I have been signed up to be notified when its available again for 7 or 8 years. > For the Mini Mill there's a belt conversion and there's metal gears > available for the mill and the 7x lathes. Metal, for the micro-mill? URL? Chris has metal change gears for the lathe, but I don't recall seeing any for the spindle internals on his site. Is my mouse not aimed correctly? I did find a site where some fellow made his own, but he put the tach so v-belt slippage could affect it. I layshaft idea seems to be a good one on that site, but I'd druther have 3 sets of matching timing pulleys using an 8 or 10mm belt that one could slide the drive forward to slacken, and move the belt to the next pair of timing pulleys up or down, then lever the motor and layshaft back to the rear to tension the timing belt. But I found the timing pulleys to be awful pricey. And because my bolt for the z drive is about 2" in front of the post, the motor will still need to be mounted off to the side. One of those projects that will get done as the time becomes available. Thanks Gregg. Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
