Bill in OKC too
Guess I'm going to have to check mine more carefully, too.

The Catalog #405 or Type 5 has a 1-3/8-8 spindle. That’s an early Workshop Lathe. There are people who would give an arm for that chuck. On Oct 15, 2021, at 3:55 PM, wmrmeyers@... wrote:
There are lathes with 1-3/8-8 spindles, and 1-7/8-8 spindles, too. Both would look close, but no cigar. I recent bought a (we thought) 1-1/2-8 threaded Jacobs chuck. Turns out to be 1-3/8", and no, it won't fit my 1-1/2-8 spindle. I tried! I had uses for it. Someday I'll make adapters for the various lathes here, but not this week.

I can't speak to your lathe, but neither of mine have ACME threads on the spindle nose. They are 60 degree V threads. I've seen people use Atlas accessories on a South Bend, and vice versa on the 1-1/2"-8TPI threads, too. Might want to look again real close. With a thread gauge in hand. Or someone may have ordered it with an ACME thread, or modified a spindle. Stranger things have happened.

The spindle nose is an Acme thread. The McMaster link shows 60 degreee V threads.
Can buy one of these, and make your own thread protector, if you like: https://www.mcmaster.com/nuts/thread-size~1-1-2-8/ Some minor modification to make it just what you want for popping the collet sleeve back out. I've mentioned that I'm a cheap bastrich, right? You could make your own, if you can cut 1-1/2-8 internal threads yourself, too. I can't yet, Couple more lessons in class to learn that. Anyone care to guess what I'm going to be making when I'm supposed to be working on the class project? Also need one for my SB Heavy 10L, with the 2-1/4-8tpi spindle nose. I have already made stub spindles for both machines so I don't have to go to the machine to test fit stuff I make for it. Bill in OKC William R. Meyers, MSgt, USAF(Ret.)
