Derrick,

I'll answer the rest of your PM here. The machine is an early Craftsman 12x36. First, if it has back gears, it is not a 101.07360, which was an 8-speed machine (no back gears). I take it that the nameplate that should have been on the back of the bed was removed by some PO and lost. It could have been bought originally as a 101.07360 and then later the PO bought and added the back gears. Which would have turned it into a 101.07380. You need to acquire a copy of the correct MOLO version as well (see previous post).

I just created and uploaded the basic instructions for adjusting babbit spindle bearings. Includes the headstock section view.

I've been through all of the pertinent Craftsman parts lists and there is no part numbered L6-252 shown. The part with sequence number 252 is 10-252, used up through 101.27440.

Judging by the two-piece change gear cover, the bed legs, early pattern tailstock and the round knob instead of two-handle 10D-308 crank on the compound feed screw, I'll guess that 101.07380 is probably correct. 101.07381 should have the later one piece cover, wider feet, and the crank on the compound. Otherwise, the two models are the same. At a guess, it was made in 1936, one of the earliest Craftsman 12" machines.

Where did you find L6-252 stamped? Generally, the only Atlas parts with part numbers actually on them are cast iron parts, and the number is raised, not stamped. Serial Number of the machine should be stamped on top of the front way near the right end.

I have to go burn burgers now.

Thanks Robert for the info. I'll have to check out the babbit bearing spindle adj . The L6-252 is stamped into the right end of the front way. I have since gotten a steel compound swivel with crank and better grad wheel. I guess i could be confused about back gears there is no nameplate on the back.
Thanks
 
Well, I'm going to guess that the serial number is 252. Which, if the machine started life as a 101.07360 or a 101.07380, is believable. And also the earliest serial number that I have seen. But that's the first example of an "L6" prefix. There are several examples in the database with 12L prefix. And some with 6L but they are all 101.07301, which is a sleeve bearing 6X18. Both groups are from the 1950's.

Are you sure that there is a hyphen between the "9" and the "2"? That will be the first example of that, as well.

One other thing - in Downloads you will find several Atlas Technical Bulletins. Download the one on the 10" and early 12" headstock. Although it covers the Timken bearing headstocks, the back gears are the same as on the babbit bearing ones.
 
That looks a lot like mine, except yours is much cleaner. I can get you some pics of the gear arrangement if that would help.

Also, here's a guy that deals in Atlas parts. I haven't used him but he seems to have a pretty good supply.

Found a few in the archives.

Thanks Robert & Rick been useing old atlas, seems to work pretty good for what it is and what i got it to do. And its helping me refurbish a SB heavy ten i picked up. problem is oil dosn't stay in spindle cups long 20 wt, was thinking of putting felt wick in the cups. What ua'll think should the cups have felt wicks?.
thanks

Derick,

Atlas added felt plugs to the spindle oil cups in 1968. They can be retrofitted to any model. Part number is 557-097. They are approximately 9/16" diameter and 5/16" tall. Made of gray felt, fairly low density. You could buy a sheet of felt and a 9/16" arch punch and make some. Or a year and a half ago, they were $1.00 each from Clausing.

Rick,

I've bought quite a few things from Joel at MyMachineShop (turret tailstock, lever tailstock and lever 3AT collet closer for starters). He's a decent sort. He also has a some things for the Atlas mill.

Thanks for the info and testimonial. I may have to add felts to mine later. And I'm sure I'll probably need some stuff from Joel.
 
I have an old Atlas-Craftsman very much like dlane's. Mine has a cast gear cover instead of the sheet metal one and I don't have a switch box on the headstock, just a hole for a switch in the casting.. Mine is a dark blue which I think is its original color as there is no other color underneath and there is no paint smear from a repaint on the Craftsman badge, and it spent a long time waiting for a new home when its previous owner died 20 years ago.. 5/8 lead screw, babbit bearings, the exact same knob on the compound, 3/8 thick ways, a tailstock with no oil dobber, and no I.D. plate. Not even holes or any sign there ever was one. Now I need to move the tailstock and look for a serial nummber. Dlane, thanks for posting the picture cause now I have a better idea what mine is. jrh
