Thread: War Depatment Bridgeport
Started 2 months ago by ogesII
A neighbor of mine has an old M-head Bridgeport with USWD stamped on the table along with some numbers. He says it was a war dept machine. Anyhow it doesn't run due to a bad motor and he wants $200 for it with a SS phase converter. The machine isn't rusty, scratched or dinged beyond what would look normal. And everything moves easily. I'm sure the 1/2 hp m-head would be enough for ...

Thanks jmelson, Based on your comments and what I've been reading I think I will pass on it. $200 is just so tempting for getting into a mill but the J heads and R8s sound much better. It sounds like buying a machine that you can't hear run is risky. Especially if the M-heads are undersized. I thought the USWD part gave it some nice character also. But I'd rather have a mill that ...

Is there an easy way to tell what quill it has? Is it stamped somewhere? Or is there a dim I can take? I guess if I could pick up a J-head for $200 it would be worthwhile. I'm not seeing much for working mills in the classifieds for less than $1500. Of course I have no idea what a j-head would end up costing me either.

HAH! So it is still good! Well, a reversing switch will be a lot easier to find than an exact-fit motor. One problem I had was the stock motor was very weak running on a static phase converter, IE. single-phase running. I could stall it with my hand. It ran much better on a VFD. Oh boy! Do those pictures bring back memories, with that odd little &quot;hat&quot; on top of the motor. (Yes, I know, it is to keep things from falling or...
