For a thread of that size (19,5 mm), make J about one quarter to one third of K, maybe even half in aluminum. One needs to take off enough material to get the tool below the surface. This should give five to three passes before any spring passes which I would not bother doing. Otherwise, I'd use a tool post grinder with many passes. -- Kirk Wallace http://www.wallacecompany.com/machine_shop/ http://www.wallacecompany.com/E45/ ------------------------------------------------------------------------------ "Accelerate Dev Cycles with Automated Cross-Browser Testing - For FREE Instantly run your Selenium tests across 300+ browser/OS combos.
