The last thing I got done was the spindle itself. A little challenging as it's 2.5" long, with a through hole of 3/32". The spindle is made out of 5/16 CRS. It turned out great so far. Every thing fits very nicely and turns smoothly and the through hole is on the money. I still need to put the radius on the pulley belt positions, and put a taper in the end of the spindle for the dead center.

Hey Tony,
Do you feel like another project for me? I don't have any way to make this worm gear at the moment. I can't single point standard threads right now. My lathe has a metric lead screw and the only way I know of to make this is by single point threading.

All I did today is the first stage of making the 4 jaw chuck.

Steven, here is the test cut. I didn't put a center in the part so the final cut should have less chatter. I can drill and ream the 1/8" hole but have no way currently to put the key slot in. I may have a 1/32" cutoff blade that could be fashioned into a tool.
