Henry, they look great so I shall relent and purchase one for my 12" Fidelity oscillator which is missing just the worm.   I understand that I need a matched set so that it will be.   Please post or pm purchasing info.   I can pay with PayPal family/friends.  Sorry for my indecision early on about buying the gears.

My large gear does have the small hole near its hub for oil transfer.

Here's a set Henry made, installed on my open gear that was missing the worm and the wheel had about a 30 degree arc worn out.  Works like a champ now, and almost scary oscillation on 110 V DC and high speed.  Whips around fast thru the first arc, then goes nuts on the return.  I haven't figured out why, but the arms give different speeds in the two directions.  But the gears don't complain, they're completely quiet and the best looking part of this old fan.  Not that any open gear is going to win first place at the County Fair.  Thanks Henry!  Here's a couple of pics:

  I can vouch for the quality of those gears. I put 2 of those old fans back into daily runner status with new gear sets & they work very well.  :up: :up: :up:

Thanks for the nice comment Geoff. Is the backlash OK, not too tight or loose? Still trying to get a better handle on the consistency of Fidelity's machining of the shaft center distances.

  Paul checked that right off the bat. One of the fans had great backlash the other was a snug fit but after running for a couple of hours was a perfect fit and quiet runner. The worm that yours replaced had taken on a "V" profile where the allignment collar on the osc. shaft had slipped. The round interfacing gear was toothless in one spot like my 5 y/o grandson.

Jim, If your using a full wave bridge rectifier try replacing it with a diode or half wave rectifier.  It should cut your fan motor RPM by roughly 700 RPM.

Russ, yep, I've used the half wave, or just cut the input voltage to the full wave, but I was wondering about an apparent difference in the speed of oscillation going right (fan right) versus going left.  I can't seem to get my mind around why there would be a difference, but it must be something in the angularity of the lever arms (including the stationary arm, I think).  Or maybe it's purely my imagination...Jim

Mine does the same thing, goes slow one direction, whips back the other. Goofy to watch for sure.

Just like fly casting; out fast and back slowly.

I don't have one to study. How the Stauffer boys got away with pouring all that iron for decades on end, h ell if I know?  :wondering:


You aren't imagining anything.  I watched one of those geared boat anchors oscillating in hyper drive in the past.  I sucked at algerabra, triggeranaumatry, and geograpghicanomitry. So which one of them there physic applications is making the cast arm push the cast link insy outsy faster.... h ell if I know. :gears :tumbs

I bought a set of gears for my 12" Fidelity oscillator from Henry and they arrived in no time.  Some fitting was needed to get the worm gear on the shaft; I had to dress the shaft down some and, then, it fit perfectly.  Adjusted the gears (I only used the worm gear for now with the original big gear) and the old fan ran and oscillated great.  I expected a somewhat crude oscillation but I'll have to say that it is a good oscillator with interesting motion.  Not much lag at the end of the oscillation; a real smooth old fan.  Thanks Henry for making these gears.
