Gene - IF you use quick change holders and tool post, once you have manually set tools, and don't remove them from the holders, you can touch off using the tool post body or a probe in a holder. As long as you clean the clamping surfaces good quality ones are remarkably repeatable. The downside is the price of holders, but I'll bet you'll need less than you thought you would (or bought ;) Steve Blackmore -- ------------------------------------------------------------------------------ Precog is a next-generation analytics platform capable of advanced analytics on semi-structured data.
