Craftsman...what flavor?

You're pretty amazing Robert. I guess I didn't mean it was a 9", more that it was from the linage. Either way great info.

I did dig deep on the conversion parts but I'll take your word for it.

Why the concern over babbit bearings? I have one Timken head and one babbit head, and it might surprise you that the Timken head lives in my spares cabinet. If the babbit bearings are in good shape, kept oiled, and are adjusted correctly, they run very true. 82 years of service and going strong. Just sayin'.

I'm just thinking about the hoops I had to jump though to get my 6" running the way wanted. That's a different setup but the basic idea is similar. The way I see it if the bearings are worn and the shims are all out it's kind of game over.

Testing it with an indicator is a good plan, if you see some slop then it's gamble time. If it has adjustment left you win, if it doesn't you loose.

I think the other "X Factor" here is what's not in the pictures. If its just as it sits and it is in usable shape it's a good deal. If there's a set of collets sitting somewhere out of the picture (it does have the milling attachment) then that changes things yet again.

The tall compound is the tip-off that it's a twelve. The ten is shorter.
Babbit bearings are fine if they are in good shape, but if they're not it can be a pain. The roller head gives you zero runout without too much hassle, in my humble opinion it's the better setup, and the reason they command higher prices
Robert D's encyclopedic knowledge of all things Atlas is pretty impressive- He knows way more than me and I know a lot, and thanks to HM am learning more every day

Atlas built and Sears sold 14 different models of the 3/8" bed 12". 6 have roller bearings but only 3 have power cross feed. In order to change the 101.07383 to have power crossfeed, you have to change the carriage, the lead screw and the right lead screw bearing. Which if you look at the "big picture" is a little strange. When Atlas came out with the 10F, they continued to offer both roller and babbit bearings but both versions had power cross feed. Sears, on the other hand, stuck with the 10D carriage on the 101.07383. So it only has manual cross feed.
 
I'm going to take a look at it. I can always walk away.

Really this is just a king sized version of my 101.07301. The larger capacity would be nice but I haven't had a project that the 6" couldn't handle. I know that's not a good indicator though since the 6" is really small and that day is coming. Also the 3/4" spindle hole on the 12" is kind of a bummer, I wonder why they stayed so small on a relatively large machine?

Converting it to a power cross feed doesn't seem all that economical, why not just take that money and look for a machine that already has it. I've also found out how quickly "little" repairs can add up, my 6" works great but I'll never get my investment out of it.

What it comes down to is the extras. If I wanted to get a milling attachment and a steady rest for my 6" it would cost about what this whole 12" is selling for. If the underlying lathe is a worn out though those attachments are not going to do me any good.

K,

The rusty lathe in New Glouster is a 10F. But it is not a TH42 because it has a vertical countershaft, not a horizontal. Assuming that the rust isn't deep, it would supply the carriage and leadscrew bearing to convert the 101.07383 to power cross feed. The leadscrew would have to be cut off and the left end turned down to 5/8" to match up to the left bearing on the 07383, which is doable. But the headstock is a 10", so not a replacement for the one on the 07383.

As to why the Atlas 10" and 12" lathes had 3/4" spindle bores, it was because anything larger would have required a larger spindle and a larger thread or different type of chuck mounting. Plus larger bearings, larger gears, larger headstock casting, etc. All of which equals more dollars. The comparable Logan and Clausing 10" or 12" lathes of the period are mostly all the same. Atlas never would have gotten into the lathe business and we wouldn't be having this conversation this afternoon. :calm:
 
The lathe found a home that wasn't mine. It would have been interesting to get that 10F to see if the carriage was be sound enough to be transplanted. Honestly if it was closer I would go check that 10F out just to see how much of it could be salvaged as parts.

You know, I've looked at Logans and South Bends and they're all pretty much the same spindle hole size so you're right.

If nothing else I learned some stuff so the next time one comes up I'll be that much ahead of the game.

Thanks,

K
