Review on Holulo Mechanical Manufacturing Woodworking Laboratory by John Murphy

I wanted this to sharpen on my lathe. My compressor is 150psi max. This grinder needs at least 90psi before it will even work. At 100psi I pushed it against a tree and it stopped spinning and just vibrated. I can stop him with my hand. I'll have to try and run it at 120psi but I don't expect it to get any better. I think it would be ok to use very fine grit with light pressure.
