One of the guys in my turning club is a metalurgist … he advises against dipping HSS tools in water (‘quenching’) to cool them. He says it can cause micro-cracks, resulting in chipping and cracking.

An 8” slow speed grinder with a 46 grit Norton wheel can take a lot of steel off without generating much heat. My WoodCraft grinder has a 46 grit wheel for grinding a new bevel and an 80 grit for touching up a working edge.

@lumberjoe—Do you have a tool rest for your grinder? To sharpen scrapers, skews, and parting tools, all you really need is a tool rest that has an adjustable platform. If you don’t have one, Grizzly has one (G8987 Optional Heavy-Duty Tool Rest) for about $20.
