Possibly so. The reason for the roller tipped lever here is so I can go on by it without any damage. Same swtch is used for z on my lathe, but x is a teeny teeny button that is mounted to trip about 5 thou before x hits a solid stop on the backaway motion. I paint brush or air hose the swarf from in front of it before I command a home, but haven't managed to damage it in at least 2 years now. Pay no attention to that faint knocking sound, it just my knuckles on my head. :) Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
