-equipped carpentry workshop, equipped in a country house or in a private house, a circular disk mechanism is required to process wood blanks.

Very often used as household woodworking equipment homemade machine, made on the basis of a hand-held circular saw or a cutting tool with an independent electric drive.

To accommodate any of these mechanisms, a specially equipped table with a surface that provides the convenience of working with wood blanks is required.

Depending on the type of cutting tool, as well as on the material used for the manufacture of the bed, the table for a circular saw can have the following designs:

firstly, it can be made in the form of a workbench with legs and a manual circular saw(light version);
secondly, it can be equipped cutting disc structure mounted on a metal frame. The drive part of such a machine, consisting of an electric motor and control circuits, is located in the lower part of the bed (capital option).

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

Design choice

Before you make a table for a circular saw with your own hands, first of all, you need to decide on its design. So, a lightweight version based on plywood and beams should contain the following mandatory elements:

tabletop directly;
plywood body;
support legs for good stability
The structure of the capital structure should include the following nodes:

bed based metal profiles or corners;
upper and lower brackets, necessary to accommodate the cutting blade with a shaft and drive equipment, respectively;
the table itself with a slot for the cutting blade, mounted directly on the metal frame.
The most affordable for manufacturing at home is considered wooden table for circular saw(i.e. lightweight design).

A lighter version of a table for a circular saw will look something like this

Preparation of sketch, material and tool

As an example, consider the procedure for manufacturing a wooden workbench with a height of approximately 100 - 120 cm. Before making such a table with your own hands, it is advisable to prepare a small sketch that will display the device of the future design, indicating the dimensions of its main elements.

The exact setting of the table height is made taking into account the growth of the master working on the machine (the location of the working plane at the level of the human hips is considered comfortable).

On the preparatory stage you should also decide on the material for the manufacture of the future structure, which, as a rule, is made of beams and plywood with a thickness of 28 mm.
In order to make such a table with your own hands, you will need the following blanks:

metal sheet of suitable size;
standard sheet of thick plywood;
a metal square pipe from which the guides are made;
a set of clamps in the amount of two pieces.

To assemble the table, you also need a tool kit from the following items:

screwdriver and electric drill;
jigsaw or ordinary hacksaw on wood;
square, tape measure, ruler (for current measurements);
manual frezer

Making a table cover

The procedure for manufacturing this structural element involves the following operations:

Work begins with marking and cutting out a plywood blank, the dimensions of which must correspond to the dimensions of the prepared iron sheet.

After adjusting to size, the surface of the workpiece is carefully polished with an emery cloth.

Then on the bottom surface plywood sheet points of fixation of the actuator are outlined with simultaneous marking of the slot for the cutting disc.

To do this, first try on the sole of the circular saw used at the installation site. In this case, it is most convenient to simply remove the disk from it and determine the exact location of the landing points.

Before installing it at the place of attachment, an additional check is made for the correct marking of the slot for the cutting disc.

The marking of the table top is done directly on the sole of the circular saw

At the final stage, the working surface is closed with a steel sheet with two guides, which is then fixed with ordinary self-tapping screws.

Subsequently, special markings can be made along the guides from the corners, which increases the convenience of processing wood material.

Additional information: In addition to plywood, plexiglass or fiberglass can be used to equip the operating surface of the table.

Assembling the frame with legs

The base or frame of the table is assembled from a set of transverse and longitudinal wooden beams, which are attached from the bottom of its cover, increasing the rigidity of the entire structure as a whole. For this, four bars with a section of 50x50 mm are quite enough, placed with an indent from the edge of the table of about 7-9 cm.
They are fixed on the bottom of the lid with suitable-sized screws in increments of approximately 23-25 cm. On its front side, the fasteners are sunk into the material that completely hides their caps.
The frame can be made stronger by pre-treatment of the joint surface of the bars with a layer of wood glue, which is carried out immediately before they are fastened. After connecting the blanks smeared with glue, the latter are securely fixed with clamps, which are removed immediately after the adhesive has dried. The legs of the structure can be made from bars of the same section as the blanks for the frame (50x50 mm).

The design of the table must be strong and rigid.

The shape of the legs is selected based on the fact that they provide the maximum support area for the frame part of the base and have a shape that tapers towards the flooring. On one of these legs, subsequently, controls are placed to turn the saw on and off, duplicating the buttons located on its body.

You will be able to additionally increase the rigidity and stability of the entire structure with the help of a set of steel angles mounted in the area of its butt joints. To fix them, it is recommended to use standard bolts with washers, which are preferably installed with their heads outward.

Features of the manufacture of a metal frame (bed)

The upper part of the metal base is a welded frame 800x800 mm in size with legs welded at the corners from pipes 220 mm long and with a cross section of approximately 17-20 mm.

On the frame of 25 mm corners, two longitudinal profiles are attached, used to install the shaft on bearings.

To ensure greater structural stability, the lower part of the frame is welded from larger corners (40 mm) and has two jumpers designed for mounting an electric motor with starting equipment circuits. At its corners, pipes are also welded, having the same length as on the upper frame, but somewhat larger in diameter (23-25 mm).

Closer to the edge of such legs, threaded holes are prepared from pipes, in which special holders(they are also called "sheep"). With the help of these winglets, it will be possible to fix the position of the pipes of the upper part of the frame, which is moved in order to regulate the tension of the drive belt.

Functional expansion

In conclusion, let's touch on the topic of expanding the functionality of your working structure. If there is free space on the operating surface, additional woodworking equipment (electric planer or milling cutter, for example) can be mounted. The presence of a planer and a wood router will allow you to expand the functionality of the machine and turn it into a full-fledged woodworking center.

In addition to this, such a router can be equipped with a special mechanism for adjusting the position of its working part, which can be changed within specified limits (the so-called elevator).

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 less risk of injury.

Before you make a table, you need to devote time careful planning his designs.

Best to create 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.

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

To make the table "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, among which:

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 screws.

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 has more strength.

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.

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

It is important to remember about correct selection the size of the hole that will securely “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 high quality reliable table designed for installing a circular saw, then thoroughly prepare for the process, and purchase all necessary materials and tools.

After assembling the frame in without fail set it to flat surface and check that the table top 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 exclude 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.

Dimensions 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 increase performance characteristics wood or metal (for example, to 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 behind the creation 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.

The manual circular electric saw is a powerful mechanism with significant productivity. One of the key advantages of the circular is excellent maneuverability. But there are also disadvantages, especially if you need to cut large sizes of wood. In order to facilitate the process, you can simply make a table for a circular saw yourself.

Design requirements

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

The essential requirements include:

The availability of 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 sawing.

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

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

The most durable table bases are made from alloy. They are the most difficult and require the presence of welder skills. Therefore, often coasters are made from the remnants of lumber. A circular saw is attached under the tabletop, the drive protrudes above it through a specially made slot. The lumber is moved along the table top and sawn into a disk. For convenience and correct operation, the table is equipped additional devices: angular and longitudinal emphasis.

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

If the saw has not yet been purchased, choose modifications with high power(from 1200 W). They can cut wood large sizes. Holes will be drilled to attach the base. The one-piece base may burst. For this reason, it is desirable 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, stock up on great patience and a small number of materials and appliances.

Materials:

Devices:

jigsaw;
screwdriver;
drill;
ruler.

The volume of the countertop will depend on the site of the workshop. Along with this, on small table It will be uncomfortable to cut large pieces. If the item is completely fits on the working plane, the cut is smoother and more accurate. The height of the legs is chosen depending on the height of the master.

Working on a circular saw is very dangerous, for this reason, care must be taken to protect the fingers. From a piece of plank or furniture board cut out the pusher.

Additions to the made 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 sawing at an angle is not planned, all devices for adjusting the inclination of the disc can be removed. The power saw is fixed directly on the new base, which makes it possible to win a couple of millimeters of cutting depth.

Without inner casing it is easier to remove the disc, the saw will not clog with chips when working with wet boards. Dismantling will require extra time, but the motor resource is preserved, congestion is prevented.

Circular saw installation

The matter is small. The circular electric saw is located inside the prepared hole. The sole is reinforced with bolts, and the toothed drive should fit freely into the socket.

The table for the circular saw is almost ready. Now it must be treated with a material that protects against moisture, then varnished in several layers (to minimize slip).

The resulting system can be supplemented with something at the discretion of the user (safety cover, device for adjusting the inclination of the disc, carriage, etc.).

A few words about electronics

A circular saw is an electrical special equipment powered by 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, this is the outside 1st of the stiffeners).

If the model seems complicated, you need to tighten the start key with a wire, and turn on the special equipment with a power cord. However, this method is bad because it excludes the rapid shutdown of the device in the event of an emergency.

Security requirements

One of the most common causes of injury when using a circular saw is the clutter of the workplace. In addition, it is important to monitor the stability, strength of absolutely all components of the system, and in case of imbalance, use measures to eliminate difficulties.
Before connecting the saw, make sure that it is well fixed. If necessary, tighten screws/bolts.
It is strictly forbidden to hold the material close to the cutting point! This is dangerous by bouncing knots, chips into the eyes or onto exposed parts of the body. Be sure to wear glasses before work and clothes with sleeves.

Making a table for a saw on your own is not such a difficult task as it might seem. If you have 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.

It should not be overlooked that at any stage in the production of a table, the accuracy of one's own operations should be controlled. Otherwise, if there are deviations in size or deformation of the legs 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 real task for several hours.

Additional important information

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

Do the following:

Inspired by this article, you can make a sturdy table stand for your circular saw.

The hand circular saw is powerful tool with high performance. One of the main advantages of a circular saw is that maneuverability becomes a disadvantage when large volumes of wood need to be cut. To simplify the process, you can easily assemble a table for a circular saw with your own hands.

Table device

The design of the table for a manual circular saw is so simple that most craftsmen make it without preliminary drawings and diagrams. This is a sturdy workbench that is made from wood and plywood. The most reliable table bases are made of metal. They are the heaviest and require the skills of a welder. Therefore, more often coasters are made from lumber waste. A circular saw is attached under the tabletop, the disk protrudes above it through a specially made slot. Timber is moved along the countertop and sawn with a rotating disc. For convenience and accuracy of work, the table is equipped with accessories: angular and longitudinal emphasis.

The tabletop "eats" a part working surface disc, the depth of cut will decrease by the thickness of the tabletop. Therefore, it is desirable to select a circular saw with a maximum disc diameter, and a thin but rigid tabletop.

If the saw has not yet been purchased, select models with high power (from 1200 W). They can cut through large volumes of wood. Holes will be drilled in the sole for fastening: the molded base may crack. Therefore, it is advisable to choose a tool with a stamped sole.

Selection of materials

To do good stand for a manual circular saw, you should remember carpentry skills, be patient and a small amount of materials:

laminated plywood 15 - 20 mm;
timber 50 x 50;
board;
switch;
external socket;
piece of electrical cable;
PVA glue;
wood varnish (if the plywood is not laminated);
self-tapping screws.

And tools:

jigsaw;
screwdriver;
drill;
ruler.

The size of the countertop will depend on the area of the workshop. However, on a table that is too small, it will be inconvenient to cut long pieces. If the entire part fits on the work surface, the cut is smoother and more accurate. The height of the legs is selected depending on the height of the master.

For a small workshop, a desktop design with approximate dimensions of 50 x 50 x 25 cm is convenient.

Table making process

From a sheet of laminated plywood, we cut out the countertop of the required size. The marking is applied to the lower plane using a metal ruler and a pencil. We cut the plywood with an electric jigsaw, mill the edges if necessary. If the plywood is not laminated, we clean the surface of the table with sandpaper.
We turn over and from the bottom we make markings for fastening manual circular. To do this, remove the disc from the tool and set it with the sole in the desired place. We make marks on the table top and on the sole for fasteners and a groove for the saw blade. We drill holes for the bolts. They will be screwed from above, through the countertop and from below held by nuts. Therefore, from the side of the working surface, we countersink the holes, and grind the bolt heads so that they do not protrude.
If you plan to cut the material at different angles, the slot for the saw blade is made in the form of an inverted trapezoid. For even sawing a normal groove is performed. Before cutting the slot and holes for fasteners, attach a saw, correct the marks, and only then cut.
Mark with a pencil the location of the stiffeners. They are made from a board and installed from below 8 - 9 cm from the edge of the countertop. We will attach the legs of the table to the ribs. The ribs are fixed with self-tapping screws at intervals of 15 - 25 centimeters, additionally glued with PVA. Self-tapping screws are screwed in from above, through the countertop, the heads are completely recessed. The ribs are fastened together with long self-tapping screws.
The legs of the table are made of a bar or board, their length will be from 100 to 113 cm. The legs, slightly diverging downwards, will give greater stability. They are fixed on large bolts, twisted from the outside, fastened with nuts from the inside. Screeds from a bar will additionally strengthen the frame.
To adjust the height of the table, nuts are attached from below, into which M14 bolts are screwed.
Now you can fix the saw from below by passing the disc into the prepared slot.
We attach an electrical outlet to the inside of the table, pass from it electrical wire and set the switch to convenient location(on the outer part of the stiffener). The outlet will be powered by the switch. From it we stretch the wire to the nearest power source in the workshop. Via construction screed we fix the ON-OFF button on the body of the circular saw in a recessed position.

Let's start making auxiliary stops. For the longitudinal stop, you will need a #30 aluminum square tube and two screws with wing nuts.

We saw off a piece of pipe along the length of the countertop, cut holes for the screws 3 cm from the edge.
We cut out two clamps from pieces of plywood. The structure is ready.
For sawing across the table, we make a plywood sled. We align them relative to the edges of the table, press and move along the jagged circle. In the place where the circle passes in the sled, we cut a groove. Small parts can be stacked directly inside the sled and sawed.

Dust removal is organized from under the table, but most of the dust is scattered from above, so it’s a good idea to supplement the device with an upper dust extraction.

Working with a circular saw is very dangerous, so care must be taken to protect your fingers. Cut out a pusher from a piece of board or furniture board.

Additions to the design

This design can be supplemented with a riving knife, which will be removed. Put on a disc protection on it, which cuts off the flow of chips flying directly into the carpenter.

Some masters, assembling a table according to unique drawings, completely remove the factory protective cover, and replace the factory platform with a home-made one. If you do not plan to cut at an angle, you can also remove all devices for adjusting the blade tilt. The saw is fixed directly on the new base, which allows you to gain a few millimeters of cutting depth.

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

The design of the table required for a manual circular is quite simple, which allows you to do it yourself. A homemade platform requires a bit of skill and time to make;
Drawings and diagrams are not mandatory components for the successful assembly of the table with your own hands;
The optimal material in order to make a table for a Bosch manual circular is metal;
Choosing for a circular metal table, do not forget about the massiveness of the structure and the need to be able to work with welding machine with your own hands;
Often the table is made by hand on the basis of wood. They are easier to assemble, which allows them to be made by a beginner;
Under the tabletop, the Bosch circular itself or its analogues is installed;
The disc should protrude above the tabletop. For this, a special slot is provided on the surface of the table;
Lumber moves across the surface of the table and is sawn cutting tool circular saw;
To increase the accuracy of processing, the table can be additionally equipped with a longitudinal and angular stop;
The tabletop will take away part of the working disk, therefore the sawing depth of the manual circular will become less by exactly as much as 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;
The desktop is recommended to be done with an emphasis on strength and subtlety. For these purposes, metal or durable wood species are suitable.

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

Tools and materials

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

To make a countertop, thanks to which a manual circular becomes a desktop, you will need certain materials and tools. This list includes:

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

Determine the dimensions at your discretion. But if the desktop circular is too compact, you will not be able to cut long workpieces on it with the required comfort.

When choosing dimensions, be guided by 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 cut lumber with your own hands using a Bosch tool.

Table top assembly

When everything is ready, you can start working with your own hands. Suppose that you have already chosen the Bosch power tool itself, or prefer an analogue of a trusted manufacturer represented by Bosch.

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

Taking a laminated plywood sheet as a basis, cut out a countertop from it corresponding to the selected size parameters. 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 the appearance of the future table. Using an electric jigsaw, cut off the excess, clean the edges.
turn the sheet bottom up, mark for mounting a hand-held circular saw. To do this, remove from your circular saw blade, place the soleplate against the surface of the sheet. Make marks on the sheet itself and the sole for future fastenings.
Use a drill to drill the holes needed for the 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, grind the bolt heads. So they won't show up.
If you are going to cut the material on the machine with a Bosch circular at different angles, a hole for saw blade a certain form should be performed - an inverted trapezoid. If only smooth cutting is planned, it is enough to cut out a standard type of groove.
Do not rush to immediately cut a hole according to the markup. Once again, take the circular, attach it to the sheet, check that the dimensions match, after which you can continue to work.
Use a pencil to mark where the stiffeners will be installed. To make them use wooden board. The ribs are located below, stepping back from the edge of the tabletop about 8-10 centimeters.
Tabletop legs are recommended to be mounted to the stiffeners. To fix the ribs, use self-tapping screws, screwing them with a screwdriver in increments of 15-20 mm. It will not be superfluous to additionally glue everything with PVA glue. Self-tapping screws must be screwed through the top of the desktop, while sinking the heads of the fasteners. Using long self-tapping screws, do not forget to connect the stiffeners together.
Using timber or boards, cut out blanks to create the legs of your design from them. The length can be 100-120 centimeters. Here you should focus on your own height, since it will be inconvenient for a high 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. Between them it is not superfluous to use washers. Having completed the screed from a bar, the frame of the desktop will turn out to be more durable.
You can adjust the height of the table with nuts that are screwed to the legs from below. M14 bolts are suitable for these purposes.
Now go directly to fixing the circular saw. Drive the disc into the slot made, and secure with appropriate fasteners.
From the inside of the table, it is recommended to screw the socket, connect the wiring to it and place the switch in a convenient but safe area. Drown the on-off button on the circular body and fix it.
Using 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, drill holes for the screws 30 mm from the edge of the tabletop. Using pieces of plywood, a pair of clamps is made.

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