I'm working on a Westinghouse oscillator with micarta blades. Part of the appeal to me is the refurb...rewire, dusting, etc. I am also not a fan of AC. My questions:
1 - Is there no printed information on dismantling of fans, either member generated, or manufacturer? I understand this is specific by type, and likely by style.
2 - Is there a list of rewinders around, or at least folks that will clean up motors and reestablish the wire from the winding to the switch. Personally, I can grasp mechanics when I see it, but I can't see electricity(until I see stars!)
I am not trying to take work from the folks who restore fans for a livelihood, but hoping that there is some information to be shared to assist in the preservation of these fine machines.
TIA, and I look forward to having someting to show off.

Well, a Westinghouse mikarta oscillator could be a lot of things... does it have an "s" wire guard or a more modern looking one? Are the blades skinny or overlapping? Posting a picture of the fan would be a HUGE help as it would also tell us how you should disassemble the fan. There are several places that you can get your motor rewound but it's best to first see if it really needs to be done as a rewind can be expensive.

At this point, it would be multiple pictures, as my inability/fear of taking it apart prompted my questions, though have been lurking for a while.
It (are fans gendered?) is a 4-bladed (12" span), S wire cage, style 516860 s/n 6389876, black (a la Henry Ford), with a big knurled oscillator knob on the back .
My current concern is the removal of the front & back housings which hold the shaft. There are 4 screws, but from that point, is it a twister or a dead blow hammer? Two pics attached.
The other aspect is the electrical, and bluntly, the unit runs well. So after cleaning the aramature, I would like the confidence to rewire the wound part; so removal of the windings is likely next.
Thanks for not laughing, at least not openly, and I apolgize for only giving 'hints' as information.

I don't want to load you down with technical terms already, but "rotor" is the term you want to use, not armature. "Armature" is used when you are talking about a brushed motor. The name for the stator in that case will be "field windings" or "field coils".
Back to your Westy... there is no rear end bell - the four screws you see will only remove the oscillator and rear bearing. If it runs well, then why do you want to mess with the windings? If you do, it is not going to be easy as Westy stamped steel fans have the hardest to remove stator of all! You'll have to refer to someone else to help you with that.
BTW. where is your other pic? You will need to reply to your topic and attach another pic there.

| You most certainly do not want to rewind the stator if it is running. Taking the stator out of these stamped steel Westies can be a real challenge. To use your term, they are drop hammers. It is easy to ruin the case with too much drop hammering. I speak from experience. If you don't need to take the stator out, don't!

I'm with Doug here. I just finished putting a headwire on a stamped steel Westy for the old battleship because the old one was broken. It took me almost all day to replace the headwire & then half of another day getting the case bent to the exact point where the bearings don't bind. My recommendation is shrink wrap the old headwire if the outer coating is questionable & reuse it. Westy headwires are the worst!

It comes late in life but i have let my better judgement rule, the stator has not moved and will not. So the rotor is out, and am perplexed by the the two bells that I was driving to remove. Each, as mentioned has 4 set screws.
My motivation for removing the bells comes from the 1941 Hunter Century I did first. The grease(yellow) in the oscillator had dripped out over time, caked up, and made a mess over the body. I enjoyed removing that part, cleaning it and getting it to run smoothly. I had also removed the front bell there, and repacked it.
Here the front bell has what would appear to be a forerunner of a zirk grease fitting, which is off kilter.
This, the second picture, is the front bell, from the inside.
So with the stator staying in place, my remaining concern is cleaning it and re-cording it...the old rubber wire is cracking.
TVM to you and Doug, my welcome here has been both instructive and engaging.

I can't say that I don't look for trouble on occasion, but I'll pass on electrictity.
You suggest using a heat shrink tube around the head wire?
Thanks
