Nice...I can see a new flat belt in its future..many use a ribbed timing belt and run on the back side.

Thanks for the link on flat belts. Yea, i sure need to do something different than using the flat side of a "v-belt". But whoever put the jackshaft on didn't make any provision for loosening the belt tension to change pulleys. I can at least push the thick v-belt with my fingers from one pulley to the next to change speeds. I guess I need to figure out some thing better but I'm a bit stumped on making a belt tensioning/loosening mechanism.

Pete, did that toolpost come with your lathe, or did you add it?

I bought the QCTP from CDCO Machinery and I'm very happy with it. The lathe had a lantern type tool holder, but I just didn't like using it. I seemed to spend all my time fiddling around with the tool post, rather than actually making anything.

Nice machine there Pete, micrometer adjustable carriage stop and all. Show us the jackshaft setup and there will be plenty of belt tensioner ideas thrown at you.

Some pics of the jackshaft that doesn't have a tensioning mechanism. Don't laugh too hard at the hockey stick legs! They at least keep the lathe from acting like a unbalanced washing machine in the spin cycle. But, I do need a better overall solution.
I think the previous owner had the motor mount pivot at the connection to the lathe. So if you lifted the whole motor and jackshaft upwards it swung up and towards the operator to create enough slack to reposition the lathe belt. But very awkward to do and it vibrated really bad. Pete

Pete, it's pure blasphemy to see hockey sticks used in such a way. Pucks I can abide by for leveling, but sticks for machine tooling, come on.........
At least it looks like you did not have to cut them to length.
