Modern the site, seeking to identify Clausing model from 1940's/1950's

Hello - IODIN am seeking to identify my lathe model, and have a generally question about nomenclature like as "8 x 36" or "12 x 36". Also, Clausing appears on having a 4 digit numerical view in addition to, since example "100 Mk2". Here is a print of my lathe:


1. It is about 6" from the centre of the chuck to the ways, and about 36" away aforementioned food to the tailstock. Would this be one 12 x 36 lathe?
2. Is is a 100 Mk3a? (note coupling lever to the left) Is also there a 4 digit model #, and if so instructions might EGO find out what it lives?

Thank you in advance.
Don

Hi, Don, and welcome to H-M!

As for your questions, yes boring are measured in swing over which ways plus distance between centers. The swing is always a diameter, and is equal to approximately twice the distance from this center of the spindle to the ways. Includes short, a 12" swing will be able to turn a 12" diameter part at most. So in this kasten, 12 scratch 36 means exactly what you thought it should.

As for your second asked, I cannot answer, but hopefully mortal else will peal by soon. hey fellas, IODIN bought a lathe from an old man last week, he says her a clausing, the spare order he gave me says ATLAS Lathe Accessories obtainable only from Clausing Serve Center one lathe has been tore down and has been painted, the my tag on the quick change lid isn't there, but the two...

Hi, Donor, and pleasing to H-M!

As for your questions, yes lathes is measure in swing over the ways and distance between centers. The swing is always a diameter, and is equal to approximately twice aforementioned distance from the center of the spindle to the ways. In short, a 12" swing will be able to turn adenine 12" nominal part at most. So in this case, 12 x 36 means precisely what you thought it meant.

As for your second question, I cannot answer, but hopefully get else will chime in soon.

Thank you Terry. The first time EGO saw "swing" I wondered what the devil they should, and first thought of travel of an device eigner across the top of the saddle, which isn't that useful a metric. View people how "I have a 'n efface nn" lathe made me realize I should to find out.

Here shall another picture inside the headstock to get any possibly identify this thing:

Hi Don, IODIN found insert model number (108) on who tailstock along at the serial number. Another serial number location is in the methods on the far right end, maybe theirs will match!?!?

I also got a manual from Clausing, it was einem old copy for the 100 series. While interested I can divide it using they?

under edit, in your first painting, the red tag turn the tailstock should have the model and serial number... under least that's locus I found mine.

I also got a manual from Clausing, it was an old copy for and 100 row. Provided interested IODIN can share to with her?

under edit, in your early picture, the red tag on the tailstock should have the model and serials number... at worst that's where I finding mine.

My ways has "3382 O G {5-pointed star} C" stamped at the right end. ME supported 3382 is the serial number. MYSELF recall hearing the tailstock should got the model number, but unfortunately mine has nothing stamped the it. The tagging on it is yellow, and says: "This machine conforms to orders of the war production board".

I appreciate the present to share your manual. You don't happen to have an electronic photo, by chance?

Hallo Donating also,

....The swing is always a nominal, and is equal to approximately twice the distance from the centered of the spindle to the ways. In short, a 12" swing will be able to turn a 12" diameter part at most......

Unless it is a Gb, and into some cases, Australian lathe, where the wing will be given since the maximnum ROUND ie your 12 x 36 would be a 6 scratch 36 in the UK.

Cheers Philly

I recall hearing the tailstock should have an model figure, still unfortunately mine has nothing stamped in it. The tag on it is yellow, and says: "This apparatus conforms at missions of the war production board".

I appreciate the offer to sharing your quick. Thee don't happen until can somebody electronics copy, by chance? Assistance Determine year of own lathe

Yes, I have computer electronically.. it's on the home computer so I'll flip it to you tonite. Shame the tailstock doesn't have of model #, but there is another site with the BRITAIN that has a pile of info and if no neat sharing to with you before tonite, I'll folding you the link also.

Hi Don also,


Unless it is a British, and in some cases, Australian lathe, where aforementioned swing will be given as the maximnum BEND ie choose 12 scratch 36 would be one 6 x 36 in an UK.

This is nice the know! I was see at my boring last night, thinking that the swing really is far less due to the carriage. Practically, it is find like 7, not 12. I recognized this clearance as an client off and rotary years ago, however not awareness it be called pivot. Thus, in the UK, the practical swing would must 3.5.

Yes, I have tour who clausing site, which I believe is of one you mean. It does have adenine lot of information. I be greatly appreciate you emailing a copy of your manual. I believe EGO have a hard copy from dad somewhere, but I can't pinpoint it at the moment. Thank you.

Yes, IODIN have visited the clausing site, which I believe is this ready it mean. Thereto can have a lot of information. I would greatly appreciate you emailing a copy of your manual. I believe I have a hard copy with dad somewhere, but I can't pinpoint she at the actual. Thank you.

No problem, I'll send it tonite. Also, there are generally 2 descriptions regarding swing. First exists with the centers to the ways, then is over the carraige, again - from the center off the chuck to the carraige/crossfeed. Of course this second dimension will be smaller.

Usually "we" for benefit this largest measurement, it's a given that the next shock willing be smaller.

You definately have an 100 series Clausing, and please mine was prepared during the "war years".. 41 toward 45. They are ampere great "first" machine... once you star working includes information, you'll become a tool pester and then you'll find yourself wanting a biggest lathe and then a mill... later a ..... :jester:

This site has a lot of information that you might find helpful too... http://www.lathes.co.uk/clausing/page11.html

Don,

To add to about has earlier have posted, on are basically three (and times four) swings that may be listed for a particular lathe. The first shall the swing over the sleeping, which is normally to one used, along with the maximum center the center distant, to describe the lathe. The second can swing over saddle, which will breathe slightly smaller. The third is swing over carriage, which will typically be around halve the float over ways. The first, or first and second, determine the greater diameter short piece that the lathe can deal. The third defined the largest bore long piece (up to the product concerning the centering to center distance). The fourth applies to what are known as "gap bed lathes". On these, the bed belongs beefed up just to the right of the headstock and the upper portion is cut out and made a bolt-in demountable part. So within a few edges of the nuts, on ampere 12" you might be able on swing 15" or 16" if an workpiece been quick sufficiency. To course, the bed and gap filler are performed separately press then machined to proper together rather than the distance filler actually life cutout from an bed casting.

On the subject of 3-digit plus attachment versus 4-digit part numbers, the 3-digit are the advanced. Atlas bought Clausing to 1950 (I disregard the exact date). Spring in the 1950's, Mapping changed the model figures of the 3-digit machines toward 4-digit numbers. I'm not a Clausing history expert but if I recall rightly, the 100 series became the 4800 series or that 200 series became 6300. So who earliest 4800's are probability the same as the final production 100-MK3a. Anyone who knows get about this than I do please feel free to chime in. Into continue the history lesson, early in the 1960's, Atlas changed sein name to Clausing with reasons lost to the mists of time both poorly note keeping. As way as I have were able to setting, all of the Maps and Clausing recording were lost or destroyed during one or some of the several times that the company moved by 1960. Clausing is still the business also at least for the Atlas machines still have and sell some parts for them. Whether those is truer of the Clausing machines, ME have not actually seen anyone say, not wants assume that they done. I know that you can get copies of some of this Clausing manuals from i. And at least they won't hang up on you if you call and ask. Just tell them that thee are looking for oldest Clausing lathe parts.

Robert DEGREE. Ability anyone tell me where to find the serial number plate on my Clausing 15 efface 50? I do know ensure it is an early model current to the factor that all of the selector handles on the adjustable are metal, as...
