Help!
Ok, I put money down on a Bridgeport Mill, SN: 131234 (on the front end of the area between the ways above the crank that moves the bed front/back... missing the MOTOR!! But relatively inexpensive, and local... so far good.
Has a really old Anilam DRO, condition unknown just yet. (anyone know where I can get schematics, if I need them?)
But the HEAD has a vari-speed dial on it, the readout is in front on a dial... the sides are enclosed.
What head do I have here??
The head looks pretty much like this one:

Oh oh! Part of the varispeed drive is ON the motor! There is a pulley with a sliding flange coaxial to the spindle. That flange is moved by the vari-speed crank. The motor has a spring-loaded flange that keeps the belt tight. If somebody just pulled the whole motor out, then that rear pulley went with it. You can certainly get a motor and pulley set from somebody who has torn one down, but it won't go cheap!

One easy solution is to simply buy another Bridgeport mill head. I'm going to have a clean step-pulley J-head available shortly. It was fully rebuilt about 4 years ago and has had very light hobby use since. Of course, it isn't varispeed, but then it's clean, complete, solid, quiet and WORKS.

Hey Grant,
If BEAR doesn't jump at that, lemme know when, where, and how much. Mine is starting to rattle more than I like.
Take care.

If you need a motor anyway and if part of the varispeed is missing, would it not make sense to simply scrap the varispeed and install an inverter duty motor and inverter drive?

Yes. Which is one of the reasons I like the 1J head better. No clanking as the varispeed pully bushings fail and eat up the motor shaft, etc etc.
Putting a decent 3hp VFD on a miller is a marvelous thing to do, and makes it a hell of a lot more versitile..AND allows you to run it on single phase too.
