How to make end work. Homemade practical miter saw. Features of models with double primer

A miter saw is a device that every builder needs to take "into service". However, it is no secret that high-quality professional toolpresented on the construction market is quite expensive. That is why those who want to save material resources, as well as show their skills, should try to make a miter saw with their own hands. The starting material for this will be a circular saw.

Varieties of miter saws

There are several types of miter saws (popularly also called "miter saws"). Let's get acquainted with these varieties.

Pendulum

The basic part of such a saw is the bed. A table is attached to the bed, which must have a swivel mechanism equipped with a ruler. It is this mechanism that allows the cutting process to be carried out at a certain angle, adjusting it to the specific individual needs of each user. Moreover, this angle can be changed by moving the desktop directly relative to the bed.

As for the saw itself, it is fixed in this device by means of a lever, and also spring-loaded by means of a hinge. Thanks to the pendulum, which gave the name to this type of miter saw, the saw moves up or down.

Combined

When using a combined saw, the cutting angle can be changed in 2 directions. The device, like the previous version, contains an additional hinge. In order to change the cutting angle, it must be adjusted and retracted to the side opposite to the place where the drive is mounted.

With a broach

This device is considered the most versatile, since the saw can be displaced not only around the axis, but also along the cut in a straight line.

How to make a circular trimming?

If you do not have the ability or desire to purchase a ready-made miter saw, then such a device can be made yourself. However, it will not work to do it completely from scratch. The initial design should be a hand-held circular saw and drawings.

So, in order to make a trimming with your own hands at home, you need to make a box that will serve as a base... As a raw material for the manufacture of the box, you can use chipboard (chipboard).

In the process of whipping and assembling the box, experts recommend using confirmations consisting of 1 element - they are inherently ordinary ties for connecting wooden parts... The final box for the base for trimming must have the shape of the letter "P".

When making a box, it is important to ensure that it does not move.It is often attached to the work table with special clamps (the tool used to fix it). Next, on top of the shelf, you need to screw the manufactured base under the saw.

Important: When attaching the base, you must maintain a 90 degree angle, otherwise you will not be able to align the blade sole.

On both sides, using self-tapping screws, it is necessary to fix small pieces of chipboard. Thanks to this manipulation, you will adjust the position of the sole of the instrument. The next step in transforming the circular is to fix it. Moreover, this should be done using all the same clamps, and you can also use wing clamps.

Next, you should proceed to the installation of the so-called table.It should be fixed near the base of the table. However, keep in mind that in the process of carrying out this activity, you reduce the cut in depth by 1.5 centimeters, so try to put the profile as close as possible in relation to the saw element.

After carrying out the above described manipulations, you can proceed to the test cut - you should get a cutting line based on the stop. If so, then you did everything right.

As you can see, from the circular hand saw it is quite possible to make a miter tool.The main thing in this is to strictly follow the instructions and recommendations, as well as make a little effort and be patient.

Advantages and disadvantages of a homemade device

Like any other device, a homemade miter saw derived from a hand-held circular saw has its own characteristics and features. Some of them are positive, while others are negative. One way or another, it is necessary to take into account both those and other signs.

Pros.

• The first and most important benefit of a DIY miter saw is the significant savings financial resources... So, buying a ready-made tool will cost you quite a lot (the average cost of a device is 10,000 rubles), and making a tool with your own hands from a material point of view is available to almost everyone.

• Another advantage of a hand-made device is the fact that all parameters of the saw (for example, cutting depth, speed, power, length and width of the base) are selected individually. Thus, this device will be more efficient for personalized work than a purchased unit.

• In addition, having made the saw yourself, you will be well acquainted with all the constituent parts, which, in turn, means that in case of any breakdowns and malfunctions, you can easily repair the tool.

Minuses.

• Often as raw materials to make a miter saw with their own hands, use the available tools on the farm. It should be noted that such materials are not always of high quality. That is why the life and quality of the homemade device can be very short and low.

• In order to make a unit, you must have at least minimal technical knowledge and skills. A beginner will not be able to cope with a task of this kind.

• Homemade trimming is not suitable for jobs that require high power saws. If you need just such a unit, then for its manufacture you will need professional parts, extensive knowledge and a fairly large amount of time. Thus, it is easier to buy a ready-made device.

• The miter cut, which you make yourself from a circular saw, will not have the proper safety indicators and may turn out to be traumatic during operation.

For more on how to make a miter saw from a circular saw, see the video below.

Miter saw - the same circular saw based on a conventional circular saw. It allows you to cut with great precision under required angle almost all materials - from plastic to metal. There is such a tool from the manufacturer, that is, ready-made, not cheap, and assembling it yourself is not so difficult. Therefore, if you have an urgent need for a miter saw and your arms are growing out of the right place, further information will be very helpful.

Interesting!Having assembled the tool with his own hands, any master can easily find the cause of the breakdown and eliminate it, which will additionally save money.

A miter saw consists of several essential elements

• the saw blade itself;
• a handle to hold and guide the tool;
• engine;
• footrest with start button.

Important!Regardless of the manufacturer, such a tool is always equipped with a durable disc, which makes it so versatile in use. If we set out to assemble the trimming with our own hands, then we buy the disc ourselves, and therefore do not forget that in this matter it is better not to save money, but to choose the most durable disc for such needs. A native circular saw blade is fine.

Let's get to the heart of the matter: you have a circular in stock, and you are assembling a homemade miter saw. The first three points are already present in the circular itself, and the fourth may not be needed if you skillfully assemble a guide bar for the saw.

How to make a miter saw

This will require

• plywood sheet;
• aluminum corners;
• self-tapping screws.

Let's start assembling

1. Cut out a rectangular sheet of plywood and make a long cut on it, along which your trimming will ride;
2. From above we fasten two guides, for example, from an aluminum corner, to the width of the working plane of the circular itself;
3. From the bottom to the plywood sheet, you need to screw two supports with a height equal to the cutting depth of your saw (5.3 cm).

As a result, we get a guide along which the circular will walk. Depending on how we fix it on the table with such simple mechanism, we can make an accurate cut at any angle. The simplest design is ready.

What if we want our miter saw to be more functional at work and look like a factory miter saw? In this case, you will have to be more smart.

1. First, you need to make a bracket and a stand on which the circular will be fixed. Chipboard (27 mm) is an excellent raw material for such a mechanism. Using self-tapping screws and aluminum corners you will end up with a very decent top of the trim. And the springs fixed from above can make working on such a saw more convenient;
2. Secondly, you need to fix the tripod itself on a movable swivel footboard, make pendulum saw, thanks to which we will eventually be able to change the facing angle.

Caution! What material you choose for the stand and tripod, how securely you attach them to the footrest, will depend not only on the quality of work and functionality of the trimming, but also your personal safety. No wonder they say that « if the carpenter is experienced, then he must be without a finger » ... Secure the circular as securely as possible! Safety is above all!

As for the trimming itself, everything is said about the assembly. However, if we decided to make a saw that looks like a factory saw, then it will be difficult to do without a table.

How to make a do-it-yourself miter saw table

A 19mm MDF board can be a good material for a table.

1. Measure the depth and width of the entire structure (miter saw);
2. Now measure the width and depth of the workbench on which the table and the trimming itself will stand;
3. As a result, the lower part of the MDF-board table should be equal to the width and depth of the workbench, and the upper part should consist of two parts and in total be shorter in length by the width of the miter saw;
4. The height of the table should be equal to the cutting depth;
5. Inside the table (between the top and bottom plates) at a distance of 50 cm, it is important to make rigid partitions from the same MDF board. This is necessary so that the table does not bend when pressed.

Now everything is for sure. The miter saw from a regular circular saw is ready.

Interesting!A miter saw is a rather dangerous piece of equipment in itself, but if you also assembled it with my own hands, the danger of such a mechanism can increase significantly! On the other hand, by assembling all the parts yourself and taking care of all kinds of protective boxes and covers, you can reduce the risk to a minimum. In this case, the rule applies: « Your safety – only in your hands » .

One of the most important tools used on the construction site and for some renovation works, Is a miter saw that can cut workpieces and material at any angle and any inclination. This possibility is provided by the existing turntable, the movable working part of the device and, accordingly, by the disk itself above the bed. Using it, you can cut wood, plastic, hardboard, OSB, laminate and other materials of not increased strength.

To choose the right tool, you should consult with a specialist who understands not only the order and way of performing work, but also miter saws with a broach.

In principle, the construction of the saw is simple and comprises motor on the gearbox, saw blade, platform and handle with a convenient location of the start button. The engine uses a collector motor, which has a greater number of revolutions, but requires periodic replacement of brushes. And asynchronous, which is quieter in operation, but at the same time more durable in use.

The transmission of torque for the disc is provided by a gear or belt transmission through a gearbox. To avoid slipping of the product, use the first gear. When shifting to second gear, vibration is reduced and disc rotation is stabilized, which is more suitable for a long service life. The most reliable is direct transmission, which is used in some copies, but they are disadvantageously low rpm.

To turn a regular saw into an end machine, a broaching mechanism is built into it. With this option, the module itself is located in the structure on parallel rails. This design approach makes it possible to cut large-sized products.

For the bed, magnesium or aluminum is used, and the base itself is a rounded part, set at the desired angle and stop. The kit also includes a cover to protect body parts from injury.

The basis and very important element of the design is the table. With the right tools and some knowledge, you can set up a miter saw table with your own hands. It has two sides that are attached to the rack. The neck fits exclusively on feed saws.

To measure the position when rotating the table, angular scales are located on the base. The rotation angle can be between 0 and 45 degrees. A special groove on the latches securely fixes the rotary part and provides the most accurate fixation.

There are some tilt stand designs. But such a design requires more complexity and more nodes, which will lead to a greater likelihood of breakage. Yes and the need for tilting is not so great and only occurs when trimming certain types of skirting boards and moldings.

Built-in clamps provide secure fixation of workpieces on the table. And when using sufficiently long workpieces, retractable stands and stops are used, which are installed in the bed and expand the dimensions.

Facing settings

To block the mechanism for replacing the disc and, accordingly, stop the engine, the device is equipped with a soft start. For safety reasons, the models are equipped with protection against electric breakdown through the case.

To adjust the cutting of metal products, electronic units are built in, which allow you to adjust the process depending on the properties of the material. Electronic components are also installed as a precautionary measure to ensure safety and prevent damage from overheating, jamming, braking when the tangential load is exceeded. And it also allows you to more accurately cut the workpiece. Although usually saw models come without the listed units.

In order to be able to calculate the number of manufactured parts for a certain period in an exact quantity, newer models are released that have the option of setting the exact number of revolutions. Another useful but expensive function in the device is laser guidance system for precision cutting. This system can operate both from the mains and from batteries. Its essence is simple and very suitable for beginners, as they see the line of the future cut, indicated by the laser beam. And beginners, if they have drawings, can make a miter saw with a broach with their own hands.

In the process of this production, a large mass of sawdust and small parts from blanks remains. Some models have a built-in vacuum cleaner, which later saves cleaning time and saves workplace always in a relatively clean state.

The quality of the cut is affected by the disc with which it will be made. AND saw blades can be distinguished by the following criteria:

• configuration and geometry of teeth;
• outer diameter;
• landing hole.

The inner diameter in conventional configurations is 3 cm, and the outer diameter can be from 21 to 30 cm. This information is indicated on the side of the disc without fail. Great importance the outer diameter indicates that the load on each of the teeth during operation will be less. And this will lead to a longer drive life. Also on the disc is indicated its marking, the permissible maximum rotation speed and how compatible it is and with which tool.

Disc teeth and their configuration

The quality of the cut depends on the quality of the sharpened teeth, their size, the material from which they are made, and the shape configuration. For a high-quality cut, which is used when working with laminate or varnished treated wood, be sure to use fine-toothed discs. The running time of smaller teeth differs in duration, but better in quality. And for working with soft woods and plywood, a disc with large teeth, even located at a greater distance from each other.

There are the following types of teeth for circular discs:

• trapezoidal;
• with carbide taps;
• with ATV solders.

When choosing a tool, it is very important to pay attention to the model brand. It is important to consider in what environment you will work, with what materials, what time. Although instruments from different brands have typical characteristics in terms of categories, they can still differ significantly from each other. Each manufacturer uses its own approaches, materials, problem solving concepts. Also, do not miss the moment that the manufacturer can still try to save on something, but force something, and it is no secret that any thing can have weak points.

Before considering the rating of these aggregates, you need to pay attention to the manufacturers of the most used and reliable brands and be able to choose the best broach miter saw, which is:

• Makita.
• BOSH.
• Devalt.
• Hyundai.
• Metabo.

Saws of these brands do not raise questions about quality from the user. The only remark from the people who used the devices was about the disc backlash when the guide rails out. But this phenomenon is typical and acceptable.

Miter saws Makita

In the ranking of the safest saws to use and having a high-quality assembly, the Makita brand can be noted. In them, the traction allows you to choose the cutting width. Allows you to make combined cuts, inclined and oblique. Of the professional versions of this brand, Makita LS-1216 can be distinguished. Thanks to double guides, this is the most the best choice for work on plastic and wood, makes the most accurate cuts and the widest, up to 107 mm and 363 mm in width. These dimensions are the maximum for instruments of this class. The cost of the unit is around 45 thousand rubles.

BOSH

This company has long secured its place in the world market as a manufacturer of quality and reliable items. Moreover, the gradation of the target potential client can start from a simple amateur and reach professional companies that work with tools of this brand every day with full and maximum load. Their saws are equipped with a specialized circle, a self-adjusting angle of the bed. For durability, aluminum and magnesium alloys are used in the design of this brand.

The best budget option for a beginner craftsman and just an amateur is Bosh PCM 7. This model can be easily fixed on the bed. It is equipped with a laser for an accurate cut, a small disc diameter, a 1.1 kW motor. And you can buy it for 11 thousand rubles.

Professionals can opt for the Bosh GCM 8 SJL Professional saw. Its design has a very large number of settings, which allows you to perform work of any complexity without damaging the surface or deforming the end of the cut. But she does not have the ability to adjust the number of revolutions. But there is a dust collection system, which will suit professionals. And the cost of such a unit will already be 32 thousand rubles.

Saws from Metabo

A unique property of the Metabo side saws is the ability to tilt and turn the blade using a special adjuster. Cutting accuracy is ensured by the projection system, which gives a shadow on the workpiece from the disc.

The most used model is the Metabo KGS 305. The set includes a 2 kW motor, quite convenient control of the adjusting levers. And the tilt angle reaches 47 degrees and rotates 60 degrees. The good thing about the tool is that it can cut efficiently and accurately, and even work with a 100 x 100 mm bar. This purchase will cost the buyer 26 thousand rubles.

Saws from DeWalt

A distinctive feature of this device is the presence of a unique XPC system that allows you to cut material of any strength very accurately.

Of this brand, one can distinguish DeWalt DWS 780, which has a fairly rigid and reliable structure base, which makes it possible to work on it as safely as possible. The device has a 1.65 kW engine and a speed control system. For such a copy, you will have to pay 53 thousand rubles.

Do not forget that when you buy a tool, you will only pay extra for the brand. But still, when choosing, it is best to be guided by opinion experienced craftsmentested different specimens in working conditions.

The miter saw is created by hand on the basis of the existing equipment - a hand-held circular saw, an angle grinder (grinder). And when mounting discs of a specific type homemade device can be used to cut a profile on a metal-plastic base, pipes, which will increase the area of \u200b\u200bits use.

Varieties

Cross-sections are divided into the following types:

• pendulum;
• combined;
• with a broach.

The base of the pendulum device is the frame. A table is also attached to it, which is based on a rotation mechanism with a ruler. This mechanism solves the problem of setting the cutting angle with its adjustment. The cutting angle can be adjusted by moving the table in relation to the base surface. The saw component is held in place by a handle and is spring loaded with a hinge. The pendulum moves the saw vertically.

In the combined modification, it is possible to change the cutting angle in two directions. The structure is the same as that of the pendulum facing, only one more hinge is added. As for changing the cutting angle in a horizontal surface, it can be changed in the horizontal direction, which is also opposite to the installed drive.

Crosscutting with a broach allows you to translate the cutting component both along the circumference of the pivot axis and directly along the length of the cut. This is obtained due to the existing guides.

Tool creation

It is possible to make a miter saw with your own hands, taking the available equipment as a basis.

From a hand-held circular saw

The structure is common and acceptable for home construction. The body of the trimming unit is made of wood or iron. A base is constructed from plywood sheets (chipboard), on which a vertical rack is mounted, having previously cut holes in it to fix the facing. A pendulum-type device is made from a board and is attached to the base by means of a long bolt.

Having prepared a steel rod or corner, it is attached to the top of the pendulum so that the end sticks out.Then a spring is taken, one end of it is fixed to the rear shelf of the corner, and the other - to the vertical rack. The tension is selected empirically, but it should be enough to easily hold the circular saw in the hanging position.

Having removed the handle from the equipment, it is fixed on the pendulum in a previously prepared hole. The wires are placed in the slots prepared for this, and the power supply is connected. A small slot is made in the table top, and side stops are fixed to it at an angle of 90 °. If they are made rotatable, then it will be possible to cut the blanks at a specific degree. The unit is assembled, it remains to test it in operation. Using drawings, you can make anything, even a very complicated apparatus.

From the grinder

Miter saws are capable of cutting wood, iron, plastics and other materials.

The most famous facing is based on the use of an angle grinder.

If you can do everything correctly, your device with a broach will have the following options:

• disk rotation speed - 4500 rpm;
• cutting distance - about 350 millimeters.

If necessary, trimming is dismantled from the unit and is practiced as usual hand tool... A big plus is that the homemade device is versatile and can be easily disassembled.

Let's consider how the manufacturing procedure takes place.

1. Place the swivel mechanism of the angle grinder on the pivot of the implement wheel. Its fastening is made by means of a ball bearing. The recommended size is 150 millimeters, but larger ones will also work.
2. Ears are welded on the outer side of the bearing. They are designed to secure the base of the unit. Install with M6 screws.
3. The holder should be covered with a protective cover so that chips do not fly on you during operation.
4. The broaching problem finds a solution simply. To create it, take shock absorbers from a truck. Even if they are not in working order, this is not a problem. Remove any lubricant from the shock absorbers, drill holes for ventilation and cover with a mesh to prevent chips and dust from entering the cavity.
5. Install the soft start module. Thanks to him, you will not experience sudden jerks during the start of the trimming.
6. The final stage is the installation of the saw blade guard.

Depending on the disc supplied, the unit can be used for metal or wood, for trimming pipes. But be aware that the power of the unit may not be enough to cut the ends of the pipes. Decide on the technical parameters of your angle grinder to find out if the machine is capable of cutting pipes, or if it is only suitable for working with wood.

This design has two important drawbacks.

1. To adjust the precision of the cut, wood residues are used first. Then the traction is fixed, and you can get to work.
2. The unit makes a lot of noise when cutting pipes and working on iron.

Manufacturing of a complex unit

There is an option with a more complex and heavier design. She will definitely cope with facing metal pipes... At the same time, a self-made device does not require the use of a circular as an element of the unit. But for specific moments of work, it is better to keep the circular at hand.

Based on the selected components, you have the opportunity to make a high-power unit. To create it you will need:

• an electric motor with a resource of about 900 W, and if you need constant cutting of pipes, you can take a more powerful electric motor;
• sheet iron;
• metal corners;
• channel;
• hinge groups;
• angle grinder;
• welding machine;
• file;
• powerful spring.

When everything you need is prepared, you can start assembling the end machine.

1. The bed can be made using customizable supports, metal corners and bed racks.
2. A sheet of strong iron is used as a working surface. It is necessary to make holes in it and file them with a file.
3. For the manufacture of the pendulum rack, we use a channel and a welding machine. The structure is placed on an iron sheet. Approximate stand height 80 cm.
4. The base for the electric motor is made of iron sheet as a stationary plate. The bed is necessarily mounted on hinges.
5. A powerful spring will serve as a stabilizer for the electric motor of the miter saw. If you find one, then you can refuse from the swingarm and belts.
6. The lifting bolt can be used to tension and adjust the belts. The pendulum can be made of steel to make the structure strong and reliable.
7. The cutting tool will be a disc of the required diameter. For household tasks, as a rule, a saw blade with a diameter of 400-420 millimeters is sufficient.

Advantages and disadvantages

Homemade miter saws have both positive and negative properties.

To the benefits homemade units a number of characteristics can be attributed.

1. The creation of a trimming machine will require an order of magnitude less money to be invested than the purchase of industrial equipment for trimming wood, pipes, plastic and other things. Roughly, experts invest from 500 to 1000 rubles for re-equipment of an angle grinder.
2. You have the opportunity to independently select the performance characteristics for the future end machine. Such parameters include the dimensions of the working surface, the power of the electric motor, the diameter of the discs, the cutting depth, and more.
3. The manufactured devices have a simple design. For the reason that you yourself assembled and disassembled the device, there will be no difficulties with finding breakdowns.

The miter tool is lightweight and compact. Effective as stationary machine... Fixed fixation of the workpiece allows for high-quality cuts. Some cross-cut patterns include devices for optimizing corner cutting, a speed controller that allows you to select a mode depending on the type of material, the required processing quality. The trimming unit can be made independently.

Most often, the saw is assembled from a grinder.

For a good job:

• The original disc tool must run at least 4500 rpm.
• Cutting length - at least 350 mm.

If necessary, the grinder installed on the table for the miter saw can be dismantled and used for its intended purpose.

Build process

First, a table is made on which the cutting unit will be installed. The frame is constructed from a metal corner using the welding method. From above, the stand is covered with a thick sheet of metal with a longitudinal hole. The edges of the bed are filed.

The saw from the grinder is mounted on the axle. This allows you to trim workpieces at an angle... The swivel mechanism is fixed by installing it on a bearing with a diameter of 150 mm. The structure is fixed with a mechanism connected to the axle. The axle is lubricated from time to time to exclude the occurrence of a squeak, excessive friction.

For facing blanks at a certain angle at the time of assembly, the saw is equipped with ears welded on the outside of the machine at a short distance from each other. If this is not done, there will be backlash and the accuracy of the cut will suffer.

During operation, it is necessary to ensure that no sawdust gets into the bearing: this can lead to rapid wear of the mechanism, the rotation of the disc will be difficult. Use a lubricant for added protection.

The most effective for wood processing is trimming with a broach, a shock absorber. It is better to choose samples installed on trucks: they are more resistant to aggressive mechanical stress, hardy. The part is freed from oil, provided with technological holes that will serve ventilation ducts... As protection from sawdust, wood dust, the holes are tightened with a mesh with a fine mesh section.

Another useful option for the miter circular saw is the module smooth start... Thanks to him, the machine does not make sharp jerks when starting up. The principle of operation of the part is to reduce the speed at the start. As a result cutting disc trimming is gaining momentum gradually. It is difficult to assemble the stabilization module on your own. It is recommended to remove the part from another device or buy.

At the final stage, a shield is made to protect the miter saw from getting into working area third-party cutter.

If you have a conventional circular saw, you can make a movable carriage. It is easy to install, assembled from a plywood sheet, guide bars and fasteners: bolts, screws.

Important points

The machine makes a lot of noise during operation.

In order for the tool to accurately perform the intended cut when processing the ends of the workpiece, you need to try to position the grinder as accurately as possible relative to the wooden parts. You can adjust the placement of the cutting element using the bars, while the rod must be fixed with a bolt.

The miter saw can be installed in the garage, workshop, basement, and other places. The main thing is that the working structure is firmly connected to the base.

The saw blade must be carefully selected. It must correspond to the specifics of the work, the characteristics of the material.
