The angle grinder stand is available in a variety of designs. A variety of materials and assemblies can be used for its manufacture. It makes no sense to recommend a specific design, since every owner of an angle grinder will adapt the angle grinder to their requirements.

As raw materials for the device, you can use profiled pipes, as the most durable and reliable for this type of work. For guides, you can use corners, channels 5U or 6.5U.

For complex structures, you will need a welding machine, but it is easier to get by with screw connections. If the work does not require special precision, then the angle grinder can be used simply as a portable tool.

To perform precise work, for example, with a grinding attachment, you may need a stationary device. a stand for an angle grinder, an angle grinder (you can assemble a simple collapsible machine with your own hands, which, after use, will be folded and hidden in the place designated for it). Such a frame is sometimes also made of wood. It is advisable to make a wooden bed if you do not expect frequent and prolonged use of an angle grinder.

Option 2

Another version of the device for an angle grinder, with which it will be possible to cut metal workpieces, is done as follows.

    Take 2 sections of profile pipe of the same height and weld them to a rectangle pre-cut from sheet metal.

Drill holes in 2 racks and in the lever (the length is selected experimentally), then fix the latter with a bolt, as shown in the photo below.

Attach a spring to the back of the lever.

At the intended attachment point of the angle grinder on the rod, drill a through hole.

You can now attach the angle grinder to the table.

Thus, we have a simple cut-off machine. To give additional rigidity to the attachment of the device to the lever, you can use clamps, having previously laid between the body of the angle grinder and the pipe, for example, a wooden block.

For accurate cutting, so that the workpiece does not move, you will need to screw the corner to the table.

For a small angle 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 adaptation is made according to the same principle, but from larger profiles than in the figures above.

It is not necessary to use dumbbells as a counterweight. It is enough to find a suitable spring.

Homemade machine made of angle grinder for cutting metal

Metal cutting machine made of an angle grinder: a detailed description of the manufacture with a photo.

An excellent machine for a home workshop, can be made from an angle grinder. Such a device allows you to quickly and accurately cut sheet metal of large sizes.

Homemade machine, is a mobile carriage with a fixed angle grinder, which moves along the guide.

For the manufacture of a cutting machine, you will need materials:

  • profile pipe 40 x 20 mm. 0.32 m;
  • profile pipe 20 x 20 mm. 1.38 m;
  • profile pipe 15 x 15 mm. 0.34 m;
  • strip 40 mm. 0.14 m;
  • strip 20 mm. 0.16 m;
  • bearings 100th series. 16 pcs.;
  • M10 bolts for a hexagon 75 mm. 8 pcs;
  • M10 nuts. 12 pcs;
  • washers 10 mm. 32 pcs;
  • long nuts М12. 3 pcs.;
  • long nut М10;
  • M12 bolt with full thread 200 mm;
  • bolts М10 40 mm. 2 pcs.;
  • hexagon bolt with full thread 70 mm;
  • caps for profile 20 x 20 mm. 6 pcs;
  • caps for profile 40 x 20 mm. 1 pc;
  • profile pipe 50 x 50 mm, for a guide. 2 m or more.

Further in the photo, the process of making homemade products is shown.

The first step is to make a roller carriage for the linear guide. As its basis, a profile pipe with a section of 20 x 20 mm will be used. You will need 4 blanks 300 mm long.

Then, in the blanks, you need to drill through holes for the future connection of parts. Their centers are located 25 mm from each edge of the shaped pipes. A drill with a diameter of 11 mm is required.

We turn the enlightened profile to the other side, and stepping back 50 mm, we drill similar through holes on each side.
To hide the bolts used later in the assembly of the carriage, through holes in the workpieces need to be completed. To do this, one wall of each profile must be reamed using a drill with a diameter of 17 mm. So all 16 holes are finalized, the remaining 16 adjacent to them remain intact.

We will make a shoulder for attaching an angle grinder, cut off a 40 x 20 mm profile, 300 mm long.

You will also need to make a knot to adjust the depth of passage when cutting. It is made from a 20 x 20 mm profile pipe, 160 mm long. Its ends are cut at an angle of 45 degrees.
From a profile pipe with a section of 15 x 15 mm, you need to cut small spacers 40 mm long. You will need 8 pcs in total.

Putting the structure together. An M12 bolt with a continuous thread, 200 mm long, will be used as the connecting hinge. 3 long M12 nuts are screwed onto it.
Having fastened the bolts and nuts with clamps to the table, you need to attach blanks from a pair of 20×20 mm profiles, and one 40 x 20 mm. Pipes need to be welded to nuts.

Then, from a strip 40 mm wide, you need to cut 2 blanks 50 mm long. In the center, closer to the edges, drill along the hole with an 11 mm drill.

These plates will serve as an attachment of the angle grinder to the standard holes used for attaching the handle. In some tools, these holes can be made for M8 bolts, which will need to be taken into account. For reliability, the 40 mm M10 clamping bolts must be equipped with nuts. The bolts are screwed into the gearbox through the plates and tightened with nuts.

Now, slightly stepping back from the fastening of the plates, a previously made workpiece from a 20×20 profile with a length of 160 mm is boiled down. On its free end, a plug is welded from the same strip as the mount for the angle grinder. A hole is drilled on the protruding ear of the plate, and an M10 nut is welded onto it. To strengthen the structure, additionally on the side of the profile, you need to weld a steel strip 160 mm long, also sawn at 45 degrees.

After painting the parts, we assemble the carriage. This requires M10 Allen screws, 75 mm long. It is necessary to pull the blanks of shaped pipes 20 x 20 mm together. At the same time, a pie is collected between them: washer, bearing, washer, spacer, washer, bearing, washer. Repeating this 7 more times, the result is a finished carriage.

Assembling the mount for the angle grinder.

On the table, install the guide and roller carriage. Its height is regulated by a lining of wooden blocks. The tool is attached to the edge of the table. The workpieces for cutting are pressed with a pair of locksmith clamps. For convenience, you can cut in several passes, each time adding the depth of the cut.
