South Bend 9A restoration happening w/pics!!

[SLK001]

Update: I disassembled the apron and incase people don't know this, there are a million parts in that sucker!

999,967 of those parts are swarf from the lathe's previous life. Don't count those!

Mine (Enco 12x36) had extra roll pins sitting in the bottom of the oil bath in the apron. Convenient to replace the 2 that I damaged disassembling the lathe

I guess all is not well on the site but those things happen. Glad the site is back up and hope it does't have a repeat.

I have finished the cross slide and compound rebuild with new screw nuts in both. Still waiting on another new bearing for my QCGB tumbler. I ordered a new/used clutch gear for the apron. Built another plywood table base with new swarf pan. Maybe tomorrow I'll start cleaning and painting the tailstock and taper assembly. Starting to feel like I'm going into a burn out state as everyday for the last month I have been working on this lathe or another.

Painted the apron this morning. Kinda cool this morning so not going to get much done today. I had ordered a new clutch gear and the pic shows just how worn it is. Re-assembled the cross-slide and compound yesterday.

Looks like my tumbler gear bearing problem is a little bit of a problem. Someone on another forum had the same problem as me with the new B-88 bearing. Seems what I needed is the B-88X which they don't make anymore. The B-88X was slightly smaller OD and that is why when I pressed the B-88 in, which was tight fit, it would seize up on the pin. Here's a quote from another site.

"The new B-88 roller bearing would not work in the original tumbler gear bore. It seems that the B-88X is an undersized bearing on the OD, and not available. I had to ream the bore of the gear out to 0.687" to make it fit properly."

The OD of the B-88 is .6875 (11/16"). Looks like I'll have to do the same. A little later today I'll Mic the ID of my gear and see what it is.

Reamed the gear out and pressed the ruined bearing back in and pressed in just fine. The ruined bearing has fouled needles so I can't reuse it. The new bearing was "supposed" to arrive yesterday but snail mail didn't deliver. Not sure what a "good" gear looks like cause I don't have one to compare it to.

I'm cleaning and paint the tailstock today and notice there is only one long allen screw and the other is missing. Is there anyone willing to measure their tailstock allen screw lengths for me? I would really appreciate it! Looks like someone has tried to do an upward lift alignment for tailstock base and Vee wear on the upper left corner by bronzing it. I would think that without two adjusting screws that alignment would float around.

I just can't seem to get ahead on this darn lathe. Now I find that the tailstock base plate "V" is larger than the lathe bed "V." The base plate rocks on the bed "V" and is probably why someone had bronzed the corner of the base plate trying make it work. The casting part number on the tailstock is 10D-5. Can someone verify that it is the correct tailstock by matching their 9A tailstock number?

glue in a thin strip of plastic or brass to bring it back into alignment

The base plate V is larger than the bed V. Actually I don't think the tailstock is even for a 9" SB. That's why I'm asking for a casting part number from someone's 9". The pic second pic is what a 9" tailstock looks like and it looks different from mine.
