I haven't worked on this lathe in a while... and I don't like not having it running...
I've started working on the Turner Uni-Drive gearbox, I plan to 'rebuild' it with new bearings and seals. Of course, I'll have to disassemble it and clean the gunk out of it also.
So I began the disassembly... and quickly found a problem with the gearbox. One of the shift forks is broken...
The chances of finding a replacement is zero... I'll have to repair this one. It is cast iron... I'm not confident in my ability to successfully weld it back together. I can braze it, but I'm not convinced brazing would really be strong enough.
I have about .300" clearance between this shift fork and the next one... I'm considering brazing this piece back together, blending the brazing flush, then machining a piece from 1/4" steel and 'plating' the outside of the shift fork to reinforce it. That (I think) would be strong enough... it would just be a lot of work.
Otherwise, the gearbox is in excellent condition inside... I haven't found any damage on the gears or shafts, it's just nasty inside (and outside).
