I just got off the phone with this guy and he said the other screw

indeed left hand thread! Rats... He used the contact addy using

I'm retired and tired.. of winter..

If not, standard threaded rod will get it back in service quickly,
with the same inconvenience as reading a lathe dial backwards when
boring, or you could redefine the directions of the axes on your
drawings; Y is normally reversed anyway. I've markered a diagonal
arrow next to the feed handles to relate the rotation to table motion.
