How to make a miter saw with a broach for an angle grinder from bicycle bushings

For quick and accurate cutting of metal workpieces, it is convenient to use a miter saw with a broach. Since this is not a cheap tool, you can simply make a special stand for installing an angle grinder on it. This device almost completely replaces the trimmer.

Materials:


  • front bicycle hubs – 2 pcs.;
  • profile pipe 20x40 mm;
  • strip 20 mm;
  • spring;
  • bolts.

Manufacturing process


From a profile pipe you need to weld the base of the machine in the form of a frame. Its width is arbitrary, and its length is around 450 mm.

One bushing is welded with eyes to the frame. A 230 mm pipe section is welded to its bolts. Similarly, you need to weld the second free bushing with another piece of pipe.

A piece of strip is welded to the eyes installed on the last bushing.The result should be a U-shaped bracket, which must be welded to the pipe on a fixed sleeve. This is done so that the arms can fold completely together.

An eyelet is cut out of the strip, which is screwed to the grinder into a hole for installing a removable handle. It will need to be welded to the lever so that the fixed angle grinder moves strictly parallel to the edges of the frame when pulled.
