Stationary installation of a circular saw with your own hands. Description of equipment

Circular saw

To make a high.quality structure, you must observe some tips. The process consists of several steps presented in the table.

The design is made and ready to use

When performing the described manipulations, it is important to remember the observance of safety measures. Applies and any manipulations with a disc saw

Regularly check the position of the table and its fortress. The design should be stable, without loosening.

First make sure the saw relieved to fix it, only then turn it on. You can’t keep the material with your hands. This will help to avoid wood in the face when the knots begin to bounce. Additionally, it is recommended to use special protective glasses when working.

For safety, be sure to use goggles

These simple tips will help to avoid injuries at the workplace.

The design of the circular machine

Before thinking through the design of the upcoming machine, you need to calculate the load that it will be subject to. The main thing in the bed is reliability and stability. For powerful production saws, the base is a welded reinforced metal structure. But for your own use, such an unit is not needed.

If you just decide to make your woodworking machine, then you need to consider the main parameters of the equipment. Since saws can be different, of course, the design of the bed can be different.

First of all, you need to determine the power of the tool. As a rule, for home use, they choose equipment where power parameters do not exceed 850 watts. But, for example, during the construction of a cottage or a country house, you often need to cut a very large amount of wood.

That is, the power of the circular is required more. But experienced masters do not advise buying saws where this indicator is more than 1250 watts. The installation of this equipment in a home workshop is absolutely not justified. And work on it will only increase the cost of electricity.

The greater the productivity of the machine, the more stable for it you need the base. For professional circulars, as a rule, a base is installed cooked from a steel profile. Sometimes these beds are even concreted in the floor. Since the vibration of the device can lead to life danger.

Technical features of circular machines

The depth of the alleged cut. The thickness of the material that will be processed on your machine depends on this parameter. This indicator in semi.professional and professional machines fluctuates in the range of 5-8 cm. For the cut of boards and thick plywood, this is quite enough.

But working with logs on this machine will already be inconvenient. In addition, it must be taken into account that this characteristic in a homemade saw is reduced. The cut depth will be less than 1 cm. But this can be avoided if you provide in the table of the table the ability to lower or raise the disk.

In the manufacture of the tool with your own hands, you need to take into account the frequency of its rotation. If you need a circular for harvesting building materials, then this indicator may be less. If a clean and even cut is needed, then the speed of rotation is needed quite high. This is necessary, for example, for the manufacture of furniture.

But in this case there are certain nuances. This saw is not suitable for cutting plastic materials. Due to the very large revolutions of the tool, the disk is warming up, and the plastic begins to melt.

Therefore, it is better to choose a device where the rotation frequency is not more than 4500 rpm, in this case, the bed for a circular saw can be made of wood. The vibration of this machine is low and additional strengthening of the table is not required.

Well, at the end, what needs to be provided, this is the location of the buttons and the remaining controls on your machine. When assembling a saw with your own hands, do not forget that access to the control panel must be safe

over, this rule is important when the open part of the saw is below the countertop

In this performance, the panel with inclinants is best placed on the outside of the machine or make a rising countertop. A similar design is convenient for servicing the device. Then, when you took into account all the nuances and trifles, you can start direct assembly of the table.

We town a circular machine from a manual circular ⁠ ⁠

I needed, the other day, a circular machine. And he, quite by accident, was not at hand. To give more than dozens (the most minimum for the chapa China) does not allow the lean amphibian, but the need does not get less. There are, of course, liners-figobziks, but this is not a solution, because, you need, some kind of performance and accuracy. I had to harness ingenuity and hard work.So, we have a manual circular, a decent piece of 15th plywood, a piece of corner, all kinds of nincess bolts, drill, and manual (not wild) milling. Three or four more completely unlucky hours. Which we have to take on the handwritten (Elya Pala, my Android knows the word “handwritten”. Where would be from?).Further more text than pictures.In stock we have a slightly.contested wrapping plywood, which allows you to get a rectangle of 1000x700mm and a thickness of 15mm. And, first of all, we get it, using the jigsaw.Next, we cut out a rectangular hole with a jig. And along the contour, a milling mill, select a recess that will give a drowning table on a flush with a plane of “fanerki”. Riding tears, we fly a 5m drill several holes in the circular table (and in Fanerke). which will allow you to fix the circular on the sheet. Do not forget to brown the hole in order to completely immerse the screw head into it (do not be afraid, most likely, the table of the circular of the slightly resistant and strong.and.fit luminium). Yes, this will not harm the circular (uh, I hope).Thus, we have a circular plywood fixed in a piece.

Thus, we have a circular plywood fixed in a piece.But we still lack the stop to saw as it should, and not as we have to. Well, we take a corner from structural iron at hand (and finally, you can also a piece of wood) and score emphasizers from it.In the sheet of the fanerki we make slots using a drill and a jigsaw.

The desired machine is ready?Yeah! Screw the trigger trigger with wire and can be sawed!Well, yes! The current is dumb. Since you can turn off the paluser only by pulling out the plug of the circular from the outlet.Not suitable! Losing consciousness from shock because of the fingers flying towards, it is not quite comfortable to remember the outlet. Otherwise, I lie on the floor, pouring it with my liquids, and the circular continues to spin cheerfully. The switch should be simple and quickly available!Oddly enough, the switch, outlet and meter of the two.core wire are at hand.

This, of course, is not ideal, from the point of view of functionality, and security (what already there), but, to the extreme, will come.Yes, photographed on a corner grinder.III, also take care of your fingers, please! Circular. The most cheerful instrument in this regard (except for a corner grinder with a saw disk. But this is for heroes, strong in spirit!)))

Scheme for the manufacture of 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 facilitate the process of creating a design. First calculate the dimensions of the table, then transfer the received data to the paper. The hole performed in the structure should definitely approach the size of the saw. It all depends on the brand of equipment. Therefore, you cannot make a universal hole. The base should be stable and well withstanding mechanical loads.

DIY circular drawing

The outburst of the structure into one of the sides is unacceptable. The dimensions of the countertops should be suitable for the flow of sawing. The final option is revealed 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 be taken into account an important point. If the plans to leave tools or materials on the table when working, then the dimensions of the countertop should be increased to a square meter in the area. A suitable size will be 120 by 120 cm. The drawing should be done carefully and slowly to do everything competently.

Advantages of homemade technology

Home.made circular circus are very popular due to the simplicity of their manufacture, durability and reliability. Today, many summer residents use homemade units, and do not buy expensive equipment in specialized stores.

The main advantages of such technology include the following:

• The universality of the tool.
• The simplicity of its manufacture.
• The possibility of significant savings.
• Reliability and durability of equipment.

The schemes of stationary and mobile circulars available on the Internet and thematic printed publications allow you to make equipment for processing both thin blanks and thick lumber. You can choose the simplest options that do perfectly with processing the lining, thin lamella and plywood.

Miniature engine from a washing machine

The circular is extremely simplicity and availability of materials for its manufacture. Perhaps the only expensive detail is the electric motor. Stationary machines are equipped with a powerful asynchronous engine, which provides a cut of thick wood of any species, but in a home workshop you can limit yourself to a lower power.

note! For sawing boards of medium thickness, it is enough to make a circular table with a drive from the engine of the washing machine with your own hands.

This design has several advantages. The engine from the old washing machine is inexpensive, moreover, such an unit will probably be found in the household of a house. Connecting this engine is not particularly difficult, there is no need to look for a scheme, to solder. With all this, the power of such an unit is enough for most types of work.

The machine diagram can be simplified as much as possible by excluding belt transmission. In this version, the cutting tool will be attached directly to the engine shaft. A frame of a desktop mini-station will serve as a frame assembled from a bar with a cross section of 40 x 40 mm. If desired, it can be welded from the corner or profile pipe.

As a stand (countertops) of the circular, part of the body of the old TV, a coating boat, is ideal. As practice shows, this part is characterized by sufficient strength, and thanks to the lacquer, it does not prevent the glide of the workpiece.

In the countertop, an electric shutter is perpendicular to the cut under the disk, two parallel cuts are made. A mobile square playing the role of lateral emphasis will slide on them. He will help to make a flat cut, if necessary, at a given angle.

Stationary machine

Those who plan to seriously engage in woodworking should think about the manufacture of a full.fledged stationary circular saw. This should be a separate unit installed on a workbench equipped with a powerful engine with the possibility of fast disk replacement. For the manufacture of such a circular will have to spend time, but it will definitely pay for herself.

Despite the apparent simplicity of this device, before starting work, it is worth creating a drawing machine. This will clearly see the future unit, choose its optimal configuration.

Stanin

The basis of any machine is a bed, a frame on which all the main details are mounted. The bed of circular should be stable and reliable, so it is made of metal. It is preferable to use a profile pipe or thick.walled square. Welding is used to connect parts. If the collapsible design is conceived, the connection on the bolts is suitable.

Buying suitable material will not be difficult, in any specialized metal rolling store you can choose pipes and a square. Those who wish to save can be recommended to contact buyers of scrap metal. You can buy the same thing from them, only cheaper.

Countertop

The best material for the manufacture of a professional circular counterattack is metal. Steel and aluminum.based alloy. For the budget option, you can limit yourself to thick multilayer plywood, upholstered in leaf iron. In any case, the surface of the countertop should be smooth, resistant to friction and not bend under a weight of up to 50 kg.

In the countertop, a groove is made under the disk. It can be done in two ways. You can make a drink in a whole sheet, or you can assemble a countertop of two halves. The second method is preferred for a metal countertop, it was difficult to drink in at home.

Parallel emphasis is attached to the countertop. The best material for this, regardless of the material of the table, is a steel corner. For its fastening, grooves are made or powerful clamps are used.

Motor

The engine of the future circular is selected depending on the available disk. If you plan to work with small disks with a diameter of 150-170 mm, you can limit yourself to an electric motor with a capacity of about 0.5 kW. For discs with a diameter of 350 mm, you need to look for an unit of 1 kW or more.

If desired, you can make a sawing machine for work outside the workshop, for this it is enough to provide the ability to install a small.power gasoline engine, it can be removable.

Transfer of rotation

The optimal circular drive is a cunelar gear. Two pulleys are used, one on the engine, the second. on the drive val. It is convenient and safe. There is no direct connection between the engine rotor and the disk, in the case of jamming the tool, the belt will begin to slip, signaling the need to turn off the power. In addition, using pulleys with several streams, different diameters, you can adjust the speed of the saw, choosing the optimal mode for various wood.

Rotation from the engine rotor is transferred to the shaft. This is one of the most important details of the circular. It is unlikely that it will be possible to make a shaft yourself, it is better to buy ready.made or order from a turner.

The shaft is installed on the bearings. They should be closed type: Circular. the place is saw and open for a long time will not last.

Tips and safety precautions

In the course of work, you should adhere to the recommendations of specialists.

• You can not work with wood, in which there are metal fragments (nails, screws, etc. D.);
• Marking the material is possible only in the presence of special latches or substrates (especially for long boards and timber);
• Boards and a beam from two meters long should process two people;
• When working with the disk, sudden movements or shocks should not be used, otherwise. the device can jam, it may break;
• If the material has dimensions from 42 cm, then it is recommended to use a special pusher;
• If the wood is heterogeneous (there are branches and nodes), then it is necessary before work to dissolve;
• You should always use gloves: both during operation and during the cleaning of the unit;
• You can not accumulate wood waste on the machine. this can cause a fire or short circuit.

You can’t work on the machine under the following circumstances:

• no guide tire;
• There is no casing;
• too wide gap (from 10 mm);
• There are no fuses (a crumbling cutter, delaying fingers) who protect the employee from a broken workpiece;
• The height of the crumbling knife exceeds the height of the saw disk (from 6 mm), the distance of its installation (17-110 mm).

A collector of shavings should be present on the machine. During operation, you should definitely use the protective glasses. When changing the elements on the machine, it should definitely be de.energized.

About how to make a circular saw with your own hands, watch in the next video.

The choice of dimensions

Choosing the size of the sawing table is worth it depending on the quadrature of the workshop. A small area of ​​the room allows you to use a countertop 50 x 50 cm. It makes no sense to make a sawing table less. it will be difficult to use it when processing long blanks. A universal size that provides convenient sawing laminated wood-bearing plate-80 x 80 cm.

The maximum recommended dimensions of the sawing machine is 120 x 120 cm.

To comply with safety requirements, it is recommended to place the saw in the middle of the countertop at a distance of at least 25 cm from the edge. it is this indicator that leads to a minimum width of 500 mm. The location of the sawing disk also depends on how it will be used. There are three varieties of structure in total:

The depth and location of the disk installation depend on the workpieces processed on the machine. For boards and plywood, he should protrude 50–80 mm above the countertop, for logs. 110–125 mm. The height of the upper part of the frame from plywood sheets or laminated wood-based plate can be in the range of 35–40 cm. If you make a bed only from the beam, this parameter depends on the section. The remaining part of the structure is wooden legs, the size of which masters usually choose under their height. The total height of the sawing table is about 1.0–1.1 m, but can decrease to 900 mm.

The advantages and features of the tool

The round saw has its advantages: allows you to make an even cut, increases the installation speed, ensures ease of work, saves electricity. If you replace the disk, you can overcome soft metal. To make a full.fledged tool for work, you need to install it on the table and provide an approach from all sides.

In this case, the following conditions must be met:

• The table should be well fortified, for which its legs are sometimes filled with concrete or screwed with bolts;
• The manual saw is fixed with iron brackets to the countertop to ensure safety during operation;
• Grounding is necessary.

The inconvenience during work is a large width of the table. The optimal size should not exceed 60. 70 cm so that it is convenient to hold the bar (not on outstretched hands). If the working surface is not static, then the quality of the sawing is deteriorated, so consolidation is necessary. The wire can be fixed with brackets in the floor, so that during work, do not accidentally stumble.

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

Previously, you need to prepare the figure of the countertop indicating the size. This is almost a drawing, but simplified. On paper, you need to indicate the size of the gap for the disk. along the width and length, where it should be in relation to the edges of the table. It will be possible to immediately present your work for such a device.

“Circular from the circular

Among the self-taught carpenters, it is believed that the transformation of a manual circular saw into an easel tool is the simplest method of obtaining “three hares” at once, namely:

• high quality cut, guaranteed by high rotation of the saw;
• shaft installed in the collector engine on bearings, with the honor of withstanding the radial load;
• Ideal (console) disk fastening, it makes it possible to relatively quickly replace the cutting tool, so the circular disassembly is not required.

The main advantage of the manufacture of such a machine is a “native” engine that guarantees a maximum performance due to the perfect rotating moment, the optimal turnover. Other advantages of this solution:

• Relatively simple fixation that allows you to quickly remove the saw in case of great need.
• A powerful engine that provides long work due to the ability to withstand significant loads.
• Normal thermal regime that guarantees forced ventilation of this manual tool.
• The ability to get a sufficient cut depth using large diameter discs. 60-75 mm-a value that gives a good chance to make high-quality blanks for various products made at home.

Stanin and countertop

Alteration of a manual saw into a circular machine begins with the manufacture of a table (or hull-hull), on the back of which the manual power tool will then be attached so that part of the cutting edge protrudes above the surface of the countertop.

The shape and size of the table is chosen, focusing on the dimensions of future lumber. If they plan to make blanks of small sizes, then there is enough length of 1500 mm, width-600-700 mm. For the manufacture of the bed, the circular is suitable for a steel corner with a shelf width equal to 25-30 mm. From above and below, the structure is enhanced by spacers made of the same corner or reinforcement. This option is optimal to provide the machine frame with maximum stiffness.

For countertops, a laminated wood-and-scale stove or OSP is more often chosen, some masters stop on the faner, the thickness of this material is 15-20 mm, but you can take a thinner material, and then connect 2 sheets together. The elements that make up the countertop should not have the same size at all, to have a symmetrical location relative to the bed. The main thing is that the structure does not threaten the risk of overturning.

In the countertop, they make a backwater designed to extend the disk. That part of the surface of the table that will fit the cutting tool is often closed with tin, a metal sheet (aluminum, steel), textolite or plastic. This solution makes it possible to maximize the movement of wooden lumber as much as possible.

Modification of saw management

Such operations can only be performed in one case: if the tool has the warranty period. For the convenience of controlling the circular machine, the contacts of the buttons and the shredt (lever) are displayed to the external electric circuit breaker, which is mounted on the case in a convenient place, but where random presses are completely excluded.

If the owner provides in the future the opportunity to periodically remove a hand tool, then the contacts are fixed with electrical tape or a clamp. Circular cord in this case is included in a carrier equipped with a switch button.

The guide line

It is necessary for the exact cut of material of different widths, so this line (emphasis) is obliged to be able to move parallel to the cutting edge. Such an element is also made from a steel corner. The countertop makes slots in which the ends of the guide are attached with the help of screws.

A simpler option is a pine board. Its width is 40 mm, its length is 200 mm more than that of the table. First, the nuts are pressed into the lower part of the protruding edges, and M-shaped hooks are fixed with screws. After installing the board on the countertop, the circular are attracted with screws, thanks to them the hooks rise and reliably fasten the ruler. It can also be easily moved to any place.

Circular grinder

This option of manufacturing a machine is more popular, since a rare owner who loves to do everything does not, or is not going to purchase in the near future, a corner grinding machine. The first of the stages of the manufacture of a stationary saw installation is also the manufacture of a special table for fastening the corner grinder.

In this case, the process is complicated, since the main difficulty is reflection on how to attach an angular grinder to the bed: how to make a sliding emphasis and an axial handle. However, there is already a ready.made way that allows you to get a reliable connection.

• Two segments of a steel corner are taken to make a sliding stop. They attach them on both sides of the sawing disk. Then they are connected by a transverse connection (bolts and nuts). Wages are used to ensure the necessary gap.
• Previously, a metal strip clamp is pulled onto the tool, its screw screed should be below. The metal strip, doubled, is attached to the holes designed for a sliding stop.
• In the gearbox, the corner grinder makes several holes for the bolts: first the housing is disassembled, then indicated points for drilling. With their help, an axial handle will be fixed. This element is made of a rod or metal pipe. The handle gives the form of the staple. At the ends. in the places of fasteners to the gearbox. the holes are drilled.
• Make a barbell, obliged to regulate the depth of the saw. It is made from a piece of a metal rod. The loop is formed on one side, then it is slightly rumbled, drill a hole designed for a stubborn bolt. The thread is cut at the other end, they first wind up one reliable nut, and after assembling the structure. the second. Adjustment of the cut depth will occur when they are pulled up or weakened.

Not too complex actions will make it possible to get a full.fledged circular machine for cutting different materials. They come in the same way with a drill, which can some extent replace the corner grinder. To avoid potential mistakes, it is better to use drawings that every “suffering” can find on the Internet if desired.

Making countertops

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

Upon completion of these operations, the surface of the countertop is carefully processed (grinned) with an emery skin of medium granularity.

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

For the convenience of marking the countertop, the saw disk is removed

At the end of its preparation, you should take a circular saw and try on it at the installation site. If necessary, the position of the points of its fastening is adjusted (at the same time, the contours of the slot under the saw disk are clarified).

The finished countertop from plywood is closed with a steel sheet mounted on it using self.tapping screws. It will subsequently apply a special marking to the working surface, which allows you to adjust the position of the wood blank in the process of processing it.

How to make a shaft for circular with your own hands

In the overall design of the Circular, the shaft is the main element that forms the machine as a whole. For its manufacture, you will need a steel circle of the brand 45. Just make this important detail on your own only if you have your own current machine or access to it is possible. The diameter of the workpiece should correspond to the size of the saw discs, which are supposed to be used.

The main sizes of the landing opening of the discs:

From the above indicators and the size of the shaft for the circular is selected.

For the manufacture of the shaft, you will need a steel circle of the brand 45.

The most common is the diameter of the hole 32 mm. It is such a planting nest that have discs with different sizes of external diameter. As an option, you can make a thinner shaft so that there is an opportunity to perform a “jewelry” job. Then, to use large discs, an adapter will be used. It is worth complicating the construction of a home circular in this way only in cases where a professional will use it.

Saw discs are installed between two flanges and pressed using a nut, which is wound on a thread made on the edge of the work surface of the shaft.

note! The thread should be left. During the inevitable jerk when starting the circular, the nut will be twisted in this position, and not vice versa.

Sowing places for bearings are determined taking into account the size of the latter. The most shaft has the largest diameter. If the indicator is significant, the rotation will create an additional load on the belt. Drilling will help get rid of the problem, which will facilitate the heavy part of the shaft.

The diameter of the workpiece should correspond to the size of the saw discs.

Pros of homemade circular saw

There are several rather significant technical properties, thanks to which this structure is advised to use in the following situations.

• You can put a disk with an external diameter of 350 mm on a file, which makes it possible to cut timber with a thickness of 70–85 mm. On the design, such a depth is slightly reduced, you can cut boards with a thickness of 60–75 mm. This is enough for the lion’s part of the home.made woods from wood. from a complex furniture set to ordinary toys.
• The power of the motor is at least two kilowatts, it opposes impressive loads, and a special productive forced ventilation instantly eliminates heat, which helps the systems function a long time period with optimal heat modes.
• The speed of the air shaft revolutions meets the current standards to woodworking cutting inventory. This makes it possible to achieve high.quality cut and adhere to safety regulations.
• A manual file can be attached to the countertop so that if necessary, it is promptly dismantled and applied in standard mode. At the same time, all the initial technical properties are entirely preserved.

What is necessary for the manufacture of a circular saw

Materials for creating a circular file:

• Bars made of wood 4020 mm.
• A sheet of plywood, with a thickness of at least 10 mm (the width and length is selected according to individual needs and preferences).
• Two.core cable made of copper, 0.5 mm square, approximately 1-1.5 m.
• Well.opened key located nearby.
• Electric motor that can be purchased in an online store.
• Adapter nozzle on a power unit for attaching a circular disk (can be bought on the Internet).
• Circular disk.
• Screws, screws, nuts.
• Sandpaper.
• Varnish or stain (shade is selected to your liking).

The manufacturing process consists of the following stages:

• Measurements of landing dimensions of the electric drive engine.
• Preparation of the rod of the drive of the structure and fixation racks in the workspace.
• Assembly electrical design circuit of the design.
• Assembly of the circular saw system.
• Installation of the unit on the work surface, its consolidation.
• Passing the trial of a file.
• Performing the final sawing of bars from wood and steel pruning of the pipe.

Of the positive features of such a structure, 3 keywords can be noted, this is the ease of creation, the cheap cost of materials and small dimensions.

Also, do not forget that such an apparatus poses an additional threat, so you need to work with it with particular caution. In order to prevent trauma, do not forget about safety precautions.
