decoding a South Bend manufacturing card

j eric townsend
 

Hi,

FINALLY getting around to doing this several years after getting a copy of my lathe's manufacturing card.

https://www.flickr.com/photos/allartburns/51594312424

If I understand things, "RKL" means:

R -- Heavy
K -- Gearbox
L -- Spindle type? Is this the 5C for a heavy?

I thought there would be a FAQ on this online, but maybe it's just not my night for searching the Internet.

I've mentioned that I'm a cheap bastrich, right? You could make your own, if you can cut 1-1/2-8 internal threads yourself, too. I can't yet, Couple more lessons in class to learn that. Anyone care to guess what I'm going to be making when I'm supposed to be working on the class project? Also need one for my SB Heavy 10L, with the 2-1/4-8tpi spindle nose. I have already made stub spindles for both machines so I don't have to go to the machine to test fit stuff I make for it.

I enjoy running my mouth/keyboard, and it makes me happy when folks like that. I hope I'm helping other folks realize that if I can do it, they can too. If they want to. This past week I have been playing with the Smithy 3-in-1 machine. It is NOT a South Bend. I looked into buying one before I bought my first lathe, the HF 7x10, and decided that having to change setups all the time would be a waste of what little shop time I was getting. And since the problems I had with the 7x10 were me, not the machine, things wouldn't have been any better. Now that I have a clue, and two other lathes running, the Atlas & HF, I'm making a big push to get all my machines running. Wife bought me the 10L for Christmas of 2018. It's been sitting here in pieces since I brought it home, but it needs the most work of any of my machines, so it's last in line.

Today, I need to fix the parts washer so I can clean the Smithy spindle parts. found the notchy bearing, and am hoping that a good cleaning & removeal of 24yo dried grease and replacement with good grease will save it. If not, I'll buy a new one. One step at a time. Once all the other machines are fixed, and ready to run, I start on the 10L. it's gonna need more than a bit of work, as it spent at least 5 years in a leaky barn, among other things.

Re: ISO some help

My bad, I inadvertently replied only to the previous poster.  Now for everyone's perusal:

I have, what I think is a SB 30mm to 3C collet adapter for a South Bend mill, 90 degree attachment.  I know that a 3C collet seats nicely in the adapter, and it also has the SB set screw pockets.  It came with a short draw tube.  No threads anywhere on the piece but there is a dimple inside to keep the collet aligned.  I would like to verify that it is indeed what I think it is, and have an idea of a reasonable price to sell it for.  I've attached a photo, and could provide additional photos and measurements if needed.

Any help would be appreciated,

Thanks,

Greg.
