10EE Spindle taper

Steve, I will call Clausing today to find out for sure.

Thanks a lot for your help.

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'm a little confused here. Just did a search for "Clausing 10EE" lathe and came up with nothing. Wasn't Monarch the maker of the 10EE?

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.

i

Yup. Clausing made a 100 and 200 iirc.

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.

L0 taper, 13" swing, according to Clausing, my lathe uses a reducting bushing of unknown OD to reduce spindle to MT3.

What is the ID of spindle tube?

Is this useful?

Wes

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 mat>

Steve, I have a Clausing Colchester. I will double check for the adapter, but I believe that I do not have it.

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.

Clausing Colchester Master, 1967 model. Four year older than myself. 13 inch swing. I will measure this stuff tonight.

Four inches longer than yourself?

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".......
