    Southbend 9A lathe 4 jaw replacement chuck brand?

    Hi Pern. Timely question. I am also looking to get a 4 jaw for my 9A. Do you want an independent jaw chuck or self centering? If self centering Google K72-160. Less than $100, but you’ll also need to get and fit a breaded mount for it. For the price I suspect the quality is mediocre at best. I...

    Threading problem model 9 a

    Jordan, the 40 tooth stud gear cuts the tpi in half for the top row of the chart. You’d notice that large of a gear in there, and there is no 30 tpi on the chart anyway, so nothing to cut in half to get 15. Just a guess but the inner gear on the stud gear is 24 tooth (the one that contacts the...

    I cut a strip of letter paper and laid it between the spindle and forward gear and pushed the gear into the spindle. I removed the pinch bolt from the lower casting and removed it to get the set screw under the slot on the reverse tumbler and ran it in until it hit the hold down bolt. The mesh...

    Thanks SLK001. That did the trick. It sounds much better in all speeds and both directions now.

    I was messing around with the reverse tumbler gears tonight and put in in neutral and found that it is even quieter without the lead screw turning. Then I noticed that it was relatively quiet when the lever was engaged downward, but upward had a ton of gear noise. The gear lash to the spindle...

    That was a quick answer! That makes complete sense on the lead screw. Still so much to learn. The second card does show a number for the tail stock but is blank under steady rest so I assume that means one was not ordered with it.

    I just received my serial number cards and this lathe was made in July 1952, and sold to the newly opened Gordon Tech High School in NW Chicago. DePaul College Prep - Wikipedia I’m a little disappointed that my card appears to have been water damaged, but it is what it is. No wonder the bed...

    Thanks Mcload. Yep, the under mount drive definitely leaves less moving parts exposed, but the real advantage for me is that it can be closer to the wall. This lathe sat unused for a few years in an unheated shop so it had its share of rust from spring time condensation on it. I blew thru an...

    Hello all, I have wanted to add a lathe to my shop for a number of years and the right opportunity presented itself recently. It is a catalog #CL344 Z, 3 1/2’ bed UMD, SN# 29858NKR7. I believe it may have been built in ‘51 or ‘52. It did not come with any tooling or attachments to speak of...
