I was searching through old posts last night and came across a gem.  Pictured below is a collar oscillator gearset. So the question is...  
Did anyone post a detailed sketch of theses, or is one out there somewhere?  
Does anyone know the person who made them and if he is still around?

I emailed the person who was named as making them and hope he replies. If not does anyone else have any to model?  Any info is appreciated. I've got all the tools to make them now but a gear hob/cutter that fits. The biggest question is the gear pitch, and is the 12&16" stuff interchangeable?

Thanks!

I guess I should illaborate a little further on this. 
I have a 16" collar oscillator and it was missing the link and the lower pinion gear. All it had was some broken pieces rattling around in there. I have already made a blank for the pinion gear that attaches to the link. I just need to cut the teeth. I've been buying gear cutting hobs but would like some input on what size I need. There are a ton of different sizes and I am shooting in the dark. 

Also with the link missing I don't have anything to model.  I'd have to measure with the nose on the fan, but that's kind of impossible. So if anyone has a 16" collar oscillator they'd take apart to measure I'd be in your debt. I have a 12" to model, but with the different motor sizes I'm almost sure the links would be different sizes. 

Anyhow I did get some offline responses and their seems to be interest in making these gear sets. I'm willing to make them and have all the tools to do it. Just need someone to measure the link. I know the lower pinion gear was permanently affixed by a through pin that would need to be destroyed to remove it and the lower pinion gear. I already have a few replacements made for that part. I'm sure no one wants to take their working fan apart to possible damage these potmetal gears. But if your fan is already broken what do you have to lose?  I'll send you a new pin to replace the old one. Again any help is appreciated:up:

        Lucas,    Have you had luck getting assistance? And have you learned about or confirmed possible differences between 12-inch and 16-inch collar fans? I know the motors, the bases and the brass collars are different diameters...   I should be able to participate if no one else can answer you, but it would be another week before I'd be able... and if another member has answered the call, you'll get a more prompt result.
    Also, could you clarify using the diagram? I had assumed you were referring to the segmented gear G, pinned to the Link F... but the lower pinion would be D, and the link is attached to disk wheel E... or is it bevel gear H??
   I'm glad you're taking on this project... anything else of note with your fan?

Good clarification with the picture Steve!
Yes the big question is with link F and gear G.  Are they the same between both 12" & 16" models?  The pins I pictured hold gear G permanently to the motor housing. It is inserted and peened to never come out. I ground off the bent tip to get the pin out. Have a few replacements now. This would have to be done to get accurate measurements of both gear G and link F...  Both of witch are missing on my fan. 

Bevel gear H is easily removed and can be dimensionally checked against the 12" & 16" models. 


I'd be willing to make both 12 and 16" replacement parts. As I have a request already to make a 12" gear and need a 16" piece myself. I'll have a chance to model a 12" gear and link in the near future. I'll post a detailed sketch when that comes to fruition.  With those dimentions I can also check gear H and make some assumptions on gear G for 12-16" differences

Made some good progress on my gearset this weekend. My 16" was missing the link gear and both pins that held the link on. So I'm muddling through and working from the gear in the neck back up...  found a gear that meshed and I was off to the races:clap:





















I've got to order some link material or I could have gone a little further. 


Those of you who inquired about me making multiple sets, I'll let you know how it turns out. :D

Making a couple upgrades before final assembly. I tested the front bearing and the shaft was rattling around in the nose. Being a 16" 6 wing and no way to lube or oil this fan I kinda figured it would be sloppy. So I drilled out the nose taking John Fengel's advice for drilling these pot metal devices. Step up one size at a time between fractional and alphabetic drill sizes and go slow. It worked out very well:up:  I'll be making a grease cup for this new front bushing...:D  lube for the front of this fan which it never had before

I don't know how to describe obscenity, but I know it when I see it.

I mean that in the most complimentary way possible.

Update. I finished the fan and ran it a while without the blade and all seemed good...  had to fix a broken wire in the cage so I waited to run it with the blade due to the wife being strict about no cage fans running. Made a new wire and I was off. Ran it for a while stationary and the thing ran awesome. It pulled .7 amps without the blade and .9 with. No wine, hum, or stator hop. Put the cage on and went to oscillate...  it was rough. Kinda hopped through the teeth. It worked but in not quite there yet. Gonna break it back down and see which gear was the issue. I tried to get away with using the stock pot metal gear 'H' and I prob should have just made both. Anyway. Lesson learned. This is gonna be a sweet running fan when it's done though!

Update. It was the teeth on gear H that were too tall to let the new bevel gear fully seat. I shaved them down and it is now smooth as silk!  So I can fix them on the 16" motors.  And I may have a 12" coming into my possession where I can start making the 12" stuff also. Love the kinship of this group:up: 
Hard to see from the pics but the new gear was riding on the peaks of 'H'




After cutting down the original they mesh perfectly. Couldn't get the light quite right but it certainly worked out:clap:

Made some good progress today for helping all 12" collar oscillator/non-oscillator owners.  Big thanks to Carl Parker who let me use a fan to measure all the parts from one he had!  Soon I will be able to make them for both models...
The big surprise it that both models use the same gear set. The motors are different and the brass collars are different diameters. But thankfully they used the same potmetal gears, meaning I can make them both for 12 and 16" models.

I decided to remove the slop from the pinned link also. Rather than have a pin with a cotter I decided to have a threaded pin that locks into the lower gear. The slop present in a complete assembly wasn't acceptable to me. My 16" had it and the factory 12" had it. So upgrade!  I'll be working through this assembly. Just an update

Wow! This is awesome! 
As a GE Collar Owner with missing parts I am very excited 
by your work. 
Hope for us who do not have your skills. 
Keep up the good work. 
Looking forward to buying parts.

Lucas, you just raised the eBay price for :wondering:"untested" :wondering: collar oscillators by about 50%!

Lol!  Thanks for the interest guys. I know when I first saw this fan I fell in love. Such engineering to have a magical and elegant way to oscillate. I've got a bunch of money in machinery and r&d for this project, but the real price tag will come from my labor. Its a pretty intensive process and consumes my weekend plus some with making it perfect and tight. If a bushing turn out loose I'm making another one, if something is tight I pull a file, etc. So if I charge $300 bucks for my weekend don't get upset. I charge $50 bucks an hour to sit my butt in my tractor. Lol. And I'd need you guys to send me your non oscillator and I'll fix it up and get it back to you.  And naturally you'd pay shipping back and fourth. 
This is prob my favorite GE and if you're like me you want a perfectly operating fan with no slop, hop, chatter, etc. that's what I'm doing on these fans. Make them like the engineers wanted...  perfect. I'm almost done with my 12" and I'll let you know how it goes :up:  

PS I want the eBay not tried collar oscillator fans

But now that people know they can get replacement parts from you for the most common failure on these fans, they'll be willing to pay more for the "untested" or for sure broke collar fans (perhaps).  You may have become your own assassin when it comes to buying relatively cheap collar oscillators!  But I'm just kidding around here, it's absolutely great you've done this fine work, and I'll be looking for another collar oscillator in the future, try to make the wife even prouder of me!

So my upgraded assembly turned out to operate flawlessly! (After disassembling and reassembling several times over to shave this or touch up that). This isn't an assembly line or CNC operation after all. Lol
I threaded the hole it the gear and made a threaded pin. Then shaved a nut down to fit in the tight little space there. Finally when the assemble was in operating condition I superglued the nut on. This will eliminate all the down falls of a cotter pin type connector. 










Why they decided to run the head wire out the front with a rotating assembly right beside it is a mystery. 







Anyway I'll be offering this service to the public. I'm still working out how to price it but starting at $300 will be the lowest cost option for a cleaned and disassembled stump. If I have to disassemble a fan with 100 years of grime and do the electrical and servicing it will be more. Just trying to get my parts and labor in line

I'd like to say it's priceless to have this beautiful piece of history operating flawlessly but that's in the eye of the beholder. 

Big thanks to Jamie Williams for helping this fan find its way to me!
