The A2 rod I have bought isn't that straight, so one would have to average the rods gravity sag and UPS induced wibblies as its turned slow enough the indicators electronics could follow it. Not impossible but watching paint dry slow. I could salvage 3 7mm OD ball bearings from old Sony bvu-800 capstan rollers, and make a 3 point roller gripper for the rod to drive an indicator I bought to put on the tailstock barrel but never found my round tuit. It has a data output socket that could be recorded and analyzed. Its an idea that does seem worth investigating. With some creative mounting that could also measure vertical bed wear to determine if moglic is warranted. And I could make the 3 point gripper a lot easier than making a laser diode mount that was straight enough. Yes, I think that might be a faster, cheaper solution, as I can make that from the junkbox once I obtain a full 3' length piece of A2. What I have left is only a foot or so long. thanks Andy. -- Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
