Southbend 5C nose collet

[KBeitz]

Has anyone one seen anything like this before? It's a 5C collet holder with Southbend
1 1/2 x 8 threaded. I bought my sixth southbend #9 bench lathe and it came with tooling.
But I have never seen one of these. It screws right on the spindle of my lathes.

It appears to be shop made.

What holds the collet in?

What holds the collet in?

Drawbar through spindle. Don't know why title says Bridgeport if it goes on a SB?

Your right... It was a late night last night... Bridgeport should have never been there...
I fixed the error...

Now you should go back in and change "coller" to "collet" or "closer".

Must be some kinda special draw bar........5C draw bars are usually about 1- 3/8" in dia. Just wondering how you get that through a spindle that's less than an inch in dia?

I imagine that the draw bar uses the internal threading of the collet, then a much smaller DB to the end.

Would it be closed on the material by driving the collet using a spanner which fits the slits in the face of the collet ? Which means the body would have internal threads to fit the outer threads on the collet. It appears to be shop made for special use and I don’t see a clean taper internally at the face !

The internal threads of the collet are still over an inch.....the draw bar would have to be inserted first, then the collet. The draw bar would need a nut on the outboard end.
