Can you even imagine how excrementally boring it would be to run that lathe? No feeds, carbon steel tooling... it would take all day to take a cut, and you'd be turning that handwheel the whole time. Wretched.

Geez. I imagine it would rust up again before you finished the cut. http://bbs.homeshopmachinist.net//wink.gif

Unless there is a keyway in the leadscrew that is hidden in behind, I don't see any source of power for a feed. Mind you, they might be able to use the leadscrew itself as a feed for finishing cuts.

If there's no feeds then how does he turn the handwheel from where he's standing?

Oh wait I just figured it out, must have a happy wife. http://bbs.homeshopmachinist.net//biggrin.gif http://bbs.homeshopmachinist.net//biggrin.gif

If I'm not mistaken the handlewheel for the cross feed has been removed. It must be running on power. Compound handle is gone too. Talk about old and blind http://bbs.homeshopmachinist.net//biggrin.gif

Probably took it off so it wouldn't wind up the chips.

Dave, the turner could have a happy wife but i think that he is left handed and could have been self employed when this shot was taken. There appears to be a steady supporting that big mother while the operater controls the machining operation by telepathy (they had some strong willed men back then before new age men arrived)

I hate to break it to you,but many lathes have a keway milled in the leadscrew,the seperate feed rods didn't come in until after WWII from what I have seen.Plus I like the system,it drives everything from the one shaft,and many times both feeds can be engaged at the same time,like on the Hendey machines from 1920-1950.

Separate feed rods have been around since long before WWII. Story goes that some manufactures felt that the slot in the lead screw warped it, an incorporated a feed rod. I've seen and used both systems, couldn't tell any difference.
Take a look at the cross and compound screw ends, they're square for crank handle.
