The top dial is for the cross slide on my 1941 South Bend lathe. The bottom one is for the compound. If you look close, you can see they are different scales. The cross slide feed screw was changed from the factory 10 threads per inch with an indirect reading dial, to an 8 thread per inch screw with an direct reading dial. For the cross slide, the direct reading dial is a little easier to work with. For every turn of the handle, the tool moves in 0.125 inches, but would REMOVE 0.250 inches off the diameter. You would rarely, if ever, measure the RADIUS of the part you are turning, so this configuration makes the math much easier.⁠

Picked up this 80 year old copy of the Machinery’s Handbook.

Picked up this 80 year old copy of the Machinery’s Handbook. This has charts, data, and specifications on just about anything you would need to make on a lathe or other machines. Things like how deep the threads for a 1-7/8″-8 spindle would be. A must have for any budding machinist. And I specifically wanted an edition as old as my lathe, for nostalgia more than anything.⁠

You never realize how useful a 3D printer can be until you have a 3D printer.

You never realize how useful a 3D printer can be until you have a 3D printer. The tailstock for my 1941 South Bend lathe did not have way wipers on it. The way wiper clears away junk on the ways (where the tailstock slides) preventing that junk from getting under it and damaging the ways. So I drew up and made a set of way wiper covers that I will mount on the tailstock with machine screws. I even incorporated some oil passageways to occasionally add more way oil.⁠
