Default Steel suggestion for draw bar requested.

That will work, they sell it by the foot which is much better than buying 6
feet of it, the majority of which I'll never use. I'll be single pointing
it, I have the bar and indexable insert for threading id's.


I changed the spindle in my 12x24" Clausing from 2-1/4x8
threaded to L-00. The L-00 is a bit longer, so I had to extend the
drawtube. I simply turned it from 12L14 (IIRC) to thread into the
existing drawtube and to accept the collet. The extension is Loctited
into the original drawtube, and has served me well for years now.


12L14 is fun to turn. We run a lot of 7/8 to 1 1/4 inch 12L14 where I work
on a Index G200 bar feeding twin turret, spindle / counter spindle machine
with an internal unloader system.

I would not buy a machine with a screw chuck spindle. I've used two of them
and hated them with a passion.


The lathe was a good lathe at a pretty good price on eBay
(auction closed Christmas eve, FWIW, so there were not many bidders).
But I agree about the threaded spindle, which is why I kept my eyes open
for an alternative Clausing spindle to swap in later.

Not to insult those that have them. Any
lathe is better than no lathe and with an independent chuck the issue is
moot but slow as heck.


Try *all* of your collet-threaded devices just in case one of
them is slightly oversized -- *before* you unchuck it. DAMHIKT. :-)


So far I have no collets. I may turn this at work at lunch where I can
present Hardinge, Buck, Royal, and other brands to it before I call it
done.


In particular, check import collets. All that you have
mentioned above are good ones which will be made to good standards. My
offending one was an import 4" 3-jaw chuck on a C5 shank from a later
eBay auction.

Enjoy,
DoN.
