An old early 20th century Buffalo Forge hand cranked drill press. I removed the rust and cleaned it but didn't do any more restoration than that and re lubricating it.
I also machined a chuck mount and chuck to fit into the original Sliver and Deming style chuck. This drill does work... but slowly. It is self plunging.

Brad, thanks for your thoughts.

Not a tool per se, but a motor for one. Early 20th century repulsion-start, induction-run made by Century. It's in line for restoration, but I don't know if I'll ever get to it. Too many other things demanding my time. Runs fine, though it's a bit rough looking.
Kinda big for 1 hp, compared to the 1 hp Baldor sitting next to it.

SWEET ! You have got to love Walker Turner machines.

Restored this a few years ago and have been adding little extras over the years. Nicknamed the drill press of death.

Hey Tom....What is it about this repulsion-start induction-run that makes it desirable? How was it better?

Hey, a Boice-Crane Helmet Head drill press! Literally, that was their name. Not many around, I got one once, single most hideous machine I've ever had. No offense, 2Beast, that's a nice looking one. Nothing like the one I was given.
They are seriously heavy 15" machines.

They are (relatively) high starting torque motors, with relatively low current for what they output, when capacitor-start hadn't yet been invented. DC was also common then, and they have similar torque characteristics. You could buy a Unisaw with a DC motor up into the 50's or 60's, in fact, and the RI motors were common up to then, too. So it's just yesterday's equivalent to cap-start, more or less.
But with the wire-wound rotor and brush system, they're expensive. And complicated. No wonder split-phase and cap-start (though cap-start is technically split-phase) motors took over. And 3-phase, the simplest of all of them, with just one moving part.
