Default Enco lathe repair

A while back I purchased an older Enco lathe 12X36 model 92010.
This is a Taiwanese built one from 1984. This poor thing has been pretty badly treated in the past and I want to bring it back to usable life.
One of the needs I have is concerning the lower gears. Some of the teeth on the lower gearing assembly have been sheared off. This usually occurs when some dummie runs the tool post into the chuck.......
I have been told to braze on new metal and then take file to create the new teeth. I have had good success with building shafts etc up with my mig. But I lack a mill to re-cut the gear teeth.
Of course parts for this are no longer available. The other Jet, Grizzly, etc. ones have different sizes of shafts so I can't adapt one of those.
I am looking for suggestions.

I am not a machinist but those gears look in very rough shape. If it was one tooth I think you could get by with brazing and filing, but I think you have too many missing teeth to do that.

I think you will need to get new gears, or modify some other brand. If you don't have the tools to make some new gears, I think you may have to have them done for you. My $.02.

The question isn't who is going to let me; it's who is going to stop me.

milomilo is correct, those gears should be replaced. I recommend disassembling the gears (taking pics in the process) and then taking them to your local industrial distributor. They should be able to match them up to gears from Boston Gear and all you should have to do is bore the ID.

You should be able to find some straight cut gears that size.

The gears in the picture are trashed beyond repair.

My first call would be to MSC (but you've probably already done that), they were probably the original distributor. Boston Gear would be my second. The single gears might not be a problem, but the small end of the bull gear is going to be. There is a guy on the South Bend Lathe users group on Yahoo that repairs those (can't remember his name). I've never heard any complaints, and hes done alot of them. Good luck with it.

I have a Taiwanese lathe of similar vintage except mine wears the "JET" name plate. It may be worth a call to Jet to check on availability.

That machine looks like one I have.
If it is,you might want to look closely at the entire thing.

Who ever engineered it never operated a lathe.

The apron stops six inches shy of the headstock.
The compound and crossfeed handles are in each others way,
so there is a dead spot where you can't machine at an angle.

The only fix I could come up with was to replace with tiny hand wheels.

The tail stock fit up was a joke,80 thou low and it looked factory made.

Wish I had looked it over better before I bought it.

I still depend on the old Atlas if I have to make something pretty.

I have enco 12 by 36 that looks nearly identical to that one..I busted teeth off the backgear and was able to buy a replacement from Enco for reasonable money..That was 5 or 6 years ago and mine is a little newer machine.. I bet you can get all new parts from Enco.

. I use my Enco lathe several times a week, been a very good machine for the money. I bought it new . I have two other lathes that share the workload in my shop..

I was between mining jobs a few years...28...ago, and took a hard look at my lathe. There it was.
That tailstock issue is one common to a lot of Asian lathes, I bet.
I had the same issue, and I had to have the lathe bed cut down under the headstock. I chose to do that because someone at the factory tried to lower it by using a hand held angle grinder.
The local machine shop refused to mill down the bed, but allowed me to do it using their shaper. First and last time in my life I ever ran a shaper, never mind one big enough to hold 5 ft of lathe.
They hired me as a machinist after I finished, that day.
