I have a 9b-17-1 Logan that I aquired last week. The retaining mech for the compound slide screw broke or is missing and I can't seem to find it or a part number or what it is actual called to get a replacement. So it just now unthreads and threads but won't move the slide.

Hello and welcome to the group!

I am not familiar with the Logan models numbers.
There are a few manuals available here:

Have a look, maybe you can find an exploded view and part number.

I believe some parts are still available for Logan machines.
Hopefully a Logan expert will stop by this thread with some real answers soon.
Good Luck!

I'm trying to figure out which part you're missing. Is it the threaded collar that screws into the compound?

I'm not a Logan expert, either. But 9b sounds more like a South Bend model number than a Logan. Logan model numbers all seem to be 3 and 4-digit. For example, a Logan Model 400 is one 9" lathe family. Best bet would be to start with a photo of the machine's nameplate. And one of the carriage, cross slide and compound.

Here's a PDF of a larger Logan than yours: not the same machine but there's a good chance the compound
is put together the same way. If you remove the compound you can see if the compound rest nut is present:
if the handle turns but nothing happens the nut is probably the culprit.
You can also contact Logan directly by phone: they have the correct parts manuals and operators instructions for your
machine, and can supply parts as well. http://www.lathe.com is the link.
As brino said, you can also post pictures of what you have and we can help you that way.

what we really need to know is....is the screw thread turning.. the part under the compound... there should be a removable panel there covering the threaded rod from chips... or when you turn the handle is it just slip;ing on the threaded rod that is suppose to move the compound. there is a sleeve joint on mine that has failed... unbolt the saddle take it off have a good look.

Are we talking about the cross slide, or the compound? The OP, who seems to have gone AWOL said compound.

I was thinking compound. From his description it sounds like the screw is backing out of the compound casting instead of pulling it back.
