Home made grinder

[dtech]

I needed a heavy duty grinder that would not slow down when grinding pieces for welding or cleaning rust and scale off. It has a heavy old 1/2 HP electric motor. I purchased the arbor assembly from my hardware store.
The base is a flywheel from an old buzz saw welded to a 3" pipe.
I made it 20 years ago and have not had any problem with it.
