Duh... So I did. Need a hot wet washrag for the egg on my face... And I didn't follow thru, using a normal roller tipped switch instead because I had it, and the cam was the corner of a plastic box laying on the table saw. Didn't have the opto stuff on hand. Observing it now, the initial stop when its doing 120 degrees a sec, is right on the peak of the cam, probably a good 2 degrees past the switch click, then it creeps backwards till it opens, then a quick growp and its at the ini files stated offset showing 0.0000 in the dro. Seems repeatable, so I quit screwing with it. I do need to fiddle with that offset though, so that a lathe tool caught in the 3 jaw is pointing straight up. Then a precise grind is a piece of cake. :) Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
