I have some red threadlocker that must be 5 years old, still worked the last time I opened it a couple months back. Red is for stuff you might want to dis with an air wrench, green is a much thinner stuff that penetrates the smallest cracks. For the X bearing shaft, I needed one of the three special nuts I made, at 50 tpi because they will adjust the endplay preload, sealed solid because the next nut is a tapered nut, squeezing the fingers on the end of the shaft down onto the end of the ball screw, giveing a grip that may as well be welded. That threadlockered nut is where the anchoring wrench will hold the shaft while I tighten the tapered nut. I've done this 2x before, when I put ball screws in the micro-mill. That has worked very well for several years. > ---------------------------------------------------------------------- >-------- _______________________________________________ > Emc-users mailing list > Emc-users@lists.sourceforge.net > https://lists.sourceforge.net/lists/listinfo/emc-users
