Feed/Threading gear(s) for small 1950s American Lathe??

[Chuck Forman]

Can anyone help Mr Cheap here acquire or make gears for a small Lathe?

Looking at a nice 1952 Logan 11 X 36 model 922 lathe. Good ways and headstock. Trashed gears in the quick change box. E-Bay has a QC box, but no gears. Any advice RE repairing gears on a small lathe and a Logan specifically??.

I think Logan used the same QC box/gears in 11, 12,14 inch lathes in this era, maybe 10"s also. So might I get gears from an otherwise worn out machine? Any chance if/when I get it apart I can fit off the shelf gears from Boston Gear or whomever to this machine??

Having new gears made is probably out of the question; my old American lathe thing is an affliction, but not yet a financially fatal disease!! That said, if someone has input that laser or plasma or whatever cutting of small (1"-3" OD) gears could restore this lathe to cut decent threads for "reasonable price" pls advise. Likewise if you think Mr Cheap/Novice could actually do it with his worn 10" Sheldon lathe and sound Gorton 1-22 MetalMaster (Bridgeport size) vertical mill).

Thanks for any/all advice!! Chuck Forman

Do you know the pitch of the gears?

I don't think I'd let the gears stop me from buying a good lathe at the right price, you may be able to match the gears up from a place like Boston Gear (might need modification) for a reasonable price, if all else fails making gears really isn't that hard, you have a mill just add a rotary table/Indexing head grind some fly cutters and you'll be in business, there's lots of info on the net about cutting gears, I think the workshop practice series of books has one about gear cutting, good luck.)

Thanks everyone for the great input. Redirish, I do not know the gear pitch; can't measure or be sure which and how many gears are bad without taking the gearbox apart.

Don B: Upbeat input for sure. I'm a novice and thinking more of the "baby steps" approach to learning machine works, but who knows - - -.

Well, I bought the 11 inch Logan and am making good progress sourcing gears.

Thanks everyone for the advice/help. Pleased to learn Logan Actuator (store.lathe.com) has many new parts. Called them; very helpful, but prices are nothing short of shocking!!
