Interesting Kirk. Does that roller actually roll? If all that wear is on just the side we can see, it apparently wasn't rolling. Critical lubricant needed on the axle pins? I don't see any plain evidence of wear either on the pins or the socket where it lives. IMO there should be at least a polished mark/area on the axle & holder. OTOH, if its worn like a 3 or 4 tooth gear, I'd wonder if the passing teeth on the detent disk were a perfect mathematical fit, meaning 1 full turn of the roller, for either 3 or 4 teeth passing on the detent wheel. When making a new roller, I'd try to have its diameter 3.5 linear teeth or 4.5, so the wear would be more evenly distributed in the future. Having an even fit, it would not take a lot of wear to assure it remained sync locked. In any event, thats a huge amount of wear. Not a normal looking wear pattern at all. > I made a Glade VCP application for testing with a PC parallel port: > http://www.wallacecompany.com/machine_shop/fanuc_mpg/gvcpMPG/Screensho >t-gvcpMPG-1a.png > > http://www.wallacecompany.com/machine_shop/fanuc_mpg/gvcpMPG/ Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
