This is a replacement part for a South bend lathe model 9C that I just received, this part was worn out so made a replacement out of ABS PLA may be stronger.
I made it in 2 halves and glued them together with ABS juice.
The lathe has a 3/4 8 TPI acme leadscrew, the chaser gear has 32 teeth.
I will have other pieces for this same lathe, change gears, cross slide nut, top slide handle,
Plus whatever I need to replace because it is missing or worn out.
My lathe was made between 1937 and 1940.
For those of you that may want to try and print the body in one piece, brian_groves has reworked the body to be one piece, so see the thing below
THE TWO HALVES WERE GLUED TOGETHER USING ABS JUICE THEN LEFT OVERNIGHT I RAN AN 8MM DRILL THROUGH THE HOLE THEN AN 8MM EXPANDING REAMER.
i USED 8MM ROD BUT YOU CAN USE 5/16
THE MOUNTING HOLE IS 3/8 INCHES AS PER SB9C LATHE
GRUB SCREWS A 5MM
