Funny you should say that, when making the ultra-thin glass specimens they had to be mounted in epoxy, held in a bit of 3mm brass tube (the sort of stuff that modelmakers use) sliced into 0.25mm discs. I was paranoid that if I muddled up the specimens I had no way to tell which was which, so found that I could relatively easily write reference numbers in the wall thickness of the brass tube without too much difficulty, as long as you used a microscope. Just goes to show that accurate optical feedback will make up for any amount of play and elasticity in the control system. -- atp ------------------------------------------------------------------------------ Crystal Reports - New Free Runtime and 30 Day Trial Check out the new simplified licensing option that enables unlimited royalty-free distribution of the report engine for externally facing server and web deployment. http://p.sf.net/sfu/businessobjects _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
