1.25mm half-pitch. Pythagoras suggests sqrt(8^2 + 1.25^2) = 8.097mm. But as you are measuring rangent to the circular grooves I can believe 8.12. > I'll literally sand it off with a large dremel diamond wheel, which will > do it without any heat to speak of at 2500 revs, a job I can start & check > on the progress of tomorrow. :) I have always avoided losing the balls from ballnuts, but as far as I can see it isn't horribly difficult to re-ball them (depending on the design). Perhaps you could face-off the flats in a 4-jaw chuck on the lathe using a carbide or CBN tool? -- atp If you can't fix it, you don't own it. http://www.ifixit.com/Manifesto ------------------------------------------------------------------------------ "Accelerate Dev Cycles with Automated Cross-Browser Testing - For FREE Instantly run your Selenium tests across 300+ browser/OS combos.
