A rigid fixation of angle grinders is required for any type of work, but there is no time or ability to make complex structures, then this solution will suit you. For mounting the grinder, only a pair of plumbing clamps and two studs for fastening are needed.
To better keep the studs on the surface, you need to take a couple of sheets of laminate and fasten them together. Two holes are made in the material into which the plastic dowels are placed, into which the studs need to be screwed. Then, clamps are screwed to the threaded part of the studs on the same level.
The clamps need to be selected so large that they hold the angle grinder tightly in them. With this installation, the grinder can be clamped in different positions, which will provide the ability to work in almost all planes. The design of this mount allows you to install in clamps and other electrical appliances, suitable in size.
