Do-it-yourself device for a small angle grinder. Attachments for the grinder can be bought, but it is better to do it yourself. How to make homemade tools for grinders? Cooking Tools
Bulgarian is a useful and versatile tool. It is suitable for cutting metal, stone, tiles and grinding surfaces. However, sometimes there are situations in which a stationary machine is more suitable for these jobs. It's good that using certain tools for the grinder, it can be turned into cutting machine.
Finding a ready-made machine that meets your needs in stores is not difficult. However, the probability of finding a structure that firmly 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 fixtures for Bulgarians with their own hands.
When performing construction and installation work used a large amount of different instrument. The most commonly used grinder. The main task for which it is used: metal cutting; processing of building materials.
If you also use nozzles with this tool, you can expand the number of options for its use. In particular, using this tool with nozzles, you can perform high-quality grinding workpiece bases. They will be cleaned of foreign inclusions. Nozzles for grinders can be purchased at the store. But if you do not have the desire to pay money, then you can make them yourself.
In some cases, this tool is used as a wall chaser. With his help grooves are created for laying pipes and electrical wires. To use the grinder in this capacity, you will have to perform some manipulations and increase standard width protective cover. In addition, you will need to make a plate for support.
Such a tool can be used with one disk or several at once. If the grinder is used with two discs, then some changes must be made to the mount of this tool. After that, the grinder can be used in standard mode.
It often happens that during repair work and 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 fixture for a grinder in the form of a special nozzle, thanks to which the disk small size 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 this design, cutting of materials cannot be performed. However, scale can be removed from the surface of materials without problems. It often occurs on the surface of welds.
At the moment, the market offers a large number of nozzles for such a tool as a grinder. Their use allows expand application options this tool. If we talk about the most commonly used attachments for grinders, we can distinguish the following:
- a device for sanding the base and removing the paint layer from the surfaces of the materials;
- beds;
- protractors.
Materials and tools to make nozzles for grinders
When it becomes necessary to use a grinder for specific tasks, in this case, many craftsmen opt for ready-made nozzles. They can be easily purchased at a hardware store.
The cost of devices is not very high, so everyone can afford them. With the search for these nozzles, there are no difficulties either. However, despite all this, many people still decide to make nozzles for the grinder with their own hands.
If you decide to make nozzles for this tool yourself, then before starting work, you need to prepare the following tools:
- An electric drill, it is advisable to buy a set of drills in addition to it;
- It is desirable to choose discs with a diameter of 125 mm.
- Wooden bars.
- Metal corner.
- Plate of duralumin steel.
- Self-tapping screws.
Work technology
Before starting work, it is necessary to cut a plate from the metal. After that, you need to make a corner out of it. In order to accomplish what you set out to do, you must first triangle cut in the workpiece shelf. And when this is done, the workpiece must be bent at a right angle.
Further, in the design of the plate it 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 recesses for the screw heads.
To securely fasten the beam handle, a few self-tapping screws are enough. Fasteners used during this work should have dimensions of 3x35 mm. This will get the item G- figurative form.
After that, all the elements are combined into a single structure together with the plate. The created fixture for the tool must be fixed with 3x20 mm self-tapping screws.
So the base future design made. Next, you will need to do installation of metal corners. You should have several of these items available. 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 setting metal corners is completed, the instrument itself is fastened directly to them.
To connect the tool and structural elements, a separate handle is used on one side, and bolts with nuts, on the other side. The latter are necessary so that during the work there is no unscrewing of the screw of the structure.
If desired, you can refuse to mount the nut on the handle, since it will be held by the hand of the master during operation. At this point, the work on creating a structure for cutting can be considered completed.
How to make a frame for a grinder
Often grinders are used together with a bed. They are mainly used to ensure that the master performs certain works for cutting materials and workpieces with less physical effort.
It is obvious to everyone that it is extremely difficult to hold a tool that has a lot of weight for several hours. Therefore, to facilitate their work during the operation, many masters manufacture special equipment which are called beds. When the grinder is equipped with such a device, then cutting work can be done using only one hand.
To make a bed, you first need do wooden box . You can get by with only one side on which the tool will be fixed. All other walls can be removed, and legs of a special design can be attached instead.
But in order to achieve the effectiveness of using a grinder with such a device, it is necessary to make some changes to its design.
First of all, you need to do dismantling the casing of the angle grinder. After that, the disc must be put on the tool. 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 gap was made for the stroke of the nozzle or disk. Its width should not be too large, otherwise foreign objects during work, they can get inside the structure.
If desired, the gap can be increased. The need for this arises in cases where it is necessary to replace nozzles without completely disassembling the entire structure. Samples of wooden blocks can be used as support elements. After that, you can begin to work on sawing blanks.
Protractor for grinder
When conducting construction and installation work, an important device for an angle grinder is a protractor. It is especially indispensable when working on processing or cutting metal profiles.
By using these devices, you can easily calculate cutting angles blanks. And this has a positive effect on the speed and quality of work performed. In addition, such a device is suitable for cutting metal profiles.
- The design of this type is widely in demand in the processing of wall and floor tiles.
- They are also used in cutting and processing floor coverings and skirting boards.
Having made a protractor for an angle grinder with your own hands, you will no longer need to purchase special tools, which are 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 fixtures.
The principle of operation of the design of a homemade protractor
The first thing to do - install guide rail, equipped with a special overlay, on the tile. A similar overlay is used in order to prevent slipping of the workpiece to be fixed. Therefore, thanks to it, the displacement of the element will be excluded.
Then you need to firmly press the workpiece to the shelves of the corner. 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 taken into account that when cutting, it is necessary to press lightly on the disc. Serious physical effort is not required.
A homemade protractor for a grinder has a design consisting of the following elements:
- Corner.
- Loops.
- Bolt used for fixing.
Note that it is quite difficult to make such elements with your own hands. Therefore, if you are unsure that you will cope with such a task, then it is better buy in the store finished models protractor
The grinder is a fairly popular tool for builders and repair specialists. It can cut various materials and process workpieces and parts. However, sometimes specific operations are required. Therefore, experts acquire special nozzles for the grinder. You can easily find them in stores.
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 in hardware stores. If you wish, you can make them yourself. To do this, you just need to have free time and know how to properly make nozzles for grinders.
Bulgarian is an indispensable tool for construction, installation and other work. The main task of this design is to cut metal or stones with high speed. If you use special nozzles, you can carefully grind the base of the workpiece, clean it and remove it. various pollution. However, in order to be able to use this tool in other areas, you will need to buy or make homemade devices for Bulgarian.
In some cases, the grinder is used as a wall chaser. To do this, you will need to increase the width of the protective casing, and then make a plate for the support. Such a tool can be used both in a set with one disk, and with several. IN last case you will definitely need to improve the attachment point. If necessary, the upgraded cover with the supporting element can be easily removed, and then use the angle grinder in normal mode.
It happens that you need to clean up hard-to-reach grounds. Masters for such purposes use a special nozzle, which is able to take out a disk of small diameter beyond the dimensions of the grinder. Rotation in this case will be transmitted from the main drive using a special belt drive (rubber belts are used). Cutting using such a design will not work, but you can easily remove scale from the weld seam.
Today, there are a fairly large number of different nozzles with which you can expand the scope of this tool. Among them, the main ones are the following:
- devices for sanding the bases and removing the old layer of paint;
- beds;
- protractors.

What do you need to make homemade tools for grinders?
Most owners prefer to purchase ready-made nozzles in building supermarkets. Such elements are not too expensive, and there should not be any problems with the search for devices. However, some people prefer to make similar parts for the grinder with their own hands.
In order to make devices of this type, it will be necessary to purchase items such as:
- electric drill with a small number of different drills;
- screwdriver;
- hacksaw for working with wood;
- discs for grinders, the diameter of which is 125 mm;
- wooden bars;
- metal corner;
- duralumin steel plate;
- self-tapping screws.
First of all, you need to cut a plate of metal. Next, make a corner out of it. To do this, you need to make a triangle-shaped cutout in the workpiece shelf and bend it at a right angle. In the design of a metal plate, you will need to drill 6 holes with a diameter of 4 mm. Self-tapping screws will be installed in these holes, which can fix the handle, corners and a wooden beam. All holes must have special recesses for the screw heads.
The handle is attached to the bar with several screws. The dimensions of the elements for fasteners should be 3x35 mm. As a result, it will be possible to obtain a part in the shape of the letter G. All elements, together with the plate, are assembled into a single structure. Attachments for the grinder must be fixed with several 3x20 mm self-tapping screws.
On this stage the base of the structure has been completed. Next, you need to install metal corners. There should be several similar elements, with dimensions of 75x30x55 and 45x60x60 mm. It should be noted that the first corner must be straightened from 90 ° to 60 °. If this is not done, then it will not work to fix the manufactured structure on the grinder. After the metal corners are installed, the tool itself will need to be fixed on them. It is connected to the structure with a separate handle on one side, and on the other with a bolt and nut. The latter will be needed so that the screw does not unscrew from the structure in the process of cutting the material. You can not mount the nut on the handle, as it will be held by hand. At this stage, the design for cutting is made.

How to make a frame for a grinder with your own hands?
Such devices for angle grinders are used in order to be able to facilitate the efforts made by the user to work on cutting workpieces. It should be understood that holding a tool with a large weight in your hands for several hours is quite difficult. Therefore, most craftsmen want to make a special fixture for a grinder, which is called a bed. With the help of such structures, it is possible to carry out work on cutting metal blanks with one hand.
First of all, you need to make a box of wood. You can make only one side, so that it is possible to fix the grinder. All other walls must be removed, and special legs should be attached in their place.
However, for such a tool to be effective, the first step is to adapt it to existing conditions. To do this, you will need to dismantle the casing of the angle grinder for protection. Next, put a disc on the tool. When it is pressed against the side wall of the fixture, you need to make a mark where the gap was made for the stroke of the nozzle or disk. It should not be too wide, otherwise foreign elements may get inside the structure. However, it is worth knowing that the gap can be expanded. This should be done in cases where there is a need to replace nozzles without completely disassembling the entire structure. Several wooden bars can be used as supporting elements. After that, you can start sawing various workpieces.
A carbon grinder (angle grinder) can be one of the most useful and versatile machines if you get the most out of the tool. It is important not to forget how to use an angle grinder. Unlike a drill (rotation 700-1200 min -1), an angle grinder has a rotation speed of up to 12,000 rpm, so it is important to observe some basic precautions.
Features of using the grinder
Protective goggles, hard gloves, safety boots and a dust mask must be worn. Tile jigs are great for cutting straight across ceramic or stone tiles. However, you will find it difficult if not impossible to make accurate cuts for the workpiece around obstacles. Do-it-yourself devices for an old angle grinder easily cope with these complex tasks.
If you cut the bolt flush into concrete or other material. Firmly attach the long side of the rack, making sure it is in place. Part of the workpiece that will fall out after the cut can damage the legs.
With the right choice of disc, your angle grinder can be used to repair rough edges on many household tools, including lawnmower blades, shovels, hoes, and even axles. After that, you can always refine the finish with the windmill file.
It is advisable to use a grinder for work on removing peeling paint, dry cement or rust from metals. There are numerous wheel disks with a wire brush, they are all designed for various types stripping, cleaning and deburring. Before making a purchase, check the manufacturer's description.
If you have a lot of grout to remove and the hammer and chisel just won't remove it, a grinder might be the way to go. Using an angle tool to remove the old mortar will result in a lot of dust. Dust mask required.
The technology of work with the device is designed to work with various materials to achieve a variety of finishes and effects. By choosing the right cutting wheel, you can complete an even greater variety of household tasks, including polishing, buffering, sanding, rounding and shaping. Do-it-yourself attachments for a grinder can significantly expand the forms of application.
Materials and fixtures to make nozzles for grinders
Wheels and disks angular grinding machine can be made from a number of materials. However, in the general case diamond disc will provide maximum precision and polish. Wheels are available in a range of abrasion (or grit) levels. Use a higher abrasion accessory for rougher polishing surfaces.
However, despite all this, many people still decide to create components for the Bulgarians with their own hands. If you decide to create fixtures for a working angle grinder yourself, then before starting work you need to prepare the necessary tools:
- An electric drill, preferably.
- Set of drills.
- Discs must be selected with a diameter of 125 mm.
- Wooden blanks.
- Metal corner.
- Steel plate.
- Self-tapping screws.
When it is necessary to use the grinder for specific tasks, in this case, many masters opt for ready-made applications. They can be bought without problems in the construction supermarket. The devices are not very expensive.
Rack for grinder
No matter how skilled a craftsman is, they need the perfect tools to get the job done. The angle grinder stand is provided as an excellent tool for perfecting these corner pieces.
The grinder stand allows you to grind at perfect angles of 115 mm-125 mm. If the rack is aluminum alloy, this allows you to have a fixture that will undoubtedly last a long time.
Get more out of your corner grinder with a convenient holder. Angle grinders are dangerous tools. Homemade grinder tools will allow you to have more control over them, but still we must use everything necessary funds protection such as goggles and gloves.
What you need:
- Devices for woodworking.
- Piece of hard plywood 300×100×20 mm.
- A piece of hard plywood 150x100x20mm.
- 1 x M12 screw, 30mm long.
- 2 washers M12.
The design is very simple, it is only necessary to form a part 150X100X20, adapt it to the shape of the grinder.
There is a fixture and simple drawings for a grinder that can be created by hand. The grinder stand is very useful in the metalworking workshop, as well as in woodworking.
Used parts:
- Metal base plate.
- 3 "C- section section angle 2 pcs.
- 1 "L- section section angle 4 pcs.
- Door bracket.
- Rigid spring.
- Nuts and bolts.
- Hardware.
How to do:
- Step 1: Create the stand base. The first step in creating a cutting machine with your own hands is its base. The whole 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 better job stand. First of all, you need to cut the L-section into four parts equal to the four sides of the base plate. Then glue the base plate and the L-section together. Make sure the seam is perfect and precise.
- Step 2: C- section to hold the angle grinder. The holding capacity of the C-section channel is very high. A piece of metal is welded to this C-section to hold the angle grinder with a bolt or angle grinder handle.
- Step 3: - Another part of the C-section. Welded metal detail at the end of the C section.
- Step 4: - Attaching both parts of the C-section.
- The door bracket is used to fix both parts of the C-section.
- Step 5: - Attach the springs and the entire assembly. Now this whole assembly is attached to the base with two bolts. Then attach the spring.
- Step 6: - Hold the workpiece.
This is the last step in making an angle grinder. You can use a long bolt and an L-section channel to make a workpiece holder. Two hex bolts are used to attach the L-section channel to the base.
A wall chaser from a grinder allows you to do do-it-yourself tracing for everything Construction Materials in absolute safety, and in the absence of dust. This is a fixture for wall mount very useful if you need to make cuts for piping installation, place cables for electrical systems and for the installation of pipes for hydraulic systems.
The saw blade fixed 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 getting them personally when sawing.
Depending on the properties of the material and density, it is recommended to choose the engine power for a wall chaser from a grinder with your own hands. A modest block is enough for a cable furrow. For a long groove for a pipe, 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 around 6200 rpm, which guarantees the ability to cope with industrial scale.
But the design of the grinder is such that it cannot be used due to active education dust. Often they resort to upgrading the device.
You can design a device with two disks. Installing a machine from a suitable grinder with your own hands of this type will cost more. The first drive is attached as usual and the second one is mounted. A second nut is needed, which has an additional ring, for fixing. When working on the wall, the sander must be in the protective cover.

Since any angle grinder is equipped with powerful engine with a gearbox - you can make a stationary milling cutter from it. 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 shaft of the grinder is brought out into the hole of the workbench, a cartridge for milling heads is put on it - and not too hard woods can be processed.
- Step 1: Create the angle grinder bracket. You can use the threaded holes in the grinders as reference points for the bracket. There are many ways to approach making a handle, depending on the type of grinder you choose to work with. Critical measurements needed for layout functional design, which makes it easy to separate the grinder for self made. 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 a wooden handle.
- Step 2: Create a clamp that will firmly hold the handle of the grinding head against the head of the adjusting bolt.
- Step 3: You then need to attach a leg to the front end of the rods to secure the angle grinder bracket by turning on the hinge function to allow the grinder to pivot towards the cutting table.
- Stage 4: Building the foundation. It is possible to use a simple frame by using tubes and mounting them with two pieces of iron. It is necessary to form a flat platform for mounting the slider mechanism.
- Stage 5: Assembly.
- Step 6: Adding a cutting table. The cutting table consists of a steel plate. After all parts are assembled and adjusted, align vertical surface cutting wheel.
- Stage 7: Final testing.
Clamp for grinder
Create wooden box. You will need a base for this model. You can use wood and use liquid nails. But you can use plastic, metal or wooden box.
Check if the angle grinder is suitable
Make sure the grinder's fuse doesn't trip when you attach the grinder and make sure the fuse is flush with the box. Attach the grinder and check the work.

How to do:
- Step 1: Create the stand base.
- Step 2: Material preparation
- 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 beam 40 × 30 × 3 mm;
- Mark the center and drill a 10mm hole on one side. The hole should have a diameter of 7 mm;
- Cut two pieces of iron 150 mm;
- These blanks require 3 holes. The hole must be located 10 mm from the edge;
- The holes must match the bolts;
- Shaping the rods is necessary in accordance with the grinder to match the profile of the machine;
- Cut off one piece of 30mm iron rod. Drill a hole with a diameter of 7 mm.
- 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 iron rod 30 mm from the side.
At this stage, it is important that the final part is at a right angle.
- Step 4: Base
- Take 2 pieces of 40x30x3mm iron bar and place them on the sides on both sides and change the screw to connect them 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 fixture elements (give only one soldering point) on both sides. Make the necessary adjustments. There should be no excessive displacements.
- To facilitate movement, two washers are intelligently installed between the side and the handles.
- Step 5: Completing the Assembly
- Watch to see if you are moving freely, and the angle can reach -90º.
- After checking alignment, perform final welding.
- Step 6: Processing the base. Mark the cut. Start by gluing the corners and finishing with a saw.
- Step 7: Base with sander installed. Take advantage of the handle support that already accompanies the equipment and replace the original screw.
- Step 8: Screw Depth Hole. The screw allows you to adjust the depth of the cut. Pay attention to the alignment of the disc in the longitudinal and transverse directions.
- Step 9: Reminder. Remember that this instruction is for a grinder with three factory holes. This made it possible to fix the machine in the support, and the third hole regulates the cutting depth during operation.
Sawing device for porcelain stoneware
By tilting the fixture, expensive material can be easily inspected. 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.
Such a technique requires the installation of several guides on the platform, followed by movement along the intended trajectory. Also, a homemade fixture will allow you to change the angle of cut and the depth of processing. To create a machine for porcelain stoneware, you will need proven drawings and work experience.
How to make a frame for a grinder
The grinder can be used for grinding or cutting when changing the necessary nozzles, according to the principle of operation circular saw. Thus, it is possible to process pipes and workpieces even with large diameters. flat corner sections.
To create a bed, you need:
- Bulgarian.
- Drill.
- Welding fixture.
- Steel plate.
- Steel plate 3 mm thick.
- 40×40×5 mm square tube.
- L-profile 30×30×3.
- 80mm screw, nut, two screws, spring washers.
- Step 1. You need to cut off the details right size and clean the ribs from chips and irregularities.
- Step 2: Easy fastening for 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 strong enough that no additional connections are needed. To connect the new module, factory threaded grooves from the grinder are used. Before welding, simply install these plates and screw (to disassemble the joint if necessary) using an angle grinder. Hold cutting disc in place and use a right angle for the lining. - Step 3: Make an additional position for the handles.
A hole has been made, large enough for the handle threads to fit securely into the slots (10mm). Cut off the handle needed for the shape base and fasten the nut to the drilled hole.
Next, you need to weld the elements. Place and shape it so that you can still press the Disk Lock button. So you can change new disk without having to uninstall your application. - Step 4: Create the bottom plate.
It is necessary to create 8mm holes for the “rear stop”, this is the part of the 30x15mm L-profile mentioned earlier. Connected to it by butt welds. This way the bottom plate stays straight and the result looks better.
- Step 5: Connecting to the bottom.
Connect these two parts of the metal module together.
You can use a simple "hinge" from a piece of 40x40x5mm square tubing.
Drilled hole 12 mm diameter to the center of the side, through both surfaces. The product is welded. - Step 6. The material is pushed off the "hindfoot" so that the angle grinder is suitable for moving lower vertically. Welds need to be cleaned with a steel brush and finally painted in the desired color.
Tripod for angle grinder
The personal angle grinder attachment turns the angle grinder into a versatile and precise cutting attachment for steel, metals, profiles, pipes and rods. This block has versatile applications and is suitable for most common angle grinders. Retainer for the grinder received various forms execution. It is necessary to create universal adjustable mounting brackets for an angle grinder. Provide protection against metal sparks.
Protractor for grinder
When working with metal profile or important details requiring even seams, it is effective to use a protractor for a grinder. Using the device allows even an inexperienced person to create a cut exactly with a given slope. The protractor is irreplaceable during the work with a ceramic tile and a plinth. If desired, they often create a homemade protractor for homework with a grinder.
To begin with, the installation of the guide corner is carried out, equipped with a special pad on flat surface(ceramic tile). This is done 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 disk.
In the design of a do-it-yourself protractor, three main components can be distinguished:
- corners.
- Loops.
- Pain to fix.
The principle of operation of the protractor is to install a special guide corner with an overlay on the processing workpiece. Creating an accurate protractor is a rather laborious process.
Bench grinder for grinder
Required fixtures and materials:
- grinding device with an 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 sorted drills;
- reciprocating saw or coping saw;
- optional but highly recommended.
- Step 1: Design. This model is designed for a cheap grinder. Think through all the details.
- Step 2. Getting started. You will need a base and some support to get your grinder high enough to clear the wheel. Processing can be done with a hand saw.
- Step 3: Support. Mark and cut out the 2 side supports, then forward and secure them with screws, pre-drill them (dimensions may vary).
- Step 4: Drill and fasten. Next, you need a bolt that fits into the hole for the handle of your angle grinder.
- Step 5: Fixture Restoration. Now you need 2 sides. Where the scrapers will make the circuit stronger, but if you don't have a fixture, it will work without them.
- Step 6 A tongue is a depression or groove in the edge of a piece of work material for attaching another board. There are several ways to add them. The easiest of them will be with a table saw, but if it is not available, another way is possible. Method 1. Mark where you want to get the tongue, pinch a piece and use a saw to cut gently on the side of the line. If you want to make it easier, you can take a piece of wood and place it on the side of your line to make a barrier. You can keep making cuts along the side until you reach the end, and then cut out what's 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 mount your 2 sides and measure the dimensions of the top of the product, cut out the required cover and install.
- Step 9: Strap. One bolt is not enough to hold an angle grinder. The bolt is subjected to flow on it, so find some strapping material, adhesive tape. Such products will work if you have absolutely nothing. You can use a small strip of metal.
The capabilities of the grinder can be expanded not only through various nozzles, but also by installing it on special home-made devices. As a result, you can get a cutting machine, with which it becomes possible to accurately cut metal blanks at any angle. In addition, the grinder can be installed on a carriage, and the resulting machine can be used for cutting sheet steel.
In order to understand how to make a cutting machine out of an angle grinder (angle grinder), you can look at various drawings on the Internet. But they will not help much, since all the dimensions of the parts will still have to be selected based on the size of the grinder you have. Options for the execution of devices can be both simple and more complex, requiring the ability to handle a welding machine.
Option 1
To make this device for the grinder, you will need welder skills. So, you need to do the following.
First, cut 2 small pieces from the corner (50x50 mm). Their size is selected based on the dimensions of the gearbox block of your angle grinder.
Next, drill holes in them with a diameter of 14 mm and screw the corners to the angle grinder, as shown in the next photo. If you do not have suitable bolts, then you can use threaded studs M14. Just be careful that the bolts are not too long. Otherwise, in some models of angle grinders, they can cling to the impeller located in the gearbox housing.
Without removing the corners from the grinder, grab them by welding. After that, the corners can be removed and scalded well.
Clean the welds with a grinder grinder.
Then you need to make rotating arm support to which the machine will be attached. To do this, select 2 pipes of such diameters so that one can without special efforts enter another.
For a more accurate cut, masking tape can be glued to the tubes and draw a line on it.
Then, turning the tube, carefully cut it with an angle grinder. A piece of pipe of a smaller diameter should be shorter by 20 mm (thickness of 2 bearings) - it will serve as a spacer.
Choose 2 bearings suitable for its inner diameter for a thicker pipe. After that, insert a thin tube into a thick one and press the bearings on both sides.
Then insert the stud into the bearings. Be sure to put a washer in front of the nut.
When the swivel mechanism is ready, you need to weld a small piece of the corner to it.
The next step is to rack for rotary mechanism from the same corner 50x50 mm. To make the segments the same length, the corners can be pulled together with a clamp and cut off.
Also, without unwinding the clamp, they can be drilled immediately.
Attach corners with drilled holes to the ready-made swivel block using nuts.
Weld a longer corner to this rack, as shown in following photos.
Now you need to decide on lever length, on which the angle grinder will be fixed. This is done by selection, based on the dimensions of your grinder. You can lay out the details on the table and calculate the approximate dimensions of the lever, which is best made from 2 square segments profile pipe 20x20 mm.
Pipes must also be clamped with a clamp and cut to the same size.
After all the parts are ready, they can be welded together, as shown in the following photos.
At the next stage, you can attach the angle grinder to the finished structure and check again what came of it.
The ready-made pendulum mechanism for the grinder is easy to install on any flat surface, for example, on the workbench. Also this design can be installed on a table specially made for her. For a more rigid fastening of the mechanism, small pieces of corners can be welded on both sides of the long corner, and holes drilled in them.
In the following photos you can see how it is fixed on the table (in this case, a metal frame is used) finished fixture for USM.
It is very important to set a right angle between the plane cutting disc and the plane of the table. Put the square on the table and move it to the abrasive wheel mounted on the angle grinder. If initially you managed to weld the fixture so that the angle between the planes was 90 degrees, then that's good. If you notice a deviation from right angle in one direction or another, then you can correct the situation with a crowbar or a long profile pipe, for example, 60x20 mm.
To prevent the part from moving when cutting, a corner can be screwed onto the table, which will serve as an emphasis. Also, for an accurate cut, the table can be easily improved with a simple vice made of a nut welded to it and a stud of the required length screwed into it.
Next, you need make a protective cover. It is done taking into account the maximum diameter of the cutting disc, which is permissible to put on a specific model of angle grinder. To make it easier to determine the dimensions of the casing and places for attaching it, you can first make a template, for example, from a piece of cardboard.
In this case, the casing will also serve as a limiter for cutting tool, which does not allow him to go too deep into the table during the processing of the part.
It will not be superfluous if for a lever with a grinder attached to it make a spring. In this case, it is easy to do this: paste with reverse side rods a smaller tube and attach a spring to it, as shown in the following photo.
On this, the manufacture of a cutting machine with your own hands, in which an angle grinder is used as a drive, can be considered complete.
Option 2
Another version of the fixture for the grinder, with which it will be possible to cut metal blanks, is done as follows.
Thus, a simple cutting machine was obtained. To give additional rigidity to the attachment of the device to the lever, you can use clamps, after laying a wooden block between the angle grinder body and the pipe, for example.
For precise cutting, so that the workpiece does not move, you will need to screw the corner to the table.
For a little grinder a similar version of the device is also suitable, only the angle grinder will be attached to a metal strip: on the one hand, with a bolt to the angle grinder itself, and on the other, with a clamp.
For a powerful angle grinder the device is made according to the same principle, but from profiles bigger size than in the figures above.
It is not necessary to use dumbbells as a counterweight. All you have to do is find the right spring.
Option 3
This fixture option is the simplest for making your own. It is made without a traditional stand (rack) for a rotary unit. All you need is one door canopy, a metal strip and a rubber band (you can use a rubber band from a hand expander).
The construction is done as follows:
- in the metal strip, on one side, drill holes for the door canopy, and on the other, for the bolt with which the strip will be attached to the grinder;
- screw the angle grinder and the canopy to the strip;
- screw the canopy to the table;
- fasten one end of the elastic to the edge of the table, and the other to the holder (handle) of the angle grinder.
In just a few minutes you will receive a high-quality cutting machine. This device is also mobile, because it can be carried with you in a tool case, and, if necessary, mounted on any flat surface.
When installing this fixture, do not forget to fix a corner on the table to rest the workpiece in it.
Cutting sheet hoist with angle grinder
For cutting sheet metal need to purchase special carriage, which moves along the guide (profile square pipe).
But as practice shows, the cost of a good carriage is high (more than $ 100), so you can make it yourself. Because the this process quite difficult to describe, you can understand the manufacturing technology of this slider from this video. With the help of the device, you can cut not only steel, but also ceramic tiles, and porcelain stoneware.
Please note that when cutting ceramics, a lot of dust is generated. Therefore, it is recommended to adapt a dust collector with a nozzle for a vacuum cleaner to the casing of the angle grinder.
How to make a homemade dust collector
The simplest dust collector for angle grinders can be made from plastic bottle from engine oil.
The nozzle is made as follows.
After these simple steps, you can use the grinder to process materials, the cutting of which creates a lot of dust.
