Accessories for the grinder: do it yourself. Attachment for cutting sheet metal with a grinder Attachment for a grinder for cutting metal drawing

An angle grinder - a grinder - is indispensable either in the garage or in a private courtyard. The unit allows you to cut a metal profile, clean up a welded seam or remove rust from the surface of workpieces and parts, has a low price and incredible ease of use. The grinder also has disadvantages, one of which is the unstable cut quality and the danger of skewing the cutting disc during use. You can eliminate the annoying shortcomings by making a special bed with your own hands, which will turn a hand tool into a real cutting machine. This will increase the speed of work and achieve accuracy that can only be obtained with industrial equipment.

Scope of cutting machines

Cutting disc machines are widely used in metalworking, mechanical engineering, woodworking and furniture industries. The units have found their application in the household as well: they are used as a handy tool for performing various works in the workshop and garage. The cut-off machine is convenient to use for solving a number of tasks:

The advantages of disk cutting machines include convenience and ease of use, high cutting speed and accuracy, the ability to replace the cutting blade in a matter of minutes.

Due to their relatively low cost, universal units have quick self-sufficiency, so they are beneficial to use in small industries and in small workshops.

In the household, the cutting machine is used irregularly, so buying a factory-made tool is irrational. Better to make a special bed for an angle grinder. This will increase the versatility of the grinder, turning it into a small-sized cutting machine.

Types of adaptation, their advantages and disadvantages

There are two types of cutting machine designs, differing in the location of the grinder, which can be made at home.

The first installation is a frame with an angle grinder rigidly fixed under it. On the working surface, only the cutting disc is visible, which freely passes into the slot of the table. Cutting a metal profile or sheet in this case is completely identical to cutting wood blanks with a circular saw. Despite the very simple design, such a scheme is not very popular. Those who made such a device note the inconvenience in use due to the need to move the workpiece. This greatly reduces the accuracy of the work and makes the process unsafe. The only advantage of a machine with a bottom angle grinder is the ability to quickly cut thin metal sheets.

The cut-off machine with the bottom position of the grinder can be used both for cutting metal and as a circular saw

The second scheme, in which the part remains stationary, and the cutting wheel itself moves, is more convenient. The so-called pendulum saw, located above the table top, allows you to cut the workpiece exactly at the required angle, while it becomes possible to make the required number of similar parts. Due to the location of the grinder on top, cutting the workpieces is effortless, and the operation of the unit becomes simple and safe. The undoubted advantages of the design include the ability to quickly dismantle the grinder for traditional use. As for the disadvantages of this method, the weak link can be considered a hinge joint, which complicates the design of the machine.

The machine for cutting metal with an upper grinder has a more convenient design and makes it possible to cut blanks at the desired angle

Pendulum saw device from grinder

A pendulum saw from a grinder is available for assembly at home, does not require expensive materials and special qualifications. The cut-off machine has a simple design and consists of several units:

• bed;
• pendulum;
• mount under angle grinder.

The bed is a steel frame welded from shaped tubes with a sheet metal platform with a thickness of at least 3 mm. A bracket is attached to this plate, on which the hinge of the pendulum saw is mounted, as well as a stop for holding the workpiece. By the way, there can be several such stops: it is convenient when one element allows you to make a perpendicular cut, and the other makes it possible to cut the material at the required angle. The most perfect stop is a rotary device with a protractor, with the help of which any angle is set between the part and the cutting disc. An important detail: at the point where the saw touches the platform in the tabletop, a cut is made, its width should be equal to twice the thickness of the cutting wheel, and its length should correspond to the diameter.

The standard design consists of a frame, swingarm and grinder mount

The pendulum of the cutting machine is a T-shaped piece made of a rectangular metal profile. On the one hand, this unit is attached with a movable joint to the frame bracket, and on the other hand, a fastener for the grinder is attached to it. The movement of the pendulum saw joint is provided by rolling bearings or bushings, and the return of the tool to its original position is provided by a flexible element (rubber band or spring).

The grinder attachment is a console with one or two brackets connected to a pendulum. The angle grinder is bolted to one of them. For this, threaded holes are provided in the housing of its gearbox for attaching the handle. The second bracket is a regular clamp (ladder) that holds the cutting tool by the body.

Convenience in the operation of the equipment can be significantly increased by connecting the grinder to the foot switch-pedal. Of course, in this case, the lever for starting the angle grinder is brought into the working position and fixed with a special button.

Required tools and materials

When starting to manufacture a cutting machine, it should be understood that the accuracy of its work is directly related to the stability of the structure. Therefore, the choice of a material of a certain thickness is dictated not so much by the requirements for the strength of the case as by the need for its rigidity.

Before starting work, you need to prepare:

• profile pipe "square" (25x25x2.5 mm);
• profile pipe "rectangle" (40x20x2.5 mm);
• metal sheet 4–5 mm thick;
• ball bearings No. 202, 203 or 204 - 2 pcs .;
• a bar calibrated with a thickness equal to the diameter of the bore of the inner bearing race (up to 100 mm);
• a bar with a diameter of 8–10 mm;
• metal tire (20x4 mm);
• M8 or M threaded bolts and nuts.

Of the tools you will need:

• Angle Grinder;
• drill or drilling machine, a set of drills;
• a set of dies for cutting metric threads;
• open-end wrenches;
• welding machine.

The presence of electric welding is desirable, but not necessary - all connections can be made on threaded connections. However, it should be understood that this method reduces the reliability and strength of the structure.

For the manufacture of the machine, it is better to choose a grinder from a well-known manufacturer

The main unit of the cutting machine is the angle grinder. It is not recommended to use a "small" grinder designed for cutting discs with a diameter of up to 125 mm and a power of up to 500-600 W. Remember that the larger the diameter of the cutting wheel, the more versatile and reliable the machine will be.

The thoroughness of the choice of power tools is also due to the wide variety of grinders designs on the market. Since such equipment is not standardized, the cutting machine is built for a specific model and size of angle grinder. If the equipment is unreliable, then in case of failure it will be difficult to install another grinder in its place without the need to rework the mounts and the pendulum. That is why it is better to choose products from trusted manufacturers - Makita, Bosch and so on.

Making a cutting machine with your own hands

Preparatory stage

Work on a cutting machine begins with design. It is impossible to give the exact dimensions of the device, since the design depends on the model and size of a particular grinder. Nevertheless, according to the presented drawings, one can get an idea of ​​the dimensions and structure of the equipment.

The sketch of the project begins with a drawing of the case. You may not need a frame, but a separate platform that can be attached to a locksmith's workbench. In any case, the dimensions of the device and the location of the main units on the body are determined. Next, the angle grinder and the center distance of the mounting holes on the housing of its gearbox are measured. Based on these indicators, a drawing is drawn up for attaching the grinder to the pendulum. After that, the swivel unit itself is designed. The smaller the distance from the pivot to the cutting wheel, the stiffer and more accurate the machine will be. In other words, the length of the pendulum should be as short as possible.

At the last design stage, it is calculated how much and what material will be needed.

Drawing of a pendulum-type cutting machine. The dimensions of the base are indicated on the left. Pendulum design features are marked on the right.

Step-by-step instruction

1. In accordance with the drawing, the workpieces of the future machine are cut. Profile pipes are used for the frame and pendulum, and a metal profile, a metal tire and a steel bar are used for cantilever mounting. If the structure provides for a supporting platform, then sheet steel with a thickness of 4–5 mm is cut to size.
2. A transverse axis (shaft) for a swivel joint is welded to the pendulum arm, which is a section of a shaped pipe. In this case, it is important to ensure the perpendicularity of the shaft attachment to the pendulum.

   After cutting the material, the shaft is welded to the pendulum arm

3. A U-shaped bracket is bent from a steel tire, holes for bolts are drilled in its sides, with the help of which the gearbox housing of the grinder is attached.

   To attach to the threaded holes on the LBM gearbox housing, you will need a U-shaped bracket

4. A U-shaped clamp (stepladder) and a clamping bar for fixing the tool body to the pendulum are made from a steel bar. The latter is a metal plate 15–20 mm longer than the clamp width. The threaded ends of the ladder fit freely into the holes at the edges of the pressure plate, and the fixation is carried out with nuts with a suitable thread.
5. Trying on a U-shaped bracket and a clamp to the grinder, these parts are mounted on the console with a welding or threaded connection.

   This is how the console for attaching the grinder to the pendulum arm, complete with a U-shaped bracket and a clamp, looks like

6. The bearings, which will ensure the rotation of the pendulum, are pressed into the supports. As the latter, you can use both ready-made factory bearing assemblies and pieces of steel pipe (15–20 mm) with a diameter equal to the outer bearing race.
7. The bearing units are pressed onto the shaft from both sides. It is important that the connection is tight to eliminate unwanted longitudinal and lateral displacements. If the resulting connection is weakened for some reason, you can use a proven method - tin the axis with a soldering iron, applying a thin layer of tin on its surface (you will need soldering acid as a flux).
8. At a distance of 50-60 mm from the edge of the platform, a pendulum assembly with support nodes is welded. In this case, it is important not to overheat the bearings, so these parts are wrapped with wet rags or constantly watered with water to cool.

   The pendulum arm complete with bearing assemblies is welded to the platform at a distance of 50-60 mm from the edge

9. A console with an installed clamp and a U-shaped angle grinder is welded onto the pendulum arm. The position of the grinder is chosen based on personal preference. There are different opinions on how to attach the grinder ("from yourself" or "to yourself"). Professional locksmiths work with the tool, orienting the sheaf of sparks towards themselves, arguing that if the grinder falls out of the hands for any reason, the tool will fly off in the opposite direction. Hobbyists tend to work with medium or small grinders, so they prefer the disc to rotate "away from themselves", as this allows control of the cut and prevents damage to clothing. When securing the tool, do not forget to place the protective cover correctly - it must protect the worker in the event of a disc rupture.
10. An angle grinder is attached to the assembled machine. Focusing on the weight of the tool, the return spring is selected and installed. For this, hinges are welded to the bed and the pendulum or holes up to 5 mm in diameter are drilled.

    In order not to damage the plastic body of the grinder, strips of rubber are laid between it and the brackets

11. Carry out a trial run of the grinder. First, they check the operation of the machine in idle mode. At the same time, attention is paid to vibrations and backlash of the working parts of the equipment, which, if necessary, are eliminated.
12. Using the cutting wheel of maximum thickness, a groove is cut in the machine platform for the cutting disc. If necessary, the grinder is removed and the slot is expanded to the desired size.

    This is what the improved stop with clamping device looks like.

At the last stage, workpiece stops are attached to the platform. Most often, two strips are provided (for a cut at an angle of 45 and 90 degrees), fixing them using a welded or threaded connection.

Often, devices for holding the workpiece are provided with a measuring tool. By attaching a metal ruler to the stop bar with a reference point from the grinder's disk, you can quickly and accurately cut a part of the required length. Also, if desired, you can install protractors, vices and clamps of various designs. Such additional details allow you to make, for example, a full cut or groove in the workpiece at any angle, free your hands, and so on.

Do not forget to paint the fixture after all the finishing activities have been carried out. Even a thin layer of enamel will protect the equipment from rust and make its appearance more aesthetically pleasing.

Safety engineering

In the process of working on the cutting machine (as well as during its operation in the future), safety precautions should be strictly observed. Be sure to use a protective mask or goggles, and position the angle grinder so that the spark is directed "away from you." The high fire hazard of the equipment requires work in a ventilated area and away from fuels and lubricants. During welding, a protective mask, thick leather gloves, closed shoes and protective coveralls should also be worn.

When working with the cut-off machine, do not try to speed up the process by over-pressing the tool. In the best case, such a rush can end with a torn disc and a jammed nut of its clamp.

Ensure good grounding when using the welding machine and avoid operating the equipment with exposed cables. Remember that welding in open areas in rainy weather is prohibited. As for the operation of the cutting machine, then when arranging the button to turn it on, secure yourself by installing a simple decoupling with a 12-volt power relay. To do this, you can make a pedal with any non-latching switch (for example, a button from a doorbell) and use any solid-state relay designed for switching currents of at least 10A. A battery or accumulator with a voltage of 5 to 24 V is used as a power source.

A cut-off machine from a grinder is a convenient tool that can be easily made if you have the skills to work with electric welding and locksmith tools. A pendulum circular saw made in just one day will save time in the future and will allow you to perform locksmith and welding work accurately and accurately.

Cutting metal or other hard materials is done with an angle machine, which is popularly called a grinder. This fairly simple tool allows you to cut many materials with different types of discs. However, holding the angle machine in your hands does not always achieve an even cut.

For this reason, there are many different devices, thanks to which it is possible to fix the grinder and make more accurate sawing. But basically these are pendulum-type devices that allow you to cut workpieces across, at a certain degree, both vertically and horizontally.

As for cutting sheet blanks in length, it is rather necessary to use a technology similar to circular hand saws. There are such devices on sale, although with some skills, you can do this yourself. It is important to understand the principle of operation of such a device. And if it is necessary for you to do something similar in your work, using materials that you have or are more available.

There are two options here. At the first, it is to fix the grinder under the table, leaving a part of the cutting disc from above through the slot. This may be easier, but if the workpiece does not run smoothly or if it is quite heavy, then the cutting disc can wedge and break. Therefore, this option is used for sawing wood with a metal circular saw.

With regard to sawing sheet or other metal in length, here you need a device that fixes the grinder on a sliding bed, such as the known circular saw, with the ability to adjust the cutting depth.

As a guide, you can use both simple rails or metal corners attached to the table using clamps, and complex devices that have bearings on the carriage that roll along the guide. It is clear that the design will be developed taking into account frequent or single use.

It is important, with such a cut, to set up the entire mechanism. It is important that the cutting disc runs parallel to the cut, which is not always the case when installing the grinder on the device. Therefore, you need to pay attention to this, since the disc rotates at high speed, which is not safe, plus if the cut is not even, the cutting width increases.

A carbon grinder (angle grinder) can be one of the most useful and versatile machines when you get the most out of the attachment. It's important not to forget how to use your angle grinder. Unlike a drill (rotation 700-1200 min -1), angle grinders have a rotational speed of up to 12,000 rpm, so it is important to observe some basic precautions.

Features of using the grinder

Safety goggles, heavy gloves, safety boots and a dust mask must be worn. Tile fixtures are great for cutting directly onto ceramic or stone tiles. However, you will find it difficult, if not impossible, to make precise cuts for the workpiece around obstacles. Do-it-yourself attachments for an old grinder easily cope with these complex tasks.

If you cut the bolt flush into concrete or other material. Attach the long side of the rack firmly, making sure it is in real estate. The part of the workpiece that will fall out after the cut can injure the legs.

With the right disc, your grinder can be used to repair rough edges on many household appliances, including lawn mower blades, shovels, hoes and even axles. After that, you can always modify the finish with the mill file.

It is advisable to use a grinder to work on removing peeling paint, dry cement or rust from metals. There are numerous wire brush rims, all designed for different types of stripping, cleaning and deburring. Check the manufacturer's description before making a purchase.

If you have a lot of removal solution and the hammer and chisel simply won't pick it up, you can use a grinder. Using a corner fixture to dismantle old mortar will result in a lot of dust. A dust mask is required.

Fixture technology is designed to work with a variety of materials to achieve a variety of finishes and effects. By choosing the right cutter wheel, you can accomplish an even greater variety of household tasks, including polishing, buffering, sanding, rounding, and shaping. Do-it-yourself grinder attachments can significantly expand the forms of application.

Materials and tools to make grinder attachments

Angle grinder wheels and discs can be made from a variety of materials. However, in general, a diamond blade will provide maximum precision and polish. Wheels are available in a range of abrasion (or sand) levels. Use a higher abrasion accessory for rougher polishing surfaces.

However, despite all this, many people still decide to create accessories for Bulgarians with their own hands. If you decide to independently create adaptations for a working grinder for, then before starting work you need to prepare the necessary tools:

1. An electric drill is desirable.
2. Set of drills.
3. Discs should be selected with a diameter of 125 mm.
4. Wooden blanks.
5. Metal corner.
6. Steel plate.
7. Self-tapping screws.

When it is necessary to use a grinder for specific tasks, in this case, many craftsmen make a choice in favor of ready-made applications. They can be bought without any problems at a construction supermarket. The cost of the devices is not very expensive.

Stand for grinder

No matter how skilled a craftsman is, he needs the perfect attachments to get his job done. The grinder stand is provided as a great tool for perfecting these corner pieces.

The grinder's stand allows you to grind at perfect angles 115mm-125mm. If the rack is made of aluminum alloy, this allows you to have a fixture that will undoubtedly last a long time.

Get more out of your angle grinder with a convenient holder. Angle grinders are dangerous tools. Homemade grinder jigs will allow you to have more control over them, but still we must use all the necessary protective equipment such as safety glasses and gloves.

What you need:

• Woodworking accessories.
• A piece of hard plywood 300 × 100 × 20 mm.
• A piece of hard plywood 150 × 100 × 20 mm.
• 1 x M12 screw, 30 mm long.
• 2 washers M12.

The design is very simple, you only need to form a 150X100X20 part, adapt it to the shape of the grinder.

There is a fixture and simple drawings for the grinder, which can be created with your own hands. The grinder stand is very useful in the metalworking workshop, as well as in woodwork.

Parts used:

1. Metal base plate.
2. 3 "C- Section angle 2 pcs.
3. 1 "L- Section angle 4 pcs.
4. Door bracket.
5. Rigid spring.
6. Nuts and bolts.
7. Hardware.

How to do:

• Step 1: Create the base of the stand. The first step in creating a do-it-yourself cutting machine is its base. The entire stand will be made of metal. The base plate and L-shaped metal parts will be used to make the base. The required thickness of the base plate is 3 mm, for the best performance of the stand. The first step is to cut the L-section into four pieces equal to the four sides of the base plate. Then glue the base plate and L-section together. Make sure the seam is perfect and accurate.
• Step 2: C- section for holding the angle grinder. The retention capacity of the C-section channel is very high. A metal piece is welded with this C-section to hold the angle grinder with the bolt or handle of the angle grinder.
• Step 3: - Another part of the C-section. The metal piece at the end of the C-section is welded.
• Step 4: - Attach both parts of the C-section.
• The door bracket is used to secure both parts of the C-section.
• Step 5: - Attach the springs and the whole assembly. This entire assembly is now attached to the base with two bolts. Then attach the spring.
• Step 6: - Holding the workpiece.

This is the final step in making an angle grinder. A long bolt and an L-section channel can be used to make a workpiece holding device. Two hex head bolts are used to secure the L-section channel to the base.

The wall chaser from the grinder allows you to do tracing on all building materials with your own hands in absolute safety and in the absence of dust. This wall mount is very useful when you need to make cuts for piping, place cables for electrical systems, and for installing pipes for hydraulic systems.

The saw blade, mounted on the shaft, is the main element of the device. To ensure safety, the discs are mounted inside a special case, which prevents fragmentation and receiving them personally when cutting.

Depending on the properties of the material and density, it is recommended to choose the engine power for the wall chaser from the grinder with your own hands. A modest block is sufficient for the cable furrow. For a long pipe groove, it is advisable to purchase a grinder with a power of at least 2000 watts. Some high-performance models are capable of reaching speeds of about 6,200 rpm, which guarantees the ability to cope with an industrial scale.

But the design of the grinder is such that it cannot be used due to the active formation of dust. They often resort to modernizing the device.

You can design a device with two discs. Installing the machine from a suitable do-it-yourself grinder of this type will cost more. The first drive is attached as usual and the second is mounted. A second nut is required, which has an additional ring to secure it. When working on a wall, the sander should be in the protective cover.

Since any angle grinder is equipped with a powerful geared motor, it can be used as a stationary milling cutter. Provided that the machines from the grinder with their own hands at any time can remove the device for use for its intended purpose. The grinder shaft is brought out into the hole of the workbench, a chuck for milling heads is put on it - and you can process not too hard wood species.

• Step 1: Create an angle grinder bracket. You can use the threaded holes in the grinders as anchor points for the bracket. There are many ways to approach a pen, depending on the type of grinder you decide to work with. Critical measurements are needed to put together a functional design that allows the grinder to be easily detached for handwork. It took five pieces of a flat metal rod to assemble the device. Welding them together created a custom bracket. It is necessary to weld a short armature as a rod to attach the wooden handle.
• Step 2: Create a clamp that firmly holds the handle of the grinding head against the head of the adjusting bolt.
• Step 3: You will then need to attach a leg to the front end of the rods to secure the grinder's bracket by enabling the hinge function to allow the grinder to pivot towards the cutting table.
• Stage 4: Creation of the base. It is possible to use a simple frame using tubes and mount them with two pieces of iron. It is necessary to form a flat platform for fastening the slider mechanism.
• Stage 5: Build.
• Step 6: Add a cutting table. The cutting table consists of a steel plate. After all parts are assembled and adjusted, level the vertical surface of the cutter wheel.
• Stage 7: Final testing.

Clip for grinder

Create a wooden box. You will need a base for this model. You can use wood and use liquid nails. But you can use a plastic, metal or wooden box.

Check if the angle grinder is suitable

Make sure the grinder's fuse does not react when you attach the grinder and make sure the fuse is flush with the box. Attach the grinder and check the work.

Grinder miter box

The miter box from the grinder makes the work with the device much easier.

Material:

• iron plate 1 × 200 × 100 × 2 mm;
• iron rod 2 × 150 × 30 × 3 mm;
• iron rod 2 × 40 × 30 × 3 mm;
• iron rod 2 × 30 × 30 × 3 mm;

• screws 1 × 7 × 50 mm;
• 3 × 7mm nuts;

How to do:

• Step 1: Create the base of the stand.
• Step 2: preparing the material
  • Adjust the dimensions of the metal plate 200 × 100 × 2 mm so that the sides are at right angles (90 °);
  • It is necessary to cut 2 blanks of an iron bar 40 × 30 × 3 mm;
  • Mark the center and drill a 10mm hole on one side. The hole must have a diameter of 7 mm;
  • Cut two pieces of 150mm iron;
  • These blanks require 3 holes. The hole must be located 10 mm from the edge;
  • The holes must match the bolts;
  • The shaping of the rods is necessary according to the grinder to fit the profile of the machine;
  • Cut one piece of 30mm iron rod. Drill a 7 mm hole.
• Step 3: Launching the Bracket
  • Then screw these parts into the machine and adjust them. One will be fixed in the right side hole and the other will be fixed in the top hole;
  • Then give a soldering point;
  • Then weld another 30mm piece already drilled. For easier alignment, use a 7mm screw to secure them. Then it is necessary to weld (give only one connection point) a piece of 30 mm iron rod on the side.

At this stage, it is important that the final part is at right angles.

• Step 4: Base
  • Take 2 pieces of 40 × 30 × 3mm iron bar and place them on the sides on both sides and replace the screw to join them together and make soldering easier.
  • Position the attached set of brackets and sides on the plate so that it is more offset to the right. There should be a slight difference on both sides.
  • Then it is required to weld the elements of the device (give only one soldering point) on both sides. Make the necessary adjustments. There should be no excessive displacement.
  • To facilitate movement, two washers are intelligently fitted between the side and the handles.

• Step 5: Completing the Build
  • Observe whether you move freely, and the angle can reach - 90º.
  • After checking alignment, carry out a final weld.
• Step 6: Processing the base. Mark the cut. Start by gluing the corners and finishing with a saw.
• Step 7: Base with grinder installed. Take advantage of the handle support that already accompanies the hardware and replace the originally installed screw.
• Step 8: Screw depth hole. The screw allows you to adjust the depth of the cut. Pay attention to the longitudinal and lateral alignment of the disc.
• Step 9: Reminder. Remember that this instruction is for a grinder with three factory holes. This allowed the machine to be secured in the support, and the third hole adjusts the depth of cut during operation.

Sawing device for porcelain stoneware

By tilting the fixture, you can easily check expensive material. It is advisable to use special machines to accurately adjust the movement of the fixture. It is possible to make the necessary mechanism from an old grinder.

For such a technique, the installation of several guides on the platform is required, followed by movement along the intended trajectory. Also, a homemade device will allow you to change the cutting angle and depth of processing. To create a machine for porcelain stoneware, you will need proven drawings and experience.

How to make a bed for a grinder

The grinder can be used for grinding or cutting when changing the necessary attachments, according to the principle of a circular saw. Thus, it is possible to process pipes and workpieces even with large diameters along an even cross-sectional angle.

To create a bed, you need:

1. Bulgarian.
2. Drill.
3. Welding fixture.
4. Steel plate.
5. Steel plate 3 mm thick.
6. 40 × 40 × 5mm square tube.
7. L-profile 30 × 30 × 3.
8. 80mm screw, nut, two screws, spring washers.

• Step 1. It is necessary to cut parts of the required size and clean the edges from chips and irregularities.
• Step 2: Easy attachment for the angle grinder.
  Next, you need to create handles on both sides for the grinder, which will increase the number of possible positions during operation.
  The grinder handles can be angled slightly instead of pointing straight up and down for a comfortable grip. The clamp that connects the handles to the grinder can be V-shaped, which will create optimal conditions for excellent work. This shape makes this simple structure robust enough without the need for additional connections. To connect the new module, factory threaded grooves at the grinder are used. Before welding, simply install these plates and the screw (to disassemble the joint if necessary) with an angle grinder. Keep the blade in place and use a right angle for backing.
• Step 3: Make an extra position for the handles.
  A hole is made large enough for the thread of the handle to screw securely into the grooves (10 mm). Cut off the handle required for the base shape and secure the nut to the drilled hole.
  Next, you need to weld the elements. Place and shape it so that you can still hit the Lock Disk button. This way, you can change the new drive without having to uninstall your application.
• Step 4: Create the bottom plate.
  You need to create 8mm holes for the "back stop", this is the 30x15mm L-profile part mentioned earlier. Connected to it with butt welds. This way the bottom plate stays straight and the result looks better.

• Step 5: Connect to the bottom.
  Connect these two parts of the metal module together.
  A simple "hinge" of a 40x40x 5mm piece of square tubing can be used.
  Drilled hole with a diameter of 12 mm to the center of the side, through both surfaces. The product is welded.
• Step 6: The material is pushed off the "back foot" so that the angle grinder is suitable for moving down vertically. Welds need to be cleaned with a steel brush and finally painted in the desired color.

Tripod for angle grinder

Personal LBM Attachments transforms the angle grinder into a versatile and precise cutting attachment for steel, metals, profiles, pipes and rods. This unit has versatile applications and fits most common angle grinders. The clamp for the grinder has received various forms of execution. You need to create universal adjustable angle grinder mounting brackets. Provide protection against metal sparks.

Protractor for grinder

When working with a metal profile or important parts requiring even seams, it is effective to use a protractor for a grinder. The use of the device allows even an inexperienced person to create an incision exactly with a given slope. The protractor is indispensable when working with ceramic tiles and skirting boards. If desired, they often create a homemade protractor for homework with a sander.

To begin with, they carry out the installation of a guide angle, equipped with a special overlay on a flat surface (ceramic tile). This is done in order to secure the workpiece and prevent displacement. The workpiece is pressed tightly, after which the required angle of inclination is adjusted.

After that, the master proceeds to sawing the workpiece, slightly pressing on the disc.

In the design of a protractor with your own hands, there are three main components:

1. Corners.
2. Hinges.
3. Pain for fixation.

The principle of operation of the protractor is to install a special guiding angle with an overlay on the processing workpiece. Creating an accurate protractor is a rather laborious process.

Grinder bench grinder

Required fixtures and materials:

• grinder with abrasive disc;
• racks (16 mm);
• a small piece of scrap (square or rectangle from 12 to 25 mm);
• plywood (6.5 mm);
• hand saw;
• drill with assorted drills;
• reciprocating saw or copy saw;
• optional, but highly recommended.

• Step 1: Design. This model is for a cheap sander. Think over all the details.

• Step 2. Getting started. It will take a base and some support to get your grinder high enough to clear the wheel. Processing can be carried out using a hand saw.
• Step 3: support. Mark and cut out the 2 side supports, then forward and secure with screws, pre-drill them (dimensions may vary).
• Step 4: drill and fastening. Next, you need a bolt that fits into the hole for the handle of your angle grinder.
• Step 5: Rebuild the fixture. Now you need 2 sides. Where the scrapers will make the circuit stronger, but if you don't have the fixture, it will work without them.
• Step 6 Dowel pile. A tongue is a groove or groove in the edge of a piece of workpiece material for attaching another board; there are several ways to add this. The simplest of them will be with a table saw, but if it is not possible, another way is possible. Method 1. Mark where you want to get the tongue, pinch the piece and use the saw, cutting gently on the side of the line. If you want to make this easier, you can take a piece of wood and place it on the side of your line to create an obstruction. You can keep making cuts along the side until you get to the end, and then cut out what is left of the excess material.
• Step 7: Method 2. This method is much faster and more accurate if you have a router, you can make a small table for it.
• Step 8: Combine the elements. Now fit your 2 sides and measure the top of the product, cut out the required cover and install.
• Step 9: strap. One bolt is not enough to hold the angle grinder. The bolt is exposed to the flow on it, so find some strapping material, duct tape. Such items will work if you have absolutely nothing. You can use a small strip of metal.

The master made this device for cutting, faced with a problem, in order to smoothly dissolve the sheet metal into strips with a grinder, while having a sufficiently high-quality and even cut edge. I looked on the Internet how this issue is being resolved, I borrowed a lot, that you added your own. It turned out to be a handy tool.

Device for neat cutting of metal

Grinder 1300 watts, mounted on a homemade rail with bearings. They move along a 40 x 40 square that acts as a rail. It turned out 7 pieces. Fixed on the rail from 4 sides, 2 between them, and one below moves along the plane. The grinder was installed on the guide with the help of a fastener, fixed with a handle. On the other side with a bolt. There are slots here, you can choose the height of the disc.

There is a small nuance.

To get a high-quality cut and avoid biting the disc, you need to very evenly set the angle grinder and the disc vertically. Side mounts are not enough for this, because the grinder slightly changes its position to the right or left under load. For this, the master did the following. To avoid this, there are holes in the lid of the grinder, exactly the same for the handle. He screwed a bolt into it, fixed it with a nut. I drilled the same hole in the plate exactly parallel, screwed in a bolt, and fixed it with a nut on both sides. Set up an even vertical position. Tightened two nuts on 2 sides. Added a bottom bearing. The height was already known after fixation. Got four points. The grinder is very firmly and firmly established, no backlash or swinging occurs during movement. This allows you to cut thick metal - five, six.

In terms of safety, I added a cover, since the front side disk is located to the working one. If a disc is found to be of poor quality, or it gets bitten so that, even if it scatters, the fragments do not hit the person, added protection. I screwed it to my family.

There were no problems with replacing the disc, the distance allows you to insert the key, unscrew the nut, change. Added a top rail. For what? It happens in the process of work that the disc bites or bites. Since the revolutions are high, the entire structure, together with the angle grinder, can fly off the lower rail. To prevent this from happening, I added this rail. The height is adjustable with a bolt. For smooth running, I added bearings on both sides.

Guide for a straight cut angle grinder

Let's make a simple grinder attachment. An idea has been spinning in my head for a long time and I decided to bring it to life.
The device is simple, so a minimum of materials are required. The first and foremost is the grinder itself. The author of the homemade product uses a rechargeable one, but it turned out to be weak. Therefore, he recommends the usual 220 volts.
A piece of a profile pipe 40 by 60 millimeters and a length of 150 and a profile pipe with sides of 25 millimeters. The length can be taken to suit your needs. For example, I decided that a piece 1 meter long is enough.

We start with the markup. From a pipe 40 by 60, you need to cut a corner with sides of 50 by 35 millimeters.
Cut out the rest of the pipe. Cut off two more strips 25 and 20 millimeters wide. When all the blanks are done, proceed to welding.
We wrap the profile pipe with a sheet of paper to make gaps between the parts to be welded and the pipe. We expose all the blanks, as shown in the video. We clamp with clamps and grab. You can scald everything and grind the seams.
The detail on us turned out.

This is a carriage rail for smooth cuts in sheet metal and more.
We will fix the carriages. I'll weld in two strips of metal with holes for fasteners. It is better to weld in place, so we fasten the strips to the patient and grab them. And then you can paint.
Install the helmet and proceed to the tests. We will cut a piece of 3 mm metal. I secured the guide rail with two clamps.

The device works. I regretted that I had installed the carriage on a cordless angle grinder. It is much weaker than the network one. Most likely, the carriage will later be converted into a network carriage with a 125 mm disk.
A smooth cut is obtained using a tool.

The grinder is a useful and versatile tool. It is suitable for cutting metal, stone, tiles and, sanding surfaces. However, sometimes there are situations in which a stationary machine is more suitable for these works. It is good that using certain accessories for the grinder, it can be turned into a cutting machine.

Finding a finished machine that meets your needs in stores is not difficult. However, the likelihood of finding a structure that rigidly fixes the grinder and does not dangle during operation is not great, since they are all made of duralumin. For this reason, many people prefer to make various accessories for the grinder with their own hands.

When performing construction and installation work, a large number of very different tools are used. The most commonly used grinder. The main task for which it is used: metal cutting; processing of building materials.

If you also use attachments with this tool, then you can expand the number of options for its use. In particular, using this tool with attachments, you can perform high-quality grinding the bases of the blanks. They will be cleaned of foreign inclusions. Grinder attachments can be purchased at the store. But if you have no desire to pay money, then you can make it yourself.

In some cases, this tool is used as a wall chaser. With his help grooves are created for laying pipes and electric wires. To use the grinder in this capacity, you will have to perform some manipulations and increase the standard width of the protective casing. In addition, you will need to make a support plate.

Such a tool can be used with one disc or several at once. If the grinder is used with two discs, then it is necessary to make some changes to the attachment point of this tool. After that, the grinder can be used in standard mode.

It often happens that during repair work there is a need to clean the base of parts that are difficult to access. In such cases, craftsmen most often resort to using a home-made device for a grinder in the form of a special nozzle, thanks to which a small disc can be carried out beyond the dimensions of the grinder.

In this case, the rotation will be transmitted using special belt drive from the main drive. Using such a structure, cutting of materials cannot be performed. However, it is possible to remove scale from the surface of materials without any problem. It often occurs on the surface of the weld seams.

At the moment, the market offers a large number of attachments for tools such as a grinder. Their use allows you to significantly expand application options this tool. If we talk about the most commonly used grinder attachments, the following can be distinguished:

• a device for sanding the base and removing the paint layer from the surfaces of materials;
• bed;
• protractors.

Materials and tools to make grinder attachments

When it becomes necessary to use a grinder for specific tasks, then in this case, many craftsmen make a choice in favor of ready-made nozzles. They can be purchased without any problems at a hardware store.

The cost of the devices is not very high, so everyone can afford them. There are no difficulties with the search for these attachments either. However, despite all this, many people still decide to make do-it-yourself grinder attachments.

If you decide to make attachments for this tool yourself, then before starting work, you need to prepare the following tools:

1. An electric drill, it is advisable to purchase a set of drills in addition to it;
2. It is advisable to choose discs with a diameter of 125 mm.
3. Wooden bars.
4. Metal corner.
5. Duralumin steel plate.
6. Self-tapping screws.

Work technology

Before starting work, it is necessary to cut a plate out of the metal. After that, you need to make a corner out of it. To carry out your plan, you must first do triangle neckline in the workpiece shelf. And when this is done, the workpiece must be bent at right angles.

Further, in the design of the plate follows drill six holes... The diameter of each of them should be 4 mm. Subsequently, it is in these holes that self-tapping screws will be installed. With their help, it will be possible to fix the handle, corners and timber. All holes must have special grooves for the screw heads.

To securely fix the handle of the bar, several self-tapping screws are enough. Fasteners used during this work should measure 3x35 mm. This will produce an L-shaped part.

After that, all the elements together with the plate are compiled into a single structure. The created tool attachment must be fixed using self-tapping screws 3x20 mm.

So, the basis for the future design has been completed. Next, you will need to execute installation of metal corners... You should have several of these items in stock. They must have the following dimensions:

• 75x30x55 mm;
• 45x60x60 mm.

Please note that the first corner must be extended to 60 degrees... If this is not done, then it will not work to achieve its main goal - to fix the manufactured structure on the grinder. When the installation of the metal corners is completed, the tool itself is fixed directly to them.

To connect the tool and structural elements, use a separate handle on one side, and bolts with nuts, on the other side. The latter are necessary so that during the work there is no loosening of the screw of the structure.

If you wish, you can refuse to mount the nut on the handle, since it will be held by the hand of the master during work. At this point, the work on creating a structure for cutting can be considered complete.

How to make a bed for a grinder

Often grinders are used in conjunction with a bed. They are used mainly to enable the foreman to perform certain work on cutting materials and workpieces with less physical effort.

It is obvious to everyone that it is extremely difficult to hold a heavy instrument for several hours. Therefore, to facilitate their work when performing the operation, many masters make special devices, which are called beds. When the grinder is equipped with such a device, the cutting work can be done with only one hand.

To make a bed, you first need to make a wooden box... You can get by with only one side on which the tool will be fixed. All other walls can be removed, and instead of them, legs of a special design can be attached.

But in order to achieve the efficiency of using a grinder with such a device, it is necessary to make some changes to its design.

The first step is to complete dismantling the grinder casing... After that, the disc must be put on the instrument. When this action is completed, it must be pressed against the side wall of the device.

It is necessary to put a mark where the clearance was made for the travel of the nozzle or disc. Its width should not be too large, otherwise foreign objects during work may get inside the structure.

The gap can be increased if desired. The need for this arises in cases where it is necessary to replace the nozzles without completely disassembling the entire structure. Sample wood blocks can be used as support elements. After that, you can start cutting the workpieces.

Protractor for grinder

When conducting construction and installation work, an important tool for the grinder is a protractor. It is especially indispensable when working on processing or cutting metal profiles.

By resorting to the use of such devices, you can easily calculate cutting angles blanks. And this has a positive effect on the speed and quality of the work performed. In addition, such a device is suitable for cutting metal profiles.

• The construction of this type is widely in demand when working on the processing of wall and floor tiles.
• They are also used for cutting and processing floor coverings and skirting boards.

Having made a protractor for a grinder with your own hands, you will no longer need to purchase special tools, which are quite often expensive and have large dimensions. A homemade protractor is not suitable for industrial use, but for home use it will be an excellent replacement for store accessories.

The principle of operation of the construction of a homemade protractor

The first thing to do is install the guide angle equipped with a special overlay on the tiles. A similar pad is used in order to prevent the workpiece to be fixed from sliding. Therefore, thanks to it, the offset of the element will be excluded.

Then you need to tightly press the workpiece to the corner shelves. After that, the user must set the desired cutting angle.

Next, you can proceed to cutting the material. When performing this action, it must be borne in mind that when cutting, it is necessary to press down on the blade slightly. No serious physical effort is needed.

A homemade protractor for a grinder has a structure consisting of the following elements:

1. Corner.
2. Hinges.
3. The bolt used for fixing.

Note that it is quite difficult to make such elements with your own hands. Therefore, if you are not sure that you can cope with such a task, then it is better buy in the store ready-made models transported.

The grinder is a fairly popular tool among builders and repair specialists. It can be used to cut various materials and handle workpieces and parts... However, sometimes specific operations are required. Therefore, experts purchase special attachments for the grinder. They can be found in stores without any problems.

The use of such devices allows you to expand the number of options for using this tool. However, it is not always necessary to buy them from hardware stores. If you wish, you can make them yourself. To do this, you just need to have free time and know how to make the right attachments for the grinder.
