Checking My Nuts

Bummer, time to start searching for parts.

That is a bummer Ed. You may be facing the same problem I ran into with my lathe tail stock.  Enco said the shaft was discontinued and no longer available. (Of course.)  I had the local experts in town http://www.roton.com/ scratching their heads for awhile when I walked in looking for a replacement length of shaft. Turns out my tail stock lead screw had a metric diameter but had a ANSI/ASME thread pitch. 

So I wound up going to a slightly larger ASME diameter shaft and nut and machined a new shaft.
