How to increase the functionality of a grinder with a removable snap

The versatility of angle grinders or grinders can be judged by at least the most popular equipment for it - discs that are divided into cutting (abrasive and diamond), peeling (cord brushes), cleaning, grinding (with a thickness of 6 mm or more), grinding and polishing. Also, the variety of work performed by this tool is facilitated by the location of the engine and tool axes at an angle of 90 degrees with respect to each other.

The scope of this grinder can be further expanded, as well as increase productivity and efficiency with the help of a removable tooling, made independently, if you make some effort and effort. And we can do with ordinary materials and simple tools.

Will need

In addition to the grinder, which we are going to improve, we will need:

  • drilling machine;

  • mini drill;

  • plate bending machine;

  • welding equipment;

  • spanners;

  • measuring tool.

From the materials we will need:

  • sheet metal 2 mm thick;

  • steel ravnopolochny corner;

  • profile square pipe;

  • hex head bolt;

  • studs, nuts, washers;

  • spray can of black paint.

The technology of manufacturing removable equipment

Using a grinder, we cut off workpieces of the required size from sheet metal or a strip, as well as a steel corner.

We process and round all the edges and corners of the workpieces using a grinding wheel. We make markings and make holes of the desired diameter in the workpieces on a drilling machine.

We screw pre-prepared studs into the holes with thread on the sides of the grinder.

With the help of a mini-drill with a finger mill fixed on the table, we remove the chamfers in the holes of the workpieces. We fix two plates on the grinder using studs and nuts. A bolt with a round head for a hexagon and a thread for a nut will be welded at the point of convergence of the plates.

On a bending machine we make flanging at 30 degrees from the narrow side of a large billet of sheet metal.

From a narrow strip of metal according to the marking, we cut out an element in the form of an equilateral trapezoid with a cutting disc and in the middle we make a hole on the drilling machine.

In this and other holes in the workpieces, we chamfer using a finger mill mounted on the shaft of a mini-drill.

We insert the shank of the grinder handle into the hole of the element in the form of an equilateral trapezoid and on the other side of the plate we wind and tighten the nut, which is then welded to the plate.

In a square profile pipe, we drill a through hole through two opposite sides. We also drill on one shelf of a steel corner along the edges of the hole.

We cut off the element with the previously drilled hole from the profile square pipe with a grinder.

We install strips with holes on the studs and fix them with nuts. We check the convergence of the plates with a rectangular angle, in the vertical and horizontal plane, loosening or tightening the nuts on the studs. After that, the nuts are finally tightened.

The nut screwed onto the thread of the grinder handle is welded to the plate in the form of an equilateral trapezoid.

We put the trapezoid plate with the welded nut on the converging plates fixed on the grinder, and weld it in the place where it coincides in plan with the lower plates.

We weld a bolt with a round head to the place of convergence of the plates on the grinder, and the head should be located on the side of the disc on the grinder.

We remove the converging plates from the grinder and finally weld the bolt to them. We grind all welding joints with a grinding disc.

On a bolt welded to converging plates, using holes, install a fragment of the profile pipe and tighten it with a nut.

We put the equipment with the grinder on the flanging plate. Moreover, the fragment of the profile pipe should on one side coincide with the length of the side of the plate, and the other abut against the base of the flanging.

In this position, we weld a fragment of the profile pipe to the plate, before making sure that its sides are perpendicular to the side of the base plate.

To make it convenient to cook, we remove the equipment with the grinder, leaving only a fragment of a square pipe on the plate.

After its final installation, we weld closer to the other edge of the plate a steel corner with holes and the same length as the width of the plate.

Cut the outer half of the vertical flange of the corner with a grinder. We clean all seams and processing points with a grinding wheel.

We paint the welded knots with the black paint of their spray can. We assemble all parts of the equipment on the grinder with the help of studs, nuts and bolts.

We control the distance from the disk to the edge of the slider plate. It should be the same everywhere.

A grinder mounted on a slider can make movements around the bolt in a vertical plane, like a pendulum saw blade.

Possibilities of a grinder with a snap

Now angle grinders with such a tooling can quickly and accurately cut sheet metal, cut rectangular fragments, clean the edges, cut narrow strips along the guide from a long sheet with high precision, cut pipe and strip material, round corners on workpieces, replacing the cutting disc with a grinding one, clean blanks from rust, give them a salable appearance, etc.
