I bought a South Bend 9c lathe that had been dropped. The screw and idle gears have be broken. Does anyone know were to get one or will a 3d printed gears work as a replacement.? Also if 3d printed

3D-printed gears should work just fine. As long as you don't drop or crash the machine. There is a groups.io group for that purpose (among other) that I happen to own.

Should be able to find any gear you want here; https://www.ebay.com/sch/i.html?_from=R40&_trksid=p2553941.m570.l1313&_nkw=South+Bend+lathe+9+%26+10K+gears&_sacat=0

I bought these Metric Transposing Gears for my 9A, which I believe to be some form of nylon. They work GREAT. Keith

I would like to thank you all for your help. I tried to fine the gears on Ebay with no luck finding a match for the ones that were on the lathe. The idle gear has a 6 to 1 ratio with the large one

I know there are many that want to keep their lathes as close to OEM design as possible.? For them, if it came with change gears, keep the change gears. However since I see that you might consider

Do you have a 9 Junior lathe? Have you checked the s/n and what is your diametral pitch?

You should have probably mentioned that he needs to know the DP of the gears he wants to make so he knows how big a printer he needs to buy. My Atlas TH42 uses 16DP gears. The 127-tooth gear for

To answer the first question: I don't believe that the lathe is a junior. The second question is that dp is 18. I have already model the gears in cad and have ,stl files for making them. My experience

Sounds like we can all help each other! Too cool! I'm several sorts of mechanic, no sort of expert at anything, but I have fun doing a bunch of stuff. I have, I think, already mentioned my 3d

??? ??? theres this one also , I'm not quit sure where they keep the info , cause I haven't gotten that far myself 1. [email protected] </g/AtomicELS> animal

???? you might? ? give these guys a call , there's another place that has some SouthBend parts? but I can't remember the name . I keep thinkin it's something like Horizon , there's also a list

The gear tooth counts you say you're looking for--116 and 108--strike me as odd. My 9C has the full set of change gears, and the highest tooth count is 80. Do you have the gear cover with its graphics

The Atomic ELS is, IIRC, a Russian invention. Most of the info is on a site in Russia, I think. I'm a member of the IO group, but never made it to the Russian source. I'm not nearly ready to go there

I can't answer your questions, but there was a 116-tool SB change gear on Ebay just a couple of days ago. Heck, found it

Great group they have lot good ways to things with a South bend. Dave

I am using an 80/63 combination which is basically the same as 127/100 for transposing.

thank you Bill in OKC too I just purchased the the gear on Ebay. The last part that I need now is the Idle gear. All the other parts have been purchased. The damage done were to the following parts:

Anybody know of or have a possible resource for one of these? Obviously bought used. It has the taper attachment but not the steady rest. Kinda need one of them to do any barrel profiling!
