Spare off something. Axle from like vehicle. Bolt axle backwards through wheel. Weld axle gear to plate for grinder. Place grinder on stand with axle gear. I did this so if I'm working at home the grinder is outside. I can just lift it of and carry in the garage. Also have a vise with same gear welded to it. Can just change them out. Vise is just used for sharpening blades mostly. Not very good for to much torque.
