This angle grinder stand comes in separate parts - lots of parts to assemble. The instructions are incomplete - mostly just a few tiny pictures. At some point, however, all the parts connect to each other. As a result, you get a stand to which you can attach an angle grinder and use it as a miter saw. Brilliant! Here's my thought. You can get a pretty good 10 inch miter saw for about the same price as this stand (and you have to add the cost of your angle grinder too). Which works better - a 10" miter saw or a 4-1/2" angle grinder on this stand? Do not get me wrong. Once you have this assembled you will have something to use as a base for the angle grinder.
