Hi all,
I have finally acquired my first lathe, an Emco Unimat 3, which, though I understand is very very small, is exciting to me!
It arrived in a big polystyrene box, not particularly well secured with the hand wheels removed. After a quick clean up the cross slide lead screw works great, very smooth. However, after hours spent looking over the Carriage lead-screw I can't get it to operate properly.
Inital issue:
After screwing in the hand wheel (23) and Acorn Nut (24) it seems to pull the lead-screw into its bearing surface (22) causing enough drag to make it very very hard to turn clockwise (same direction as tightening the hand wheel to the lead-screw), and counter clockwise both the hand wheel and acorn nut un-thread themselves before the carriage moves.
I have since sorted that issue out, repeated applications of sewing machine oil and elbow grease seem to have smoothed it out alot. However, turning the hand-wheel clockwise is still very rough, and the carriage is 'jumping' along when moving towards the head-stock, moving 1mm for every turn of the hand-wheels, but all at once, as the lead-screw moves back and forth along it's axis. Are these issues linked?
I appreciate any help, I hope I am not being too dumb. :wall: :hDe:
