My first Lathe. craftsman 101.07403. Restoration process and progress...

Joshua,

Those are the correct dimensions for the L3-109. However, SAE 863 is sintered iron. Sintered bronze would be better for this application.

Thanks for the detailed dates. Did you ever locate the serial number?

Hmmm, I saw "super oilite" and bought it...next time. Where is the serial number? Tail stock end of the bed? If so, it's...12158 s
 
Joshua,

Yes, that would be the serial number. Thanks.

Super Oilite was supposedly developed for low speed conveyer rollers, cart wheels, and the like. It has a significantly higher radial load rating than Oilite. But as I wrote earlier, has a lower maximum recommended SFM than Oilite. The reason for the higher load rating is obvious but I've seen no explanation of why the lower speed rating.

One other thing - I don't believe that you've said what the bed length or distance between centers is. Until 1950/51, the model number did not ID those figures. You had to also know the catalog number. In 1945 the 101.07403 was still being offered in four lengths, 12X18, 24, 30 and 36 (bed lengths 36, 42, 48 and 54).
