Fixing the Mini Lathe Saddle - Flattening the Ski Jump - Part 4

Video Description

Continuing to tune up the Chinese Mini Lathe, next job to look at is the lathe saddle. I have had a lot of problems with surface finish and the tool cutting on the outfeed. In this series we're working through the various problems with the lathe saddle as it came out of the factory and working out how to improve its accuracy and rigidity. In part 1 we looked at the problem, take some measurements and start to hand scrape the bearing surfaces of the saddle in order to start to bring it into truth. In part 2 we identified a problem with the alignment of the saddle bed ways which we need to sort out before we can move onto the actual gib strips. In part 3 we refined the saddle gibs themselves and started to re-assemble the lathe. Optimism for a swift conclusion of the problem was high, yet premature. Here in part 4 we're addressing a bend in the lathe bed and are once more taking to the hand scraper to fix the problems that came out of the factory. The fix applies to the following lathe models: CJ0618, Crenex 7"x14", Clarke CL300M, Warco Mini lathe, Sieg C2 and many other brands which are based off the Chinese mini lathe design. However the techniques could be applied to other makes, models and sizes of lathe and aren't limited to this particular model.
