Don't overlook those antique malls for tools

Buddy had a 1.5HP 3 phase industrial grinder he liberated from a closed Aerospace plant, talk about torque! It had a magnetic relay power switch.....CLUNK! My generic 1/3 horse grinder is a joke, I have to chuck a grinding stone on one side for a flywheel to run a buffer wheel on the other to polish metal, but my 3/4hp HF buffer kicks ***. Old stuff is usually better than the new, I like old brass desk fans.

Sounds like a whopper. I have a buddy that scraps and comes across deals like that every now and then. Unless you pay big bucks for them older grinders are usually a lot better than new. This grinder I picked up is rated at 3/4 hp and it's all I can do to slow it down just a little with a piece of 1/4" steel baring down on it nearly as hard as I can. Last year I bought a 3/4 hp grinder at harbor freight and it was a joke. Would barely even sharpen a small lawn mower blade. Took it back and got my money back.
