I need a spindle sleeve for a recnetly purchased South Bend Heavy 10" lathe. Are they available at a reasonable price? I would like to use a MT #2 dead center with the sleeve. What is the taper of these lathe spindles? My spindle has a 2 1/4 x 8 thread.

Others may correct me on this. I think the Heavy 10 has a Morse 4 1/2 short taper, which is an oddball, although I may be remembering incorrectly.

Your best bet may be to try the Usual Suspects list of used machinery dealers who advertise in Home Shop Machinist (Plaza Machinery, Dave Sobel, etc.)

Miller Machine & Fabrication has the adapters, made new as well as many other repair parts for American lathes.

I have no connection with them, but they are a good source for these parts.

The spindle taper could be propritary also. Though not a heavy 10, I have a 9 1/2" floor model South Bend with the 2 1/4-8 spindle thread with a propriatary internal taper. I was able to find this out by calling South Bend directly with the both the model and serial numbers from the lathe. I was able to buy an adapter at a reasonable price some time (15?) years ago direct from South Bend Lathe. I do not know if that is still possible. I beleive, could be wrong though, they were bought out, though I can't remember by whom.

I'm pretty sure that Clausing still sells MT4-1/2 to MT3 spindle adapters. At least they did a couple of years ago and got around $50 for them then.

this is all good info but what steal do you use? does it need to be heat treated?

If I wuz making one, I'd probably use 1144 "Stressproof." It machines well and is strong.

For home shop use I wouldn't bother with hardening...just use reasonable care in use. If you harden it, you'll need to grind it, and that gets too complicated for what I can do in my shop.
