Cross feed trapezoidal nut for Köpings S7C metal lathe from 1928.
Original part was missing, so I did some measurement and designed new one.
Made it with TR22x5 thread and extruded whole thread profile 0.65mm as i did not found TR20x5 automatic creation from software (not the whole 1mm as printed holes always seems to be smaller in my prints that they are in drawings). Good and snug fit, used some oil while installing it.
M8 bolt attachment on top of it, with 16.5mm diameter knob, 5mm height to fit stiffly to cross feed plate.
Tested, works. Havent tried to actually work with it, so cant say does it last long and how well it does handle pressure.
Just made it to get my lathe working as i was missing this part.
