I'm repairing a spare tailstock for my Studer RHU grinder, and need to make a new quill. Approximate dimensions are 32mm (1 1/4") diameter, 215mm (8.5") long, MT2 socket. I plan to rough turn it, rough turn the taper using the compound, finish the taper with an MT2 taper reamer, then put the quill onto my cylindrical grinder and touch up the OD.
What material you suggest for this? One choice would be 42CrMo4 (1.7225 or 4140 prehard). Or should I use another type of steel and take it to a hardening shop for nitriding or case hardening or carburising (after which I lap the MG2 socket and grind the OD)?
