This looks like a quick release 4 way toolpost for an SB Model A. Never seen one before. Is this thing somewhat rare?

The thing to the right of it looks like a multiple position carriage stop.

I have a heavy heart because I need to either keep or dispose of a 52" bed Model A, lightly used, with just about all accessories (including taper attachment), Cushman 3 and 4 jaws, several like new Jacobs threaded spindle chucks, etc., from the SB catalog in 1948 including the order sheet. Problem is, I have enough lathes now with equal or better capabilities. It's grampee's machine but grampee also has huge nursing bills. The machine does have the longest bed and the TA is something I don't have elsewhere. What to do http://bbs.homeshopmachinist.net//rolleyes.gif http://bbs.homeshopmachinist.net//rolleyes.gif ???

WHATTTT? You would sell off a family Airloom, and a piece of American History??
My model c came with a 4 way tool post, but it had an old metal tag on it saying "Enco" hehe.

That toolpost looks like a quick retract post used for threading.
Pull the lever back at the end of the thread to clear the work, wind back to the start, push the lever in, put the fresh cut on with the top or cross slide depending on how you work and take the next cut.

George Thomas did a similar item for the Model Engineer but this was only a tool holder and not a comlete post, see:-

I'll have my hands on it this weekend. It looks like it is 4 way but without a center post, I thought it maybe released from below with that lever.

Oooh ! I think I just got it, it's not 4 way, it's for holding external or internal threading tools / bars, right?

BillH, Yes, it is a family heirloom ... my head hangs in shame http://bbs.homeshopmachinist.net//eek.gif and it may end up in a warm cozy corner with a picture of Grampee above it!

But ... add it together with a 1300lb letterpress, 750lbs of lead type, 1200lb paper cutter, 500lb post drill "hanging" on a postand MUCH more and you start to get the picture.

Yeah, I've seen those tool posts before, but don't pay too much attention to SB stuff.

I've got an SB accessory that may be rarer. It's a 4-1/2" diameter rotary table, RTB100. Nice heavy construction for it's size. Someone told me this might have been intended for mounting on a cross slide as part of a ball turning setup. Hard to imagine it's use on a mill because of it's small size, although it'd be fine for smallish work on a smallish mill. Did SB make small mills? I've seen their almost B'port sized ones, never a smaller one though.

the small rotary table is seen in my catalog next to shaper accessories. my rare sb attachment is a turent style tailstock, doesnt say SB on it that I could find, so assumed it was just an aftermarket item, then low-and-behold this old catalog that I just found has it as an option, cost about 180$, the regular bed turent was a bit more at 220 or so. can see tailstock at my website

If I had money Nheng, I'd say put me on top of your list, I want to start a South Bend lathe refuge to keep these lathes out of the hands of those Ebay scrappers. Truly though, you should keep it, and pass it down to you kids and so on.
