Re: Case Hardening the Permanent Spindle #lathe

I don't think it needs to be hardened. If you just want to, that would be up to you. Be aware that hardening it will cause it to warp. Then you'd need to grind it. You essentially open several cans of worms that you don't need opened. Bill in OKC William R. Meyers, MSgt, USAF(Ret.) A human being should be able to change a diaper, plan an invasion, butcher a hog, conn a ship, design a building, write a sonnet, balance accounts, build a wall, set a bone, comfort the dying, take orders, give orders, cooperate, act alone, solve equations, analyze a new problem, pitch manure, program a computer, cook a tasty meal, fight efficiently, die gallantly. Specialization is for insects. LAZARUS LONG (Robert A. Heinlein)

Question for larger group:Should the headstock spindle be case hardened? Or even just slightly hardened?Today I 'finished' machining the headstock spindle and am wondering if it shouldn't be hardened in some way to protect it from regular use.
