For those of you who may care, the spindle taper of the Clausing 10EE is a
number 12 Jarno taper. I discovered this trying to help resolve Iggy's lathe
issues. So perhaps some of you may know of a source for 12 Jarno to MT, 5C
collet adapters and a test bar in anticipation of Iggy's request. Jarno
tapers are identified by a taper of .6" per foot and numbered in 1/8" at the
major diameter like 12 x .125 = 1.500" major diameter.

Well, Steve, as the saying goes.. it couldn't have happened to a nicer guy.
Options will likely be expensive as far as having the convenience of being
able to use 5C collets.. replace the spindle, have the spindle recut and
reground, or fabricate an accurate adapter for 5C collets.
If one had the capabilities to fabricate adapters, they might bring a
handsome price.
Ig's intentions may have been to see how accurately the machine is set up,
and quantify any wear, but much of that is unimportant if the lathe is
capable of making quality parts, which it very likely is, if there are no
signs of major wear or damage.
Steve, whyn't you ping Ned Simmons? He supplied some filament transformers when
I helped a friend
overhaul a 10EE several years ago. Ned is a major source of 10EE smarts and
parts.

Do you mean Iggy's Clausing uses the same Jarno taper as a Monarch
10EE? Someone was selling new 5C adapters for 10EEs on ebay. They're
also available from Royal, but not cheap.
I got off the phone talking to Clausing. The findings are as follows:
1) Outside spindle taper is LO (which I knew)
2) Inside spindle taper is "MT3 with bushing", the OD of bushing is of
unknown taper and Clausing does not know anything about the OD of
bushing.
So, I think that I will return the MT5 test bar that Steve L so
generously lent me, and will try to find some other way of testing
this lathe.

Garrett,
I believe Monarch bought Clausing, as well as Lodge & Shipley and recently
South Bend. The 10EE is Clausing and Monarch both. I believe it is the same
machine. The SB 10 lathes use MT3 spindles. The 10EE is a heavier machine
and therefore seriously doubt the MT3 spindle taper. Iggy, I also have an
MT3 test bar and could send you that. Please accurately measure the major
diameter of the taper and I will bet you $ to doughnuts it is 1.500". The
number 12 Jarno taper is very close to an MT 4.5, but not MT3.
Steve
I believe that Clausing has been owned by 600 group for some time and I'm
just about certain that Clausing never made a 10EE model let alone the
Monarch 10EE. For reference:

Monarch does appear to own Lodge & Shipley:

South Bend now appears to be owned by LeBlond:

I also suspect that Clausing meant that Iggy's Clausing lathe used a MT3
dead center in an adapter that was mounted inside the spindle nose. If it
has an L0 spindle it must be a 14" lathe (6900, 1500, or?) or maybe one of
the Colchester series.

What is the ID of spindle tube?

Wes,
Yes, it is useful, but Iggy must accurately measure the spindle. I believe
his 10EE has a L00 spindle, not an L0, which is why my MT5 test bar does not
fit. Measuring the nose diameter will resolve this. Jarno and MT tapers are
close but not the same. If he has a 1.5" nose, he has a 12 Jarno.
Ultimately, he needs the MT3 adapter, but if he wants 5C collets, he will
need a 12 Jarno to 5C as well.
Iggy,
Do you have a mating MT 3 adapter?
Steve
Ig, you could also call Royal and ask them. You may not want to buy
the taper adapter from them (especially after you hear the price), but
they have lots of accurate info on spindle tapers for lathes still in
production and those long out.
Pete Keillor
Yes. The old trick used to be that smart manufacturers provided
purchasing agents with "specs." I think I still have a lot of them
from companies that sold to schools and colleges back in the 60's and
70's. Using the supplied specification, one could spec out a
government buy with a minimum of effort.... and that is why a
gazillion Monarch 10EE machines were sold to the government.
Several other manufacturers (like Hendey and Sidney) got wise to the
idea and met the government spec provided by Monarch (that cut the
10EE out from the rest of the herd). Now, if we could only find that
old spec for a "10 Inch Tool Room Lathe".......
