We have a LeBlond Regal 13C3 lathe that is a 196? model. Someone must have jammed the carriage during operation and broke something in the drive because it will not feed automatically now. The Feed Rod is turning but the carriage will not move when engaged. I see by looking underneath that the Feed Rod goes through a Pinion gear on the back of the carriage. I figure that maybe a key is broken inside the pinion. Do I need to remove the whole carriage by sliding it off the end of the machine, or is there an easier way to repair this ? Your expert opinion can probably save a whole lot of unnecessary work. Oh Yeah, My book shows that the Feed Rod is a splined rod with 6 grooves, but our machine has a smooth rod with a keyway cut the entire length. It also dosen't have the Safety clutch to prevent accidents from breaking something.
