Restoring the Queen City 12 in grinder

[invisabledog]

Since I had to tear down the recently aquired Queen City grinder, to see about rewiring it to 220v, I thought I'd clean it up and repaint. The blue paint must have been sprayed on to make it look good for sale at some point. They sprayed everything, even over the 1/4 inch of grinding swarf on the base of the pedestal. They also got some on the wheels. The wheels appear to be near new and not used since the paint job. Blue paint is on the faces of both. I cleaned up the pedestal, motor mount and both motor bells. The windings are at the motor shop. It will be painted osha safety green when it goes back together. That's the closest match I could find to the original color, without a custom mix.

I think that's going to be really nice when it's done. I'm glad to see that rewinding is a feasible solution to getting it to run on 220V. Looking forward to seeing the finished result.

Making some headway. Got some paint on the base. Still waiting for the windings to be done.

Holy Smoke! That is a nice grinder!

Looking forward to see it finished! Good Luck!

Going to combine all my queen city grinder stuff into this thread, since it all falls under restoration, now. Got the base and switch painted and temporarily mounted the switch. Also got the windings back from the motor shop. I now have a modern 9 wire 220/440 3ph winding. Today I hope to get the new bearings installed and the end bells back on. Maybe even some paint.

That will make a fine,powerful grinder. The windings are dipped. I don't know of any Asian motors that have dipped windings. They sometimes short out because of that.

The shop does quality work. Started by a vet when he came back fom Viet Nam. Logically called it G.I. Electric. Not sure if it's still the same family.

It's starting to look like a grinder again. I did run into a bit of trouble. After fixing a crack I found, I painted the left guard. After painting it, several more cracks showed up that I didn't see before paint. This guard has a lot of old repairs. I'm going to try to repair it, but am getting a bit leary of it. Would love to find a good used one. Can't really afford to have a new one cast after putting a lot of money in the motor rewind.

I like your color choice...kind of grows on you and reminds me of old equipment seen in many old shops. Nice job on the resto.

Good news and bad. I repaired the guard and got it installed, that's good. The repairs failed, catastrophically. This thing is basically shattered. The pic is the worst of it. There are many fine cracks radiating out from the large ones, worse on the inside where the paint isn't hiding anything. This guard was extensively repaired in the past I preheated and slow cooled, but to no avail. This guard is now scrap. So if anyone knows of one, let me know.
