I don't know if they are technically suprior or inferior to other systems, but they are readily available (from RS and other UK supliers) and I have a pully hob so can make my own pulleys. Here is a rather special one I made for a rotating ball-nut arrangement. (that's the ball nut in the middle). https://photos.app.goo.gl/1dJiuUVVdZmrghI93 It was for the X axis of my mill, which is why the hob feed rate was uneven and too fast. -- atp "A motorcycle is a bicycle with a pandemonium attachment and is designed for the especial use of mechanical geniuses, daredevils and lunatics." — George Fitch, Atlanta Constitution Newspaper, 1916 ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
