Sheldon Lathe Identification

[BSchulz]

I recently acquired a Sheldon Lathe and have what i can make out of a model number and serial number (all be it rather beat up and hard to read). I am trying to make a positive identification so that i can get a parts manuel and operations manuel before all the markings on the various name plates are gone.
The Model number seems to be GR72B and the Serial # seems to be GR25920.
I have yet to find any pictures that can help in the identification, but i can include a picture as received.

Welcome to Hobby-Machinist Forum.

I have almost the exact same lathe in my shop that I'm rebuilding. Mine is a "ER" version that has step pulleys to get the various speeds. Yours is the "GR" version that has a four speed transmission driving the headstock. Mine is serial number 25267 that's 653 serial numbers greater than mine. Mine was born in 1960. Yours may be born in 1960 or 1961. GR72B indicates it has the four speed transmission gear motor, has a 72" bed, and the "B" should be a "P" in the model number. And it's a 15" swing lathe. I have a instructions/ parts manual of the "ER" version but does not cover the four speed gear motor on the "GR" version. Rest of the manual is the same between the two lathes. If interested in the manual, I'll be glad to up load it into the "downloads" section for downloading. Ken

Oh, be sure to go over to the Yahoo groups and join both Sheldon Lathe groups for additional information. BTW-My current rebuild is my second one I've done over the years. I'll be glad to help where its needed. As well as other sources for repair parts other than B & K. Ken

Ken:
Thanks for the quick reply.
Yes i would appreciate the manual if you have it available at least it will cover the compound and headstock. The lathe was in reasonable condition, but needs some TLC. The motor was rewound for 575 volts and i am in the process of having it reqound to 220V 3P with a Rotophase to power it. The heastock, Compound and gearbox are all cleaned up and now need to cleanout the motor and gearbox compatment. yuk. doesnt look like that part has seen a vacuum since it was new........ The compound and ways are in good shape and tollerances seem to be rather well preserved. once i get the stator for the motor back should have a good lathe for the hobby shop and Farm (and of course the neighbors).
Thanks for the tip on Yahoo Groups.

Here is the link to the Operation Manual.

If you ever need drawings to any of the parts in the apron. I have reversed engineered and drawn up every part in the apron. Let me know. Too many to up load here. They are loaded on Sheldon Lathe 2 group on Yahoo if for some reason I'm no longer around.

Ken

BTW-If you haven't serviced the apron, I advise you drop the apron and give it a good cleaning and make repairs where needed.

Welcome to the best site around. I to owned a Sheldon but being younger I sold it to buy a boat. Dumbest thing I ever did. I had tons of tooling the RPC , it had lever collets three chucks , crank variable speed and it was great. Ok I'm kicking my own butt . I don't recognize yours but I bet it will turn out to be a good working machine.

Look under the Sheldon Lathe 2 group. And it's listed under "Ken's 13 Sheldon Sebastian Lathe." Both lathes use the same apron.

I have just ran into my first proble, with the compound.... Refering to the parts list you previously provided Page 14 and 15.......
I am trying to take apart the upper slide Part # 12 and Part # 19 Swivel. There are 2 adjustment screw for the GIB Part #21. The one on the non handle side is free to turn with little or no resistance, however the one on the handle side has a piece bent over the adjusting screw. It is steel covering about 1/3 of the adjusting screw head. I can move the adjusting screw, but limited by the piece covering part of the screw. It binds in either direction and does not seem to be hindered by this bent over piece, but may be wrong. I assume that the bent over piece is part of the gib appears to be a cast surface.......... Needless to say I can not move the slide. I have removed the 2 set screws #23 and given it several good smacks with a brass hammer to no avail. Before i get to froggy with the hammer I thought iIwould ask someone that has a working slide. I can send a picture if that would help.
PS finally got access to Yahoo groups. Good information. Wish the price list was still in effect.

Post a picture or two. Sounds like someone got the gib jam in there too good.
