Friends:  The restoration of this kidney bowl is completed. Some before and after photos below. Many thanks to Lane Shirey for sharing with me how to use automotive touch up paint with some 1200 - 2000 grit sandpaper to make the big paint chips almost invisible. I'm still learning that technique but it makes a big difference.
Before:







After:







I was nearly finished a week ago when I ran into a problem. I installed the switch and turned it on whereupon it immediately blew a circuit breaker. I guessed that there was a break in one of the head wires where it connected to the coil and so I covered them with shrink wrap and reconnected it. This time, it didn't blow the circuit but the fan did not work and the coil got very hot and began to smoke. I thought that I had burned up the speed coil (wrong) so my good friend Dennis LeBow supplied me with another coil from the same fan. A week later, I hooked it up and same result with a hot speed coil. At that point I was scratching my head. I got good ohm meter readings on all three wires so I figured I must have a short up near the stator, which I removed. I unwrapped the three head wires, cut them back to within an inch of the stator and removed the crumbly insulation. Then I covered them with shrink wrap and cleaned the ends with a knife so I could get a good clean soldered joint with some new three conductor wire. Put it all back together and voila, it fired right up without a problem. I wish I could have saved the original wire but it was not to be. Of course, now I have a second GE speed coil which is now cleaned and polished and in my inventory (if anyone needs it, I'll gladly sell it for what it cost me plus shipping - $50). Another lesson learned in my restoration journey.

Looks great! Love the GE kidneys. Hope I can find a good one someday.
Could we get a video of it running?

I would love to post a video (if I only knew how). I'm off to choir practice (tomorrow is the Christmas cantata) after which I will ask my daughter how to do this (unless someone can enlighten me here with a step by step method?)

David,


Your ohm meter is your greatest friend.  The last thing I do before plugging in a fan I've just finished horsing around with is check ohms across the two prongs of the power plug with the speed coil set to OFF.  Should see infinite ohms.  Then read the ohms across the prongs as you move the speed setting through low to high.  You should see the combined ohms of the speed coil and the stator on each setting, and never see zero ohms (the ohms will vary on each setting because more or less of the speed coil winding is being checked).  Then check from a power plug prong to bare metal on the fan, just to be sure nothing is shorted (0 ohms) to the fan case/base, which would leave voltage on the fan metal parts whenever the fan is plugged in.  There are some other variables like resistance wire in the speed control versus a wound speed control (choke coil) that will affect what readings you see, but the biggest thing is that you never want to see 0 ohms.  That 0 ohms is what lets the magic smoke out of the fan.  You also don't want to see infinite ohms, because that generally means the fan isn't going to run, but at least you won't see smoke or flames.

Thanks Sean. I bought the GE Sidewinder that JDL-fanman sold. I probably over paid at $960 and the description says that it doesn't oscillate so there is some issue with the gears that I will have to sort out. But I love to work on these old fans so price isn't a huge obstacle. I expect that fan tomorrow by FEDEX

Did I mention I'm in love with that Kidney bowl Oscillator? :D


That video....looks like a salesman in the early 1900s was demonstrating a brand new fan! Seems to be a good touch smoother in operation than the later AOU(though I know the Kidney was a much more expensive fan back then). :)

GE's are so easy to work on. Thanks for all the kind words! I appreciate it.

Very nice! Can’t believe how well it runs. Well done!
