Nasty electric motor

It is indeed. I had a 5 hp drip proof given to me years ago because it was locked up. Guy said it had set out in the weather and the bearing froze.

I pulled the end bells only to find good bearing just like you. But the mud daubers had glued the armature to the coils. I just kept it wet for a few hours blasted it out with a garden hose.

OK, my smirk: Was at a tent sale of returns from Northern Hydraulics.

2hp TEFC motor, brand new at (TA DA!!) $.50, (yep, half a buck). Bought it >> Today, I got a chance to save the machine I need to repair or make a shaft

I saw this very same repair procedure described as: percussive maintenance, recently.

Did that with an electric drill after it had been dropped off the step ladder. Gerry :-)} London, Canada

Speaking of electric drills, while screwing down drywall for my machine room, my cordless drill quit charging. A quick google found that the charger for this drill is flaky. I have the battery pack attached to my variable voltage / current limited bench power supply atm. Wonders of wonders, the drill is fine, the charger is dead.

I really want to use my 14.4 drill since the 18v one is a wrist killer.

this isn't

I take it that you believe you saved the motor by removing all the detritus from the innards? Bueno, bwana.

I put it back together today, didn't hang it back on the lathe. I'm a bit bummed, the shaft I thought I could make another one of is part of a gear / clutch basket made out one piece of metal. Gonna have to weld it. There is a bearing on the shaft that I can't get off non-destructively so I'm holding off until morning. Going to bring in some aluminum foil to wrap it with, didn't feel like watching rags burn.

I did a bit of welding practice on some scrap today. I don't weld that often so wanted to practice a bit.

Obviously this isn't

I got a Bridgeport J head out of a guy's garage. It had been an auxilliary spindle on some kind of huge planing mill, and was still attached to an enormous aluminum dovetail piece. The dovetail was nearly a foot wide.

Anyway, just cleaning the thing up, the motor seemed to spin easily, so I decided the bearings were probably OK, and just put it all back together. As soon as I hit the switch, the motor spun a bit and seized up with a horrble screech. So, I tore it apart. I was totally astounded! The entire inside of the motor was packed with several-inch-long magnesium chips. I was able to fill a small trash can with the chips. I torch tested them, and they were definitely part magnesium, but might have been duralumin or aluminum-magnesium alloy. The bearings were easy to find at the bearing outfit. Amazingly, the motor didn't seem to mind being packed with sharp, combustible chips!
