Got my first shot on the CNC milling machining center. Removed the vise, cleaned the table, cleaned the bottom of the vise. Reinstalled the vise and installed the indicator. Trued the vise in 0 to 0 both ends. Locked it down and checked both ends again. 0 to 0 both ends. When the vise was removed it was set down on a table flat. Flipped the vise over on itís side and cleaned the bottom with my hand. Barry, why do that. Vises are never set on their bottom mating surface. Gotta keep it clean and undamaged. Iím still behind on remembering codes and running a program. My mind/brain ainít what it was.
