Often, to work with an angle grinder, it is necessary to fix it firmly, special devices are made for this, but with them the tool will be at the level of a yew or surface of a workbench. When you need an adjustable bracket, you should make it yourself.
The easiest way to attach the structure with a homemade clamp, you can make it from the corner with a welded plate, or a piece of a small channel. So that the clamp does not vomit, you can make a couple of holes on the upper side of the workbench and tighten a couple of screws.
Next, a stud is welded to the clamp, on which the working platform is installed. The angle grinder is screwed onto the same thread from above. The whole structure is easily adjustable in height and can be deployed for convenience. If the stud seems flimsy, you can use a larger diameter, then you will need to come up with an adapter for threading the grinder.
