A hand-held electric saw is a useful and convenient thing, but you won’t be able to work with it for a long time, since you need to make an effort. If you need to cut a whole tree or you constantly have to work with large volumes, then for this a circular saw is made from a circular saw with your own hands.

Advantages and features of the tool

A circular saw has its advantages: it allows you to make an even cut, increases the speed of installation, provides ease of use, saves electricity. If you replace the disc, you can overcome soft metal. To make a full-fledged tool for work, you need to install it on the table and provide access from all sides.

In this case, the following conditions must be observed:

• the table must be well reinforced, for which its legs are sometimes poured with concrete or bolted;
• the hand saw is fixed with iron brackets to the tabletop to ensure safety during operation;
• grounding is required.

Discomfort at work represents a large width table. The optimal size should not exceed 60 - 70 cm, so that it is convenient to hold the bar (not on outstretched arms).

If the work surface is not static, then the quality of the cut deteriorates, so fixing is necessary. The wire can be fixed with staples in the floor so that you do not accidentally stumble during operation.

As an option - make an additional outlet under the countertop.

First you need to prepare a drawing with an indication of the dimensions. It's almost a blueprint, but simplified. On paper, you need to indicate the amount of clearance for the disk - in width and length, where it should be in relation to the edges of the table. You can immediately imagine your work behind such a device.

Required accessories

Of the additional tools you will need:

• for fasteners;
• pencil or marker for marking;
• roulette;
• sandpaper.

During the course of work, need a milling cutter.

To make a table, you need to prepare:

• 2 guide rails;
• bolts;
• sheet size 60/120 cm;
• blank for a table with legs (if any).

The bed can be made independently from ordinary wooden blanks fastened together with slats, or a ready-made sawing table, iron or wooden, can be used.

Description of the workflow

How a saw blade guide is made. To make the cut even, a guide ruler attached to the workbench will help.

The essence of the device is to prevent the sawing material from moving during operation.

The easiest option is to attach two profiles, one to the sole of the saw, the other to the saw table.

To do this, you need to pick up two pieces of pipe, you can use an aluminum square profile of different sizes. Pipes must be cut vertically with a grinder. You should get a design according to similarity rails when one part enters another.

Next, you need to measure a piece along the length of the table. Pre-cut a recess and plant a profile in it, securing it with bolts from the bottom side. A smaller profile is cut to the length of the sole and bolted on. The edges of the metal should be sanded so as not to interfere with smooth movement. It remains to combine both profiles and test the device.

How to make a workbench

A table for a circular saw with your own hands can be made from MDF, chipboard, thick plywood, wood, metal. Plastic material is not suitable.

Stages of work:

1. Measure the required length and width from a sheet of material.
2. Trim with a grinder and grind the edges.
3. Attach the tabletop to the legs of the table with bolts, for fidelity, you can use wood glue.
4. Level the top with a level, fix it to the floor with metal brackets or pour concrete.

Important! The tabletop is installed on the legs after fixing the saw.

A circular saw from a circular saw is attached from below to the table with wooden slats.

Prices for MDF

Description of works:

1. Turn the countertop over, mark with a marker and cut a hole for the disc.
2. Cut off the top layer in the shape of the sole to a depth of 0.7 mm.
3. Take two bars and fix the sole with screws parallel to the length of the table.
4. Fasten the sole perpendicular to the table with two more slats.

Attaching the circular saw to the workbench is ready. If you plan to work permanently, then you can equip the table with an additional emphasis. This requires an even beam along the length of the countertop. It is required to install it parallel to the saw blade, preferably in a recess, secure it with bolts. It is important to align the part well so that it is strictly parallel - the quality of the cut will depend on this, especially if you need to make furniture.

Shaft manufacturing

How to make a do-it-yourself circular shaft.

If a circular saw is assembled in parts with your own hands, the engine is taken from a washing machine, the discs are bought separately or removed from a non-working grinder, then you will have to think about how to machine the shaft.

It is not safe to make this important part from old pipes, since the disk itself will be attached to the shaft.

Do-it-yourself circular saw shaft make it hard. Here you need a professional turner, preferably not a beginner. First you need to choose a special 45th steel grade. The material is wear-resistant and elastic, specially designed for the manufacture of shafts, cylinders, gears.

For turning on a lathe, a double-sided mount is used. The part is first processed with a conventional cutter to give the desired diameter. Next, with a finishing cutter, all burrs are removed. A small allowance is left for final polishing with sandpaper to a mirror finish.

Grooves on the shaft are made with a grooving cutter, as indicated by the drawings. In the process of work, you can remove the part and try on components that will subsequently be mounted on it.

On the shaft you can install fasteners for:

• various cutters that can be useful when turning curly wood products;
• conventional circular;
• planer knives.

A do-it-yourself homemade circular saw is equipped with a motor from an old washing machine. It is necessary to connect a starting device corresponding to the engine power to it.

When installing electrical must be respected safety regulations:

1. Provide thermal protection for cases of voltage increase.
2. The switchboard must be installed on a material that does not conduct current.
3. If a metal frame is installed, then the electrical wiring should be well insulated.
4. If a home-made machine with a circular saw is outdoors, then the electrical assembly must be protected from water.

If it is difficult to conduct an electrician for a circular saw with your own hands, then it is better to turn to a professional so that the equipment works for a long time and without breakdowns.

miniature model

To work with plexiglass, plastic, laminate, a minicircular can be useful - a small design that looks like a stool with disk in the center y.

This model is designed for thin sheets of material and will not withstand heavy loads.

You can use the grinder by attaching it from below using the method described above.

For emphasis, you can attach a bar 2 cm high.

The legs do not have to be strengthened, because the device is planned to be transferred.

Note! The device copes well with thin soft materials, but the tree is difficult to work with, to work with it you need to increase the power of the motor.

The motor power on the microcirculator is small - up to 40 watts. The disk can be taken from a hand saw, but it is quite possible to use a prefabricated structure, where a threaded rod acts as a shaft - a construction stud. The disk is fastened with a nut screwed onto the thread.

Other accessories

Do-it-yourself various devices for a hand-held circular saw are easy to make. One of them is a regular bar that is inserted into the stop included in the kit. The standard stop does not allow cutting wider parts, as it is designed for a certain width, different for each model. To be able to increase the gap, it is required to insert a wooden part of the desired width and push her soles.

You can make a tool for cutting grooves, which can be useful in the manufacture of furniture.

A circular saw from a hand-held circular saw can be adapted for cutting at an angle. Both additional parts and the possibility of fixing the disk itself at the desired angle are used.

A simple device for trimming with a hand-held circular saw. It is possible to cut at a given angle.

The wedge auxiliary part is suitable for the production of round wood blanks for decorative purposes.

The end cut is used in construction for wood finishing of walls, which are subsequently varnished, leaving the transverse structure of the tree visible.

In order not to waste money on various devices for small jobs, you can try to think of a solution to the problem yourself and create a working tool from available materials.

Old hand saws, possibly with a non-working motor, are suitable for arranging a circular saw. You can design a workplace according to any scheme. By selecting parts according to power, it is possible to cut materials of various widths and densities. With the help of additional devices, you can organize a carpentry workshop and perform various operations without extra costs.

A stationary circular saw is an indispensable tool in the carpentry workshop - for those who do carpentry work for their own needs or make various items to order. Such a stationary machine is easy to use - especially long and monotonous. With him, the master's back is in a straight position, so he gets tired less.

Today, in stores, machines and tools are presented in a huge selection of models. However, for a simple carpenter, they are too expensive, so you have to look for other solutions to get out of the situation. One of such examples - the master made a stationary saw with his own hands, taking a manual circular saw. In what way he did it - see below.

List of required materials:
manual circular saw;
plywood 11 mm;
M-8 bolts with a furniture cap;
screws;
switch;
the wire;
timber 40x40;
furniture guides.

List of tools:
electric jigsaw;
manual circular saw;
drill;
screwdriver;
hammer;
screwdriver;
pliers;
ruler.

How to assemble a stationary circular saw

As we have already noted, the author used a manual circular saw to make his circular saw. At the same time, he made no changes to the design of the saw itself. In this case, the master made a table, attached the sole of the saw to the bottom of the tabletop - where the cut for the disk had been made before. He drilled holes and then sawed through. Taking plywood and timber 40x40, I made a base.

After that, the author took plywood, sawed out the countertop. It is better that it be laminated or varnished, with a flat and smooth surface. As described, a cut was made, holes were drilled in the corners for subsequent fastenings.

At the bottom of the tabletop, we fasten the circular saw using M-8 bolts. In this case, the bolt heads must be recessed into the plywood.

The author installed and connected the switch, fixed the start button on the saw in the pressed position, and connected the switch to the outlet. Therefore, you do not need to disassemble the saw, and connect something to it, too.

For more convenient work with the machine, the craftsman made a movable emphasis on furniture guides.

An aluminum corner served as a longitudinal stop.

To adjust it, loosen the bolts and move it to the distance necessary for further work.

For greater convenience, a hand-held circular saw can be mounted on a table. This design will help you quickly and easily process and saw wood parts.

Working with a circular saw mounted on a special table greatly simplifies the sawing process and is safe when using special devices.

In this article we will tell you for a hand-held circular saw with your own hands.

Circular saw table design

The table base for a circular saw can be wood or metal.

The tabletop is made of metal or sheet wood materials. A hole is made in it for a circular saw blade.

Supports run along the guides in the tabletop, which move the timber and any other sawing material.

First of all, the table should be comfortable, stable (do not stagger!), The surface of the tabletop should be flat. These factors will help a person avoid injury during work.

The hole in the base is cut for a specific brand of saw

Before you start cutting the material and assembling the circular table, you need to calculate its dimensions and make a drawing.

The hole in the base must match the dimensions of the circular saw platform. For each brand of saw, this will be a specific size.

The plate installed on the countertop should not outweigh the table in one direction - the base must be resistant to external mechanical loads.

The dimensions of the countertop must match the flow.

For some, a folding table is enough, a small table with a removable circular saw. People who have a spacious workshop need a full-fledged table for a circular saw or even a circular machine.

Note: if it is planned to leave materials on the table during work, then the area of ​​\u200b\u200bthe countertop should be at least a square meter. The optimal size for such a table is 120 x 120 cm.

Materials from which you can make a table for cutting wood:

• solid wood;
• Chipboard, chipboard, MDF, plywood;
• metal (steel or aluminum).

Plastic is not well suited as a material for making a saw table.

Prior to final assembly, all wooden parts of the table should be protected from moisture and decay.

To make a saw table with our own hands, we need the following materials:

• Chipboard or plywood 21 mm thick;
• timber for the table frame (you can use a edging board 50 x 150 mm 3 meters long - 5 pcs.);
• wooden dowels 10 mm - 12 pcs.;
• joiner's glue;
• metal fasteners for the sides and legs - 4 pcs.;
• metal corners - 10 pcs.;
• self-tapping screws.

Necessary tools for work:

• pencil, marker, tape measure, meter;
• jigsaw;
• manual ;
• Sander;
• sandpaper of medium and fine grit;
• plane;
• drill;
• screwdriver

Step 1. To begin with, we trim all sides of the beam with a planer. We assemble the frame of the table from the timber: on each side of the tabletop we drill two holes of 5 mm for dowels for each side and one hole for each table leg.

Step 2 In the sides you need to make two holes (5 mm), and in the legs - one each (5 mm).

Step 3 We install the dowels in the countertop, after lubricating them with wood glue. From above, the tsargs and legs are installed.

If there are clamps with ties, you can fix the table with them. After the glue has completely dried, the sides are fastened to the legs and to each other with special metal fasteners for tables and pulled together with self-tapping screws.

Note: the table will be stronger and more stable if you use metal corners for additional fastening of the tabletop: two on the short side and three on the long side.

Step 4 Now you need to fix the circular saw on the inside of the tabletop. There can be two options here: fasten the saw platform with M4 bolts or fasten the platform using bars with self-tapping screws. The first option is faster and more reliable. The second option does not require drilling holes in the metal platform for bolts.

Step 5 You can fix the saw with bolts or bars with self-tapping screws. We will fasten with bars, so in small bars we make a drink as wide as the saw platform. With bars with self-tapping screws on both sides, we fasten the circular saw to the tabletop.

Step 6 When the saw is installed, we take another larger bar and fasten it to the tabletop with self-tapping screws (directly to the points marked earlier, along which the saw platform was set evenly). This bar is necessary so that in the future, when removing the saw from the table, you can quickly return it to its place without resorting to marking.

Step 7 We install the circular saw blade in place and saw through the countertop to make a longitudinal hole. Flip the tabletop.

Step 8 We make a parallel stop. To do this, we saw off two strips from plywood with a length equal to the width of the table and a width of about 8–10 cm. We round the corners with a protractor and a pencil.

Step 9 We grind both strips and fasten them with self-tapping screws at an angle. Inside we fasten the metal corner.

Step 10 With constant work with a table for a circular saw and the need to fix the stop on the tabletop, a guide is fixed perpendicular to the disk. The roller or the second part of the guide is attached to the bottom of the stop so that the stop can drive up / drive away from the circular saw blade.

Workplace safety

In order not to be injured during work, it is necessary to carefully monitor the position of the saw table, its stability, strength.

Before each switching on of the circular saw, it is necessary to check whether it is well fixed in its place.

It is strictly forbidden to hold the cut material with your hands! This can lead to injury to the fingers or the tree bouncing in the face if knots and bumps get into it.

Also, be sure to wear protective goggles during operation to avoid injury to the eyes.
Do not neglect these simple rules, take care of your own health.

For more information on how to make a table for a hand-held circular saw with your own hands, see the following video:

The vast majority of repairs and dacha work require a good carpentry power tool. Often, in home carpentry, it is required to dissolve massive lumber into a rail or planks. You don’t run into a stationary circular to your neighbors, and a hand-held circular saw is inconvenient for these purposes. Therefore, most DIYers sooner or later come to the idea of ​​making a stationary circular saw for themselves with their own hands from improvised materials.

Working conditions of a circular saw for wood

A circular saw is necessary, first of all, in order to make a long cut in a solid wood, accurate and even, like a stretched string. It is possible to ensure high cut quality only by fulfilling three conditions:

• High speed of the cutting edge of the saw. Ideally, you can get a cut quality comparable to a surface ground with emery cloth;
• Sharp cutting edge of a circular saw tooth. Some brands of discs are made from high speed steel, but it is best to use a carbide-tipped tool;
• High rigidity of the "circular saw blade - desktop" system. The higher the rigidity, the more accurate and smoother the cut line will be.

Any saw with a working tool in the form of a toothed disk poses a serious danger to the worker, so they try to make the table for a circular saw with their own hands as durable and convenient as possible.

For your information! In industrial circular saws, large-diameter discs are used, up to 60-70 cm, so the motor speed is relatively small - 800-1200 rpm. In a home circular, the size of the cutting disc does not exceed 25 cm, so the rotation speed is required quite high - up to 10,000 rpm.

Circular manufacturing options

You can build a circular saw in a home workshop according to one of four schemes:

1. Install an asynchronous electric motor of 1.0-1.5 kW on a table welded from metal, make a step-up belt drive on the shaft, on which a cutting disk is fixed with a flange;
2. Make a small wooden table for a low-power engine from a washing machine;
3. Install an industrial hand-held circular saw on a machine assembled from a wooden beam;
4. Use an ordinary angle grinder as a drive for building a circular, in which the abrasive disc is replaced with a steel cutting tool.

All these schemes are used in practice with different efficiency. If you want to dissolve thick, up to 100 mm thick beams and logs, then you need a circular saw with a powerful engine and a steel frame.

An angle grinder is well suited for trimming small parts made of wood, but it is practically not used for a stationary circular saw due to the limited time of continuous operation. A relatively weak and uncomfortable circular saw is obtained from the engine from the washing machine. Low power - 500 W and low speeds require the manufacture of a step-up V-belt drive and a system of two shafts. There is a lot of trouble, and the quality of the cut and the productivity on such a circular are low.

Building a home circular

According to the reviews of many home-made carpenters, the easiest way is to convert a manual circular saw model into a stationary one, or, more correctly, an easel one. In this case, you can kill at least three birds with one stone:

• Firstly, hand-held circular saws have high rotational speeds, which means that a good cut quality is ensured;
• Secondly, in a commutator motor, the shaft is mounted on bearings designed for radial load;
• Thirdly, the cantilever mount of the cutting disc allows you to relatively quickly replace it with a new one, without disassembling the circular saw.

For your information! The main advantage of the above circular saw circuit is the well-chosen engine torque and its speed, which ensure maximum machine performance.

On a 225 mm disc, the overhang or height of the disc above the work table is only 40 mm. This is more than enough to cut a forty board into a plank or rail, cut out any curly details and solid wood. In addition, a spring-loaded protective cover is installed on the body of the circular, covering the cutting edge in the non-working position.

Perhaps this device is useful and necessary to protect fingers and hands, but it only interferes with work, since the thin cutting edge of the disk is not visible. Therefore, when reworking, it is often dismantled or fixed on the body of the circular saw in the open position.

Converting a hand-held circular saw into a stationary version

All that needs to be done to convert a hand saw to a stationary version of a circular saw is to make a table or a box-shaped case and fix the saw on the reverse side of the table top so that part of the cutting edge of the disk protrudes above the plane of the table, photo.

The size and shape of the table for the circular is chosen based on the width and length of the lumber. For small boards, a one and a half meter table, 60-70 cm wide, will be optimal. The supporting part of a circular saw can be welded from a steel corner with a shelf width of 25-30 mm. In the upper and lower parts of the legs, horizontal spacers are welded from reinforcement or a corner. This solution allows for maximum rigidity of the frame.

For countertops, you can use laminated chipboard or OSB, plywood 15-20 mm thick. At the same time, the countertop itself does not have to be placed symmetrically with respect to the steel support frame. When cutting a board on a circular saw, you have to work with two hands. With one hand, the material is longitudinally fed forward, and with the other we press the board to the table. So, the main thing is that the location of the motor and the pressure point are not very close to the edge and do not create a tipping moment for the entire structure.

The plane adjacent to the cutting tool can be covered with metal or plastic to make it easier to move the solid board on the table of the circular saw.

The only drawback of such a remake is the need to remake the controls: the start button and the hold lever. Most hand-held circular saws, in addition to the start button, are equipped with a lever or hold trigger. While you press the trigger to the saw handle with your fingers, the engine of the device is operating in normal mode. It is worth releasing the trigger, as the engine stops. A very necessary thing if, while cutting, you suddenly dropped a working circular saw from your hands.

Therefore, the first step is to make changes to the control system of a hand-held circular saw. To do this, the contacts on the button and the trigger are output to an external electric bag fixed on the body. Of course, such alterations can be performed for power tools for which the warranty period has long expired.

In rare cases, it becomes necessary to remove the tool from the table and use it in its original manual version. In this case, instead of soldering the contacts, the button and the trigger are fixed with a clamp or simply wrapped with electrical tape, and the power cord from the tool is included in the carrying with the on-off button.

The simplest version of the conversion of a circular saw is shown in the photo. For a table circular saw, a case in the form of a box is made of plywood. The tabletop with the installed circular saw is turned over and fixed on the box.

Making a guide line

When working on a circular saw, it is important to be able not only to cut the board, but to cut a plank or rail of a given width exactly to size. To do this, a guide ruler is installed on the saw table, which can be moved relative to the plane of the disk, and thereby select the cutting width.

The ruler is made in the form of a steel corner. With the help of screws, the ruler can be relatively easily moved along the slots in the table top, and thereby change the size of the cut.

A simpler version of the ruler is made from a pine board, 40 mm wide and 20 cm longer than the table size. Along the edges of the board, two furniture nuts with a metric thread are pressed into the lower part. With the help of screws at the ends of the ruler, L-shaped hooks are attached. After installing the ruler, the hooks are tightened with screws, the hooks rise and firmly fix the guide bar on the table top.

Conclusion

Naturally, the capabilities of the commutator motor of a hand-held circular saw are not designed for a serious load. On such a machine, you can cut a couple of dozen strips, after which the engine must cool. The total service life of the motor is 50-70 hours, after which it will be necessary to remove dust, clean the collector from soot and replace the brushes. But, in any case, the possibilities of a circular saw are enough for homework.

For any home craftsman, having their own stationary sawing machine is time saving and safe work.

You can buy a ready-made stationary circular. The cost of small machines starts from 9,000 rubles, more or less decent stationary saws are sold in the price range from 30 to 100 thousand.

Despite the apparent complexity of the design, any craftsman with elementary locksmith skills can make a homemade circular saw. Moreover, during the design process it is possible to add functions that are not provided by the manufacturer.

What is a circular saw for?

Before starting work, it is necessary to determine the main tasks of the sawing machine. If you just need to cut firewood for the winter, or do basic carpentry work like making a fence, a sturdy table with a slot for a saw blade is enough. Such options are popular in rural areas.

Circular for working with logs

Of course, there can be no question of any safety and functionality when using such a device.

In some of these "models" there is a shaft for fixing the knives of a planer or jointer. As a rule, a bed is cooked from a corner or a channel, an electric motor is fixed on it from a decommissioned factory ventilation, and with the help of a pulley, the torque is transmitted to the disk. It makes no sense to describe in detail the manufacturing technology of such a machine.

Another thing is if you want to do carpentry work. In this case, you need a coordinate table with guides that are fixed at different angles.

Since such a stationary saw can work with small workpieces, it is necessary to take care of the safety of the operator. It is desirable to provide for the adjustment of the rotation speed and the possibility of easy change of discs with different diameters.

Be sure to install a protective cover over the disk, and cover the rotating parts of the drive with covers. The starting device is equipped with an emergency switch, and the stop button is placed in an accessible place and is made large.

How to make a circular, keeping a balance between economy, functionality and safety

Consider the main components that make up a home circular saw. You can make them yourself, but with certain skills and tools.

The frame can be made from a metal corner (channel) purchased from scrap metal collectors. If you have the funds, contact the metal rolling warehouse. Legs can be made from old water pipes, connecting them with corners.

A good option for a homemade frame made of rolled metal

IMPORTANT! The use of bolted connections is prohibited, because due to vibration, such a mount will unwind.

Electricity must be used. Be sure to reinforce the corner joints with a jib. The upper part of the frame (on which the table will rest) and the podium for the electric motor are made from a corner with a side of at least 50 mm.

If the machine is equipped with wheels for movement, they must be with steel rims and have locks. The higher the mass of the bed, the more stable the machine will be, and the safer the work will be.

What to make a table for a circular saw?

The working surface is made of steel, duralumin or silumin sheet. It is permissible to use textolite, plexiglass or moisture-resistant plywood. Galvanized sheet is stuffed over plywood.

The main condition is that the material should not crack from vibrations., have a smooth surface and prevent deflection under a weight of at least 50 kg. If the countertop cracks or warps, the circular disc will jam.

This will lead to injury and damage to the workpiece. The use of popular OSB and chipboard materials is undesirable. These materials are unstable to vibrations, and can collapse at the most crucial moment.

There are two options for making a working groove for a circular disk:

1. You can cut a groove.
2. or place the two halves of the countertop at a distance from each other.
