I grind and polish concrete and do epoxy floors. I was sick of working on my knees for edges so I made these edge grinders. One has a 1/2 hp motor and the other has a 2 hp motor. They work awesome and I would never spend money on buying one of these from a company that makes them because of the fact these I can make for a lot cheaper and they work perfectly.
I spent about 250.00 making both grinders the most expensive part was the drive shaft which I had turned at a shop since I don't have a lathe. I didn't spend much because I already had the motors and the square tube for the frame and the casters. Also I sold a couple of them to get my money back.
