1102079 Enco 12 X 36 Lathe Cross Feed Nut
I inherited a lathe from my late father in law. I'm not sure the model, but my research leads me to believe it's an ENCO 110-0820. The motor RPM, gear selection, and thread cutting chart that is mounted to the headstock has been replaced with another bare piece of sheet metal. I took the lathe apart to clean up the lead screws and to adjust the gibs as the axis were not moving smoothly from being all gummed up. The aluminum cross slide nut has a 6 mm tapped hole to fix it in place which has mostly disintegrated and the screw that holds it in place cannot even catch a single thread. I need help determining what replacement nut I need to buy. So far I know it's a left hand thread. I think it's an ACME thread. I'm finding some info that it may be an 8 -1.25 mm left hand ACME. I'm just not sure. Could this imported lathe have an imperial thread? Any ideas? I'm ready to buy a replacement so if anyone knows what I need or where I can find one please let me know. I'm completely new to using a lathe and this is my first machine. I look forward to learning on this lathe and one day contributing to this group.

Can you post a couple of photos of your lathe? It might help people identify the lathe. I have a Grizzly G4000 lathe and parts are interchangeable with Harborfreight similar lathe, etc. One can buy parts from Grizzly or LMS, etc. With only your description it may not be easy for anyone to respond to your questions.

Its very very simple to make a new nut.
Virtually all my work is metric and it seemed silly having a cross slide that was so difficult to work out simple distances per graduation.
That silly soft nut had heaps of un-removable backlash so I decided to make a new one.
Then I thought why not make a new lead screw for it as well and I decided upon M10x1 mm thread, extend the length of the lead screw, make a new handle with bearings, 100 graduations to the hand wheel, oil grooves in the cross slide.
All these mods were actually way easier than they sound and the improvements have made an incredible difference in the actions.
All these mods came about when I had to change the worn half nuts for the second time and thought it would be good to do it all at the same time.
The complete project can be seen here. https://www.hobby-machinist.com/threads/9-x-20-half-nut-problem.74021/
Charles your project looks awesome. It's absolutely above my current capabilities, but hopefully something I am capable of in the future.
Edit: The part number is P4000804, sorry for the typo..
Kevin
My experience has only been with Grizzly G4000 and your pictures tell me that it is very much like a G4000. You could buy the spare parts from Grizzly.com. Cross slide lead screw nut to part number P4000804 is priced just $8.25 which is quite affordable. You can try it and see if it works for you.

Here are several pictures. As you can see the machine is still apart. Let me know what you think this is. My mother-in-law told me her husband had also purchased a Enco 30 milling machine at the same time he bought this lathe. I have that as well. That's why I'm suspecting this is also an Enco. Just a hunch though. The area uncovered on the headstock has a custom sheet metal plate that is not flat like the original. It has a bump-out to go over that bracket that was added. Also not sure what that's for.
Charles
I think he has a situation where his cross slide is broken due to the broken nut. That makes his cross slide (and his lathe) inoperable. He can not make the nut using the method given in Steve Bedair's page unless he has another lathe to work on. The alternative will be to buy a nut. Grizzly sells it for $8.25 which is cheap compared to the ebay seller at $45.

Hi
So far Grizzly parts seem to fit and work fine in my Enco 9 x 20 lathe. Good service too.

Thanks everyone. Yes, I only have one lathe. I'll get one on order that was suggested and let you know how it works out.
That is a good move. And your risk is low. The site suggested by Charles - bedair.org has one of the best reference materials for 9x20 lathe. According to it parts are interchangeable between Grizzly, Harborfreight, Enco and Jett. Please keep us posted.

Does anyone know why Grizzle don't export to the U.K.?
Hi does anyone know why Grizzle can not send goods to U.K.

Mike,
for some reason your link doesn't work for me, a message about access from the UK being blocked!?

Kevin,
Interesting to see your lathe, mine is the exact same colour but manufactured by Excel and sold in the UK by RS Components (used to be called Radio Spares) in the 1990's

Here are a few suggestions:
You said you also have a mill. You could make the part you need on a mill, with a bit of work and the right tap. You can likely find the tap you need online for around $10-15 USD (added bonus - you add a useful tap to your tool collection).
Your lathe looks to be a pretty standard model 9x20, so there is likely a source for parts in the UK - worth tracking down as a resource for now and later.
Look for another hobby machinist in your area. In my experience most such people are more than happy to help out a fellow hobbyist.

I purchased the grizzly cross slide leadscrew nut P/N: P4000804. Part arrived today. Sadly I think this is not the correct nur I need. I can easily thread the nut onto the leadscrew about halfway. Between half and 3/4 of the way onto the screw it develops an increasing resistance. Just about 3/4 on it binds up completely. To me that tells me the threading is close, but off. If I flip the nut around there is no change. Threads on fine and binds up at 3/4 on. That's also telling me it's not a bad threading at 3/4 in. It's just not the same threading, but close enough that the mismatch isn't apparent until there is considerable thread engagement. The original nut has no issues threading onto the leadscrew and has an even amount of resistance all the way up and down the leadscrew.
Are my assumptions right or am I missing something?
Any suggestions?
