WTB: Gearbox for a 1943 Round Dial 10ee
My dream lathe sits in my garage waiting to be cleaned up, painted and used. My 1943 U.S. Navy Round Dial machine is in good condition but has a frankenmotor setup in place of the original drive. I will be removing all of that and replacing with a 3 ph motor and VFD. I would like to add an original gearbox back into the power stream, but can't seem to locate one.
Anyone have a gearbox for sale?

You might try Monarch Lathes, I've heard they have a supply of used 10EE parts at reasonable prices. They may have gearboxes left over from when they did some VFD retro-fits using a 10 h.p. motor and no gear reduction box.

David, Great idea! That option never occurred to me. I'll call them on Monday. Thanks so much!

I received a call back from Monarch today. Though I did buy a set of felts and a manual, they don't have any suitable gearboxes for sale. Thanks for that great idea though David!
Still on the hunt...

Those of us retaining any of the 10EE's DC motors stick with that gearbox because it is a bolt-up fit as well as a proven match to the need, more compact, long-axis, than most other options, and adds no vibration when not asked to perform at the reduction ratio.
A 3-Phase motor going into space that no longer has even the need of the DC panel would not necessarily have to use 'only' that gearbox.
In an MG base casting, and perhaps others, the motor would not even necessarily have to live in the same compartment. It could be relocated TS-ward, Lovejoy and (supported) driveshaft go HS-ward to a reduction system - belted and clutched, even, rather than geared.
I'm not looking to add to the count of "Franken10EE's" at large, but the supply of gearboxes resembles awaiting promotion on the US Supreme court.
One has to wait for a more seniour officeholder to retire. Or even die.
10EE part-outs that release a still-usable gearbox back into the pool are not a great deal more frequent.

Check with Lost Creek Machine, they were parting out a 10EE.
