Make your own... Should be able to do everything on a lathe and finish the outside surface with an angle grinder (if you don't have a mill).Need the subject part as mine is worn and broken.

LeBlond says they do not have information on the lathe, based on an image sent to them, so getting parts will be difficult, not being able to specify the part number. Additionally, I do not look forward to paying an exorbitant price for the part. The nut and rod are left-hand thread. Rod will be easier to get as a stock item from an after market dealer, but the nut is the hard part. I may decide to cut it myself. Thank you.
Iwananew10K's post had me scratching my head for a moment, as 8 thds/inch seemed initially like an odd number, as I tend to think of a micrometer dial reading in numbers like 0.200" per revolution. 10 tpi vs 8 tpi did get me thinking. My 13" LeBlond Roundhead Regal has the crossfeed micrometer dial graduated at 0.250" TOTAL cut per revolution of the screw. That being the case, ONE revolution of the crossfeed screw will actually move the crossfeed 0.125". 0.125" = 1/8", so the crossfeed screw on a 13" Roundhead Regal should be 8 threads per inch, Left Hand.
10 threads per inch will move the crossfeed in 0.100" per revolution of the screw, taking 0.200" as the actual cut. Using 10 threads/inch for a cross feed screw will mean the micrometer dial is going to be incorrect. Might work on a Southbend lathe, where, if I remember right, one revolution of the cross feed crank reads 0.200", or 0.100" "radially" or "off one side of the work".
Interesting little brain teaser, for sure.
I don't know what happened to my earlier reply so I'll repost it. My cross feed shaft and nut were also left hand thread. I mistakenly linked to the right hand versions available from McMaster.

They may seem expensive, but I've found they were well worth the money for both accuracy and ease of use. As a general statement almost all parts for any industrial quality machine are far more expensive than comparable parts for hobby machines. They are far more robust and will outlast those used in a hobby grade machine 10 to 1. They are used in machines expected to run 40 to 80 hours a week, 50 weeks a year, and last for decades.
I would venture to guess this is the first time the cross slide has been in need of repair in more than 65 years. Considering that a $150.00 repair seems inexpensive.
