I purchased a supermax 1338 about a year ago, I paid more than i should but I was excited and was being stupid. This particular lathe was built in 1988, when I got it home the lathe wouldn’t go into forward and it had a bent pinion gear in the apron. Luckily the guy who sold me the lathe had another supermax and I swapped the apron. Prior to this I had a 10 inch Southbend so I had little to no machining experience. A part of me is glad this all happened as it forced me to learn and get out of my comfort zone. The first thing I did was realize the person who sold me the lathe installed a non reversing contacter which is why it wouldn’t go into reverse, so I installed one and upgraded the transformer. That’s when I realized the hinged roller switches were bad , so those were replaced. That’s when I tackled the apron, I found a similar 13 tooth pinion gear and machined it to fit, machined a grizzly crossslide to fit , lead 1/2 nut , cross feed nut and screw and worm gear Lastly, replacing the tailstock Acme flange nut. For those of you who have a supermax or similar ....
7/8-8 acme 1/2 nut
5/8-8 acme cross feed
5/8-10- tailstock nut
Cross slide from 14 inch grizzly will fit with some machining, The worm gear setup also fits. This is all from the G0824 lathe
