This could be what I have. I didn't see it in the parts manual, but the spindle nose sticks down a few inches and has a threaded OD.
How does the Quick Switch Spindle adapter work?
The spindle nose seems to be attached to the cutting spindle, but I haven't been able to make sense of why the bore would only be 1/2", when NMTB 40 takes 5/8"-11 thread.
AND I haven't been able to make sense of wht the purpose of the threaded OD on the spindle nose was for, unless maybe there was a misplace spindle protector (but that seemed a little off, seeing as NMTB40 is specifically designed for use with a drawbar)

I'll bet, if you take off the collet closer, your spindle nose looks just like mine.
Mine came with a homemade drawbar and an NMTB toolholder in it.
You could fabricate a drawbar (assuming that your cutting spindle bore is 1/2" like mine, it's a little work-aroundey, but you gotta work with what you've got ), and exponentially increase the number of toolholders you can find that will work with your setup (unless the collet closer will hold them in place just the same, then never mind the drawbar)

I've posted this here before but it's worth doing again. It has some pretty good info on the Kwik-Switch and Erickson quick change toolholders--might help you to sort things out...

JRock1000,

Your spindle looks like it has a no. 10 brown & sharpe taper in it with some kind of adapter. That looks very familiar to the 9-J mill with no. 10 spindle taper that I'm familiar with. Got to be a draw bar on the other end of the spindle.

I don't have any frame of reference to compare to.
It doesn't seem like there's an adapter in it (ie: seam where it meets, or shoulder in the cutter spindle bore).
I know it's not a Devlieg nose, because there's no cam.
Another thing that I don't get, is the drawing of the drawbar in the parts manual. The 40 N.S. (and 30) both appear to have 2 different thread diameters, with a shoulder.
Again, I don't have the original drawbar to compare it to.
Thanks for the link LKeithR. That page is a great reference.
The nose matches up with NMTB40 (with one of the drive keys removed). that's as far as I can suss out.

I guess there is a draw bar after all. I just thought it would be closer to the top or sticking out of the top of the spindle.

Looks like it was used as an anchor in the ocean!

Holy cow! That's going to be a mess to get to. Let see, what did I do with those 8-point square drive sockets? I hope they fit in there???

My fist thought is a piece of square tube with the right inside diameter. Make the other end fit a 1/2 socket wrench.

Despite my best efforts there is some rust. Mainly in the hole as pictured and the mill table. No rust on the ways and everything still moves freely. It is stored in a open barn and it's been raining here about one time a week for a while.
