I still haven't gotten pictures of what I have. The threads on this one are in REALLY BAD shape. In the wear area some of the threads are so badly eroded from rust that I am surprised that they will even feed at all. The two ends are quite different and different diameters, so swapping end for end could only be accomplished by cut/splice.
I'm not sure that the threaded rod I looked at from McMaster Carr will work for me. I'll need to get more information about the thread root diameter. On the rod I have, the thread root diameter is slightly smaller than what I would need to turn down to fit the left hand drive coupling...... again I would have to do a cut/splice.... not something I've done in the past.
I'm still working on a teardown of the carriage so I can see what else is needed, so I will get back to this in a day or two. So far the lead screw is the only major issue I've encountered.... mainly the lathe just needed a good cleaning, check and lube. Even the way's are even in pretty good shape, with barely detectable wear. Not bad for it's age..... timken bearings are marked 1945 and 1946.
Thanks to those that have offered suggestions. I now have something to work with and I'll post an update when I find a solution.
