A homemade mini circular saw will perfectly solve the issue of savings. Because not everyone home master in order to make minor repairs can afford to buy it. But sometimes you can't do without such a tool. A homemade circular saw that turns out can perfectly cope with the task associated with small construction, for example, in the country.

In order to make repairs at home or in the country, you need a circular saw, and you can do it yourself.

Circular homemade saw

A circular homemade saw is designed to saw logs.

The thickness of the logs that this equipment can cut depends on the power of the electric drive.

If it is necessary to cut thick blocks of wood, a shaft, a belt drive and the most powerful engine are placed on these saws.

Making the foundation

The mini circular saw must stand on stable table, because rocking can be dangerous and very disturbing in work. Before making a machine hand tool, it is necessary to build a special table. The bed can become old kitchen table or goats made of metal or wood. They must be connected to each other with a board with a cross section of 50 mm. A table is fixed on top of this base. One of the options for making a table top is to use 4 mm steel plates in the amount of 2 pieces. Another option is to use thick bars. They are tied in the middle with a jumper, for which they take plywood 20-25 mm. The required gap between the sheets is 10-12 mm.

It is very important to achieve perfect parallelism of the inner edges of the plate. Fastening the tool from below to the table will be carried out so that the circular saw is between the sheets of the tabletop in the middle of the gap. A mini circular saw is attached to the drilled holes on the table in this position.

It is quite possible to make a circular saw, or, as it is also called, a circular saw, with your own hands - there are several options for this at once. Everyone who is used to doing everything with their own hands, of course, knows how necessary and useful this tool is, especially for giving.

Not everyone can afford to buy branded equipment today, but this does not mean at all that you should start denying yourself everything and saving up for a coveted circular. There is a much more economical option: a homemade circular saw made by yourself.

Samu circular saw, as well as a table for her, can really be made with minimal cost for the family budget, that is, with your own hands, using improvised means. Of course, one cannot do without certain tools here, but let's talk about everything in order. First of all, we make a table for a circular saw. Here it must be remembered that the most important quality of the table is its stability, since swaying during operation does not just interfere. They are also fraught with a very serious danger: the circle of the saw is sharp, and it rotates at great speed. Therefore, in order to protect ourselves from unnecessary injuries and injuries, we pay increased attention to the stability of the table.

In order to make a table frame with your own hands, you can take it to some old table or to make a prefabricated surface - either from a metal profile or from wooden bars. For the bed, it is important that its surface is flat and preferably wide. The surface can be made from the following materials:

• plywood, plexiglass;
• fiberglass board;
• sheet of iron.

A combination of the above materials is also allowed. Here, as they say, at the discretion of the master.

Before making a table cover, you need to think about what kind of load it will have in the process of work, respectively, the thickness should correspond to the level of load. In addition, one more thing should be taken into account, it is enough important point- in some do-it-yourself circular saws, the drive is attached just to the table cover, so it is recommended to make it lifting. This option makes the design of the frame simpler, while making it easier for the master to access the power tool.

A corner is quite suitable as a guide bar: whenever you set the desired size, it will need to be attached to the plate with clamps. However, a more convenient option with a sliding bar is also possible here. If you stop at this option, then remember that the guide bar should be placed perpendicular to the plane in which the circular saw rotates, and the sides of the table top must certainly be parallel. A sliding sled can be made from an angle piece (aluminum or steel) that slides along the edges while maintaining a right angle. Some craftsmen make wooden sleds, but in this case, the machine bed becomes less durable and at the same time more cumbersome.

Bulgarian, drill and circular saw - choose options

Now let's go directly to the saw itself. You can assemble a circular saw with a powerful electric motor, a pulley system and a belt drive, but such a saw will be quite expensive. But there is more cheap option- almost everyone has such a power tool as a drill, Circular Saw or Bulgarian. On any of these tools, you can attach a cutting circular saw. In addition, their compact size can be attributed to their advantages here. Using such tools as an electric drive in order to cut not very thick boards is a very good solution.

It will be most convenient to use a circular saw, since it has the maximum size of the useful part of the disc, while a drill or a grinder, due to the design of their body, physically does not allow using the entire area of ​​\u200b\u200bthe disc. The power tool can be attached to the table with plastic clamps. Here you should also pay special attention to the reliability of fastening - an uneven cut will not be the biggest problem if the fasteners turn out to be unreliable.

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

A circular saw is used to cut timber evenly.

How to make a homemade circular?

In order for the circular saw to easily cut large logs, it is necessary to equip it with a truly powerful electric drive. In addition, for this purpose, a belt drive, a shaft and an engine with high strength traction. All handmade circular saws consist of two parts: upper and lower.

In the lower part there is always various electrical equipment, namely:

• saw motor;
• transformer;
• device that starts the circulation.

In the upper part of the circular saw set:

• pulley;
• cutting disc.

Large homemade circular saw

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

After that, two corners must be strengthened on the frame, on which the bearings will later be fixed. The distance between these corners directly depends on the length of the shaft. To fix the bearings, as a rule, clamps are used. It is best if the bearings mounted on a homemade circular are of a closed type. So you can not be afraid that wood chips will fall into the space between the balls, rings and separator. Don't forget to also cut the threads at the very end of the shaft so that you can later install a cutting disc on it.

The lower part of the circular saw should be made much more massive, which will provide it with the necessary stability and reliability. Therefore, in the manufacture of the lower frame, you need to take a corner with a width of at least 40 mm. Further across the frame, it is necessary to fix two more additional corners, on which the engine of a home-made circular will be held in the future. The most suitable motor for a do-it-yourself circular saw is an asynchronous three-phase motor with a power of at least 1.5 kW and 1500 rpm. The pulley creek should have enough big size, approximately 80 mm, and should be mounted directly on the shaft itself. In addition, you will need to weld a rather small metal platform to the frame, on which the launcher will be placed. Large pipes 2.2 m long, which were previously welded by you in the corners of the frame, are necessary for high-quality tension of the belt so that the metal lambs tighten the thin pipes.

Now, in the finished supports made of pipes, it is necessary to insert both the lower and upper parts of the homemade saw, and then tighten and tighten the belt with metal winglets. Starting the motor in this model of the circular with your own hands is carried out using starting capacitors. In order to load the motor and increase its torque, a 220/36 400 W transformer can be used.

Pendulum circular with electric motor

It is quite easy to make a homemade circular saw to cut logs and blocks of wood, the thickness of which corresponds to the power of the electric drive installed on it. If you intend to work with large and very thick pieces of wood, then you should equip your homemade saw a truly powerful electric motor, as well as install a shaft and a belt drive on it. best solution in this case, a special pendulum bed will be installed.

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

Base for mini circular

For the manufacture of such homemade products you will need:

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

The mini-circular should stand on a solid and stable table, since any rocking can be dangerous to human health and also interfere with normal operation of the saw. Before proceeding with the manufacture of a machine from a hand-held circular saw, it is necessary to make a special table. In this case, metal goats and an ordinary old kitchen table can be used as a bed. First you need to connect the goats to each other with a wide wooden board at least 50 mm thick, and then fix the kitchen table on this base.

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

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

In this case, it is necessary to ensure that the edges of the metal plates are perfectly parallel with respect to each other. Now that the table is completely ready, you can begin to attach the circular saw itself to it. It is important to note that it should be fixed from below, and in such a way that its cutting disc is directly in the gap between two sheets of the table top.
