Stationary circular saw from manual disk saw
Comfortable work with the machine is to install additional details that will greatly simplify work with a circular saw. This stage includes the installation of additional tools and devices.
On the scale of the working stove should be applied the symbol of the “0”. To protect yourself from chips and chips, you should install a protective screen of transparent plastic or similar material. You can facilitate wood cuts by installing additional rollers or a clamping mechanism. A stubborn plate will help prevent wood breakdown during operation.
Necessary tools for collecting circular
In the manufacture of the circular, you need to have a large number of tools and improvised materials at hand. Therefore, everything should be prepared in advance. The list of tools depends on the type of circular and the functions that it will have.
Recommended: ending with a do.it.yourself wood wood saw: we tell
You will need a standard set of tools, which includes a hammer, pliers, roulette, meter, core, screwdrivers, square, level, etc. D. You should prepare a welding machine, a drill with various nozzles, a corner grinder with cutting circles and consumables for this equipment. We must not forget about the materials and details that will become the basis when creating a circular minipila with your own hands. In some cases, you should resort to the help of specialists who will help in working with a welding machine or corner grinder.
Adjusting the crumbling knife
It is very important that the crumbling knife clearly passes one line with a blade. The adjustment of its position is carried out by placing the P-shaped goals under the mount from the side in which the knife is displaced. If P-shaped washers are not provided in the set of equipment, then they can be made independently from sheet steel.
If it is necessary to remove the crumbling knife, it is advisable to remember what goals are from different sides of its fixation. With this approach, you will not have to deal with equipment adjustment once again.
15 HABITS THAT MAY KILL YOU
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 of circular 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!)))
“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.
Preparation of a sketch, material and tool
As an example, we consider the procedure for the manufacture of 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 in which the device of the future structure will be displayed indicating the size of its main elements.
The accurate installation of the height of the table is carried out taking into account the growth of the master working on the machine (the location of the working plane at the human hips is considered comfortable).
At the preparatory stage, one should also determine the material for the manufacture of a future design, which, as a rule, is made of bars and multi.layer 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;
- Set of clamps in the amount of two pieces.
To assemble the table, a tool set from the following items is also needed:
- screwdriver and electric drill;
- Electrician or ordinary hacksaw on wood;
- a square, roulette, ruler (for current measurements);
- manual frezer
The duration and safety of work with home.made equipment depends on the types of loads, functioning modes and strength of the unit. Knowing the features of woodworking devices will make it possible to make a mechanism that will be reliable, but simple and durable.
- High disks. Without this condition, a high.quality cut of wood is impossible, but it is more important for the master to guarantee the safety of a home.made circular, so protective devices that are usually equipped with purchased models are a role model. If the future author believes that it is quite possible to do without some of them, then this opinion is erroneous, since one careless movement often leads to injuries.
- The strength of absolutely all nodes. Not only the ability to withstand large static loads is important, since the table can begin to vibrate due to multidirectional dynamic influences. They are not dangerous for the master, but affect the quality of the cut: traces of the teeth remain on the surface of lumber, difficulties arise with the maintenance of linear sizes.
- Fire safety is the main requirement when working with wood, therefore, compliance with the rules when installing all electrical appliances is a prerequisite.
What are the manufacturing options?
To make a circular with your own hands, you can use several ways. The most popular of them:
- Installation of a purchased manual circular saw on a machine made from a bar.
- The use of an indispensable corner grinder with a steel drive for wood cutting as a drive.
- The transformation into the circular of a small wooden table and engine, “leaned” from the washing machine.
- Manufacturing of a metal bed and installation of an asynchronous engine (1-1.5 kW).
All these schemes have the right to life, but in practice they have different effectiveness. If it is planned to dissolve boards that have a large thickness on the circular machine, then the only possible unit is a digital saw equipped with a powerful engine. The bed should be made of steel.
The corner grinder will be “fit” for trimming small wooden details, but for a circular saw, it is not the best option, since the time of its continuous operation is limited. The engine from the washing machine is also not the most suitable way (or rather, the most inappropriate). the equipment is uncomfortable, rather weak. Due to low power, the master will need to “invent” an increase in belt transmission, as well as a system consisting of 2 shafts. As a result of all the efforts “at the exit”, he will receive a model that has low cut quality and small performance.
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.
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.
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.
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.
Machine with a pendulum engine suspension
Those who can boast of the ability to work with metal can be advised to make a circular with a pendulum engine suspension. The main feature of the device is that the engine, shaft and cutting disk are installed in one common frame. On the one hand, it is fixed with a hinge on the bed, the second is held by a screw with the possibility of adjusting the height. By changing the length of the screw, you can adjust the height of the disc release from the countertop.
This system allows you to adjust the height of the cut, as well as use discs of different diameters. If, instead of an adjusting screw, use a probe displayed on the countertop, you can get a simple copying machine. The probe will allow you to regulate the depth of the cut according to some template. This fairly simple revision will turn a simple circular saw into a real woodworking machine. Such a device can not only cut the board into the necessary blanks, but also perform accurate cuts, make various samples.
Design elements of a wood.based sawing machine created
To make at home a stationary machine for sawing materials, first of all, you need to know what structural elements it consists of. Whether it is a do.it.yourself machine from a manual circular, corner grinder or a tool assembled from disparate elements. a set of main details is the same.
The surface of the table must be made even for a better product at the output.
The main elements of stationary circular installations are:
- Table for connecting and fixing mechanisms. If the circular is powerful and massive, it is better to use a metal table. Options are suitable made of woody stove, wood, plywood, the main thing is that the surface is smooth.
- Shaft. The most responsible detail. In the manufacture of it, a turning machine is used separately. The sizes should be calculated accurate, this will avoid beating.
- Casing. This element provides safe use of a circular saw.
- Engine. When using a corner grinder or a disc saw, it is part of the power tool.
On a note! If the design is supposed to be a team, then when creating a circular with your own hands, the engine from the washing machine will be the most successful option.
In the design of the circular, there must be mobile parts of the drives, and the power supply circuit must be mounted in the engine to stop the engine in emergency situations.
Circulars of any fixed type consist of the main parts.
The circular machine, as close as possible to factory models, requires a competent approach to assembly, so before making a stationary type circular saw, you need to think over everything to the smallest detail. In principle, the desktop mini circular saw from the stationary differs in the height of the bed, which directly depends on the nature of the work performed and dimensions of the workpieces that the device will process. One.time work can be carried out on a compact desktop saw, while the circular of a hand.free saw can be hidden without problems in the barn or pantry, and the carpenter, constantly conducting manipulations with lumber, will need a stationary homemade circular. Below there is a scheme on which all the elements and devices for a circular saw of this type are described in detail.
As can be seen from the figure, homemade circular circus circus have an understandable design, and drawings similar to the above, significantly facilitate the process of assembly. Before you make a circular, as well as mount a circular table with your own hands, consider each part of the unit separately to know all the subtleties of its work and installation.
A table for a manual circular saw with a slot in the center is sometimes redone from a conventional kitchen or collected from bars or metal profiles. Specialists strongly recommend that specialists cover the table with a sheet of galvanized metal, since without covering the basis threatens abrasion in the center from constant sip of lumber, which in turn will negatively affect the quality of the cut, and the depth of the cut will be uneven. The transverse connections that strengthen the sawing table are best made from a steel corner of 60. 80 mm with a horizontal segment in order to simplify the installation of a side limiter. The homemade table on which the circular saw will be installed on the disc, should be strong and stable, and it must also be securely fixed in a fixed position.
The toothed disk should rise above the surface of the circular table by a maximum of a third from its diameter, otherwise it will not saw the tree properly, and the process itself will become dangerous. If you need to cut a beam with a diameter, for example, 100 mm, a similar cutting parameter should not exceed 350 mm, however, the engine here will be required with a power of 1 kW. For blanks with a diameter of more than 150 mm, a mini circular made by hand is unlikely. Some factory circular machines have a crumbling knife, which is installed behind the disk at a distance of 2. 3 mm from the teeth of the saw. It excludes the jamming moment due to the closure of the parts of the cut workpiece, therefore it can be very useful in the case when a home-made circular is assembled.
Lateral emphasis with the possibility of adjustment
It is possible to put high.quality emphasis from a steel corner with a cross.section of about 80 mm, which is 3-4 cm longer than the design of the table. The flat sides of the corner are bent down so that their width is one and a half cm more than the thickness of the table. After installation, the emphasis is fixed on the homemade table of the circular in a given position using bolts. Adjustment of this element is carried out according to the template placed between it and the cutter.
The shaft installed on the circular is the most responsible node, therefore, it should be pulled out and testing with the disc with the disk exclusively a specialist on special equipment. The product from a pipe with a carelessly fixed circle is excluded immediately, because the slightest errors in the operation of this element will turn into large troubles like breakdowns of equipment, damage to the workpiece and an injury by the operator. The best solution would be to purchase a finished shaft with a seat for a cutter. It is better to give preference to ball, self.supporting bearings having a curved shape of the inner surface, otherwise the knot made by his own hand will quickly collapse and the shaft installed on a home.made circular will become unusable.
In our case, the ideal option would be a cuneiform transmission, but it is better to abandon a gear hard mechanism, since such a home.made does not guarantee security. If a nail suddenly comes across in the lumber, the engine rotor provoke the destruction of the disk, which can lead to injuries. If the internal diameter of the belt pullers is small, then slippage will be provided, and the stretched belt will serve as a kind of damper. The gear ratio is usually selected based on the engine speed, be sure to consider the permitted number of speed revolutions. The smaller the diameter of the saw circle, the greater the frequency of its rotation, and the cleaner the converted unit will be cleaned.
Among homemade devices, the circular assembled from the engine from the washing machine is most popular.This choice is explained by the fact that the scheme of her work is best suited for such goals. Unlike collector units, which the power tool is usually supplied with, the engine from the washing machine operates at less high speeds, which means that it shows a longer operation, has increased efficiency and is not so subject to all kinds of clogs. You can also use a three.phase engine, but then additional expenses for the purchase of a starting and working capacitor will be required, so it is more economical to cost the device from the washing machine. Here, in general, and all the wisdom.
Selection of materials and details
When creating a home.made circular saw, it is necessary to comply with the optimal balance between its functionality, safety during operation and the cost of manufacturing. To achieve this, you should choose materials and details with the desired characteristics. To reduce costs, it is necessary to build from old or unused equipment, which is available.
Materials for the manufacture of bed with the table
For the manufacture of a bed (frame), you can use a channel or metal corners (enough from 25 × 25 mm to 50 × 50 mm). If these materials are not available, then the most economical option is to purchase them at the scrap metal intake. Water or profile pipes made of metal will go to the legs of the machine.
Advice! Elements of the frame must be connected to each other using electric welding, because bolted connections are spinning under the influence of vibrations.
When collecting the bed, it is also required to weld the structures in the corners to weld the spacers. To facilitate the movement of the machine, you can equip it with strong wheels (with a metal rim) equipped with fixers. It should be borne in mind that the more massive the created unit, the more it should be more stable in order to avoid injuries.
The main requirements for the table for the circular: resistance to mechanical influences (vibrational, shock), the ability to withstand the harvesting weighing more than 50 kg and smoothness of the surface without deflections. These properties are characterized by sheets of the following materials:
If you use a moisture.resistant plywood, then it should first bend it with tin covered with zinc. It is not recommended to use wood-brown stove or OSP due to the instability of these sheet materials to vibrational influences.
You Can MELT METAL In Your HAND!. Liquid Metal Science Experiments
Important! The strength of the table is of great practical significance. When it cracked or distorted due to deflection, the disk can jam. This can lead not only to damage to the workpiece, but also to the injury.
To carry out various works (for example, bloating logs onto the boards), you need to equip the table with a lateral emphasis. It performs the same function as the tire for a manual type circular saw: provides even sawing of lumber. In this case, its use allows you to get blanks of different sizes.
The guiding emphasis should be strictly parallel disk to avoid jamming the last. It can be made from a wooden bar or metal corner. In the first case, only solid wood should be used. To be able to adjust the working gap, the emphasis must be removable. It can be fixed using clamps or in special grooves (bolts) made parallel to each other on the working surface of the countertop.
The choice of engine and launch equipment
As a drive for the version of a home.made circular machine, it is easiest to use a single.phase electric motor. Its power is required to be selected taking into account the upcoming load. Indirectly, you can navigate the diameter of the installed disk:
- If it is 350 mm, then for the normal operation of the unit you need an electric motor with a capacity of 1000 W;
- For a disc with a diameter of 170 mm, a 500 W engine is enough.
In the latter case, you can make a drive mechanism from the engine from the washing machine-automatic machine. He is able to work for a long time at an average load level. For discs with a diameter of 350 mm, an electric motor from an industrial ventilation installation is suitable. It should be fixed rigidly to ensure the normal gearing of belt transmission. For this reason, it will not be possible to reduce the level of vibration by installing the motor on shock absorbers: it will constantly fluctuate.
You can also equip home.made equipment with a three.phase electric motor (380 V) of suitable power. To run it from a network with a voltage of 220 V, it will be necessary to additionally install a working (phase.drive) and launch capacitors in an electric circuit. It should also be borne in mind that the engine power will be less than the nominal value indicated on its plate or in the passport.
The starting equipment should be selected based on the power of the motor, on which the maximum current strength in the circuit will depend. A good option is the use of the start button together with thermal protection. this will protect the electric motor from blocking the windings if the current increases when the disk is jammed. It is better to install protection in a separate electric shield attached to the side panel of the machine from the convenient side.
All connections need to be isolated so that the wires do not closed onto the bed of a home.made circular electric saw. The inclusion and disable buttons should be pressed without any effort. Due to the frequent storage of equipment on the street, it is necessary to protect the electric part well from getting wet. The simplest thing is to cover the installation with an oilcloth or a material that does not pass water that does not pass water.
Transfer, shaft and disk
To transmit rotation from electric motor to the disk, the best option is to use a wedge.shaped belt together with pulleys from the car engine. It is not recommended to use gears for security reasons. This is due to the fact that if the disk is jammed, then the belt will simply slip, and the gear gear can cause failure of the entire drive node due to its rigidity.
Advice! If you use pulleys of different diameters, then it will be possible to change the speed of the disk and install various types on the machine. This is relevant in the absence of a regulator of the speed of the electric motor.
The manufacture of a shaft is best entrusted to a specialist by ordering it from a professional turner. Especially when it is planned to make a circular electric saw more functional, equipping it, for example, a shirt. But the easiest option is to buy a finished part of factory production. Its sample is presented in the photo below.
Assembly algorithm for a home.made circular saw
The assembly of the woodworking machine according to the previously given drawing is performed in the following sequence:
- A rectangular frame is made from the corners;
- Four legs are welded to it in the corners of the desired height;
- At an altitude of about 200 mm from their lower edge, a strapping of corners is made;
- The shaft is mounted on the upper frame;
- The driven pulley is fixed on one side, and on the other. a disk;
- make and attach a table with a lifting mechanism to the bed;
- A platform of corners or sheet metal under the electric motor is made on the lower frame;
- A leading pulley is fixed on the motor shaft;
- put on the belt on the pulleys;
- On the side panel of the unit, mount the buttons of turning on and disconnecting and electrical panels;
- Using wires of the right section, the elements of the electrical circuit of the equipment (engine, buttons, protection) are connected;
- Supplose power to the machine from a stationary network.
The final step is to check the performance of the assembled equipment. First you should make sure of the free rotation of all mobile details: for this it is enough just to twist the leading pulley with your hand. Then you can start the unit in test mode. If severe vibration is found, you will need to check the reliability of bolt compounds and disk fixing.
You can make a circular saw with a table consisting of two halves or whole. In the latter case, it will need to cut a rectangular slot under the disk. The design of the machine with a table consisting of two halves is shown in the video further. This video also demonstrates the device of the lifting mechanism for these parts.
Important! To prevent the possibility of jamming the saw due to the connection of fragments of the sawing workpiece, it is recommended to install a crumbling knife. It should be placed at a distance of about 3 mm behind the disk.
Stanin and table
The creation of an easel circular using manual power tools begins with the construction of a countertop or a box.shaped case, where a manual circular saw will be located from below, and part of the sawing disk will be located above the surface.
On the Internet you can find a lot of reviews in which the table for the circular with your own hands with drawings is presented, as well as the manufacturing technology in detail.
Usually, if you work with small details, for comfortable work is quite a length of 1.5 m and a width of 0.7 m. The bed can be boiled from a metal corner with a shelf up to 30 mm. In the corners of the frame should be strengthened with welded UKSINES, thanks to which maximum reliability will be ensured.
It is best to make a bushings from the stove a wood-cutting plate, a wood-fiber slab. Fat plywood is often also used. If there are sheets of thin plywood in stock, you can connect two sheets. It is necessary to symmetrically fix the countertop on the basis of avoiding the risk of overturning.
In the middle of the countertops, a rectangular window is made, which is then closed by an insert of duralumin or plexiglass with a slot for a disk. Such an insert allows you to ensure smooth movement of the processed board or sheet along the ruler.
DIY circular: Safety of use
If we take into account how much the circular costs (from 16,000-the most modest model), and compare the price with the cost of independent manufacture (this is 60-90% less), then the difference is significant. But no savings will be justified when the safety of work is not ensured.
Before starting work on the circular, it is necessary to wear glasses and gloves.
In order to avoid traumatic situations, you should adhere to the following recommendations:
- Do not use wood with metal inclusions (nails, corners, bolts, etc. D.);
- Two people should be sawing boards with a size of more than 200 cm;
- Working on the circular, you cannot make sudden movements;
- Before starting work, it is necessary to put on glasses and gloves;
- Wood waste from the surface of the circular should be removed, as they can provoke a short circuit.
It is strictly forbidden to work on a home.made circular machine:
- if the guide device is not made;
- there is no casing;
- There are no fuses holding fingers;
- crumbling knife above the saw disk.
To avoid traumatic situations when working with circular, you should adhere to safety precautions. A solid tool makes it possible to enjoy work. And the result pleases with a high level of quality. DIY tools will make the desired parameters and the necessary operational characteristics. It is impossible to be limited to superficial knowledge in any type of activity, especially the technical direction. It is worth taking on an independent assembly of the circular only after careful theoretical preparation and a complete idea of the practical part of the process.

The main technical characteristics and criteria for choosing circular saws
An important feature of the selection of equipment is the number of teeth. The purpose of the disk depends on this characteristic.
Directly from the number of teeth, a specific series of tasks is formed that the tool will cope with:
- A small number of teeth will be needed for rough cutting of wood plates with different density levels. In this case, the carved surface will be inaccurate, and its quality will be low
- The average number of teeth is suitable for a wider SPECTRA performed by a specialist work. This is a longitudinal and transverse cut of wood blanks, rough processing of metal blanks.
- A significant number of teeth are used as often as possible in work. These are transverse and longitudinal cuts in wood with high density, cuts, plastic and laminate, work with metal blanks.
This parameter has an important role when buying equipment. The higher the value of the power parameter, the better the saw will perform its work. It is important in the formation of specific tasks. Materials with a dense texture need equipment with maximum power equipment.
Circular saws are produced in three types with power level:
The weight of the tool depends on this indicator. It should be taken into account. It is incredibly difficult to work with a weighty unit.
It’s important to know! If the power of the device is less than 1 kW, it is not recommended to be taken to work with large blanks, since there is a chance of squeezing the blade in the wood.
The speed of rotation of the saw disk and its diameter
This indicator directly affects the performance of the tool, its ability to interact with materials with a dense and solid texture. The accuracy and evenness of the cut depends on the frequency of rotation.
Equipment with a high speed of rotation noticeably simplifies the workflow. The saw will pass the material (even dense) much faster, there will be no burrs and chips on the cut. However, if the speed of rotation is too large, the disc canvas is rapidly heated. As a result. traces of a burn can remain on the cut. Working with plastic, the edges will be melted.
Choosing a tool for rotation, equipment with an adjustable mechanism will be preferred. This will allow the master to independently adjust the parameter for the type of raw materials.
When choosing a saw disk, technical data are important: external and internal diameter. The first-affects the depth of the cut, its parameters fluctuate within 65-500 mm. The designated values are constant. Disk dimensions are limited by equipment design. Second-should be the value of the diameter of the shaft of the circular saw (10-55 mm)
Direct depth of the cut and at a right angle of 90 °
This parameter directly depends on the dimensions of the disk used, and if they are small in size, then it will be impossible to carry out accurate and high.quality cuts with large dimensions.
It must be borne in mind that saws are useful for home use, which perform a depth of work 40-50 mm. If the indicator is higher, then such an instrument is suitable for activities where the saw depth directly forms the effectiveness and professional quality.
The main part of the saw is cut not only by the straight line, but also at an angle of 45 degrees. Recently they began to produce tools that are cut at an angle of 60s °.
Experts recommend paying attention to the parameter of the maximum depth of the saw at an angle of 90 degrees. This is possible with a sequential movement of the saw perpendicular to its surface. If the workpiece has a thickness of up to 40 mm, then you should choose a tool with a similar depth.
Types of saw discs
The saw disk is made in several variations depending on the purpose and the type of material used. They have a similar design, and differ in separate technical and operational moments.
Depending on the structural characteristics, they are classified in two directions:
- Monolithic disk. It is made of steel with high M 2, is considered unpretentious in care and maintenance. It is used mainly for work with low density materials (soft wood, individual types of concrete and cement). The main minus is quickly stupid.
- Cool disc. Made of instrumental steel with attacks from tungsten, cobalt and artificial diamond. Characterized by high strength, stability. The carbide disk is universal, applicable to work with materials of any density. The teeth are sharpened more slowly, the cut is smoother, more accurate.
Additional functions of circular saws
Circular saws are able to cope with complex tasks. To make the work extremely effective and comfortable, the models are equipped with additionally special capabilities. Their task is to make the work process as accurately as possible and facilitated.
