Anthony Lindsey Posted March 18, 2022 Share Posted March 18, 2022 Anyone making the oscillating gear? Quote Link to comment Share on other sites More sharing options...
Korey Kreitman Posted March 18, 2022 Share Posted March 18, 2022 If someone would supply me with a decent gear/gears, I would draw them up in Solidworks. Then they can be printed on a powdered metal laser printer. I’m not sure which one breaks or if it’s both. Anyway, I would be willing to do that. 2 Quote Link to comment Share on other sites More sharing options...
Anthony Lindsey Posted March 18, 2022 Author Share Posted March 18, 2022 Ok, I have one coming and not sure if gears are any good in it. I'll report back once it arrives. Quote Link to comment Share on other sites More sharing options...
Korey Kreitman Posted March 18, 2022 Share Posted March 18, 2022 I had a nice one in original working condition, just couldn’t justify taking it apart to draw the gears. Let me know. Quote Link to comment Share on other sites More sharing options...
Anthony Lindsey Posted March 18, 2022 Author Share Posted March 18, 2022 will do. it will be a couple weeks. Quote Link to comment Share on other sites More sharing options...
Anthony Lindsey Posted April 4, 2022 Author Share Posted April 4, 2022 Took apart the collar oscillator and it is the small brass gear in the nose that meshes with the rotor gear that is stripped. The gears in the neck are in good shape. It was all gummed up and stuck so once I cleaned everything and got it spinning I reassembled it to see if it would work but it doesn't so I will disassemble it again and get some pictures.

Hi Korey, I'd definitely buy a set of nose gears if you were to make them. Thanks Vic Quote Link to comment Share on other sites More sharing options...
Anthony Lindsey Posted April 4, 2022 Author Share Posted April 4, 2022 Here are pictures of neck and nose gear. Nose gear is stripped to nothing. Korey is this enough to scan? Quote Link to comment Share on other sites More sharing options...

Korey Kreitman Posted April 4, 2022 Share Posted April 4, 2022 The brass worm driven gear is the one that’s tough to make. I would have to have the whole assembly to make sure everything is correct. The laser printer is out of commission currently. My friend said the tech has to replace the laser. I can at least get the parts drawn up in Solidworks. I see this getting pretty expensive, just a heads up. Hopefully the rest of the fan is in good condition. Quote Link to comment Share on other sites More sharing options...
Jeff Whitfield Posted April 5, 2022 Share Posted April 5, 2022 Lucas Beshara devised a way to rebuild collar oscillators and was active with it for a while. Not sure if he's still doing it. I've always heard that a collar oscillator and a GE Coin Op fan had the same motor. It might be worth contacting the folks who know GE Coin Ops if they can offer assistance.

Larry Miceli Posted April 7, 2022 Share Posted April 7, 2022 KIm Frank may know. The Collar Oscillator uses the same stator, but I don't know if the gears are the same. Lucas Beshara made new steel gears for mine, but not the nose gear. A few years back there was a run of replacement gear housings and worm gears, but they were pricey! Send Lucas a PM. He may have some used parts. Quote Link to comment Share on other sites More sharing options...

Anthony Lindsey Posted May 11, 2022 Author Share Posted May 11, 2022 Managed to get this back together and it's working. Is there a way to adjust the oscillation? It seems to work its way to the right side. 1 Quote Link to comment Share on other sites More sharing options...
David Kilnapp Posted May 11, 2022 Share Posted May 11, 2022 Nice job! I like the brass on the collar too. My 12" has the brass polished and my 16" does not. Not sure which I like better. If you like, you can get the cord minder from Ted Kaczor (if he has any left) Quote Link to comment Share on other sites More sharing options...

Really nice quality. Quote Link to comment Share on other sites More sharing options...
David Kilnapp Posted May 11, 2022 Share Posted May 11, 2022 Darryl may have made them at one time (good guy) but I don't believe he does now. I got mine from Ted (also a good guy). Quote Link to comment Share on other sites More sharing options...
Anthony Lindsey Posted May 11, 2022 Author Share Posted May 11, 2022 Thanks David, Both look very nice. I skimped out on trying to paint the tag, haven't mastered that yet. I will check on the keeper, thanks. Do you know if there is any adjusting the sweep of the oscillator? Quote Link to comment Share on other sites More sharing options...

I would love to own a set. Quote Link to comment Share on other sites More sharing options...
Korey Kreitman Posted July 21, 2022 Share Posted July 21, 2022 At this point, the cost to reproduce gears is far too expensive. I have decided not to take this on. Quote Link to comment Share on other sites More sharing options...

Louis Luu Posted July 21, 2022 Share Posted July 21, 2022 I got a hold of Geoff Dunaway and he tells me he has some gears stashed somewhere and will look for them. As soon as I get my hands on them, I will begin the tedious process of drawing them up. 2 Quote Link to comment Share on other sites More sharing options...
Louis Luu Posted July 31, 2022 Share Posted July 31, 2022 Geoff Dunaway dug out the gears and will be sending it to me. Quote Link to comment Share on other sites More sharing options...
Lane Shirey Posted July 31, 2022 Share Posted July 31, 2022 As I recall Lucas was using gears from an RC Car. They were already the same size/ teeth and he just modified them. Quote Link to comment Share on other sites More sharing options...

They were already the same size/ teeth and he just modified them. I don't have the machining ability to modify them so it will probably easier to just have it printed. I will get a better idea when the parts arrive from Geoff. I will most likely do a batch print to save money. As for printing cost, there are ways to "trick" the computer into calculating for a cheaper cost. Cost is dependent on size and number of parts. Lets say it is a small piece, the computer already sets a base price no matter what the size is. I can put a "link" connecting these small parts and the computer will calculate as a single piece. I've done this before to save on some Webley bumper parts. After I receive them, I simply cut off the link and a little filing takes care of the rough ends. The stainless steel printing is much cheaper than brass...brass is at least 4 to 5x more expensive than printed stainless steel. The cost will eventually go down as with most technology and early adoption. This is still in the early stages. Now for the stainless steel, there are two types. One would wonder why? If you read the specs, one has magnetic property and the other does not. When I ordered Bobby's Diehl badge, I chose the magnetic steel. I want to see how strong a magnetic field it can generate. If the magnetic field is strong enough, I can use the material to print the DeMott motor. At this point, the materials being used is still in its early stage and I need to try them out before deciding which directions to go for making some prototypes. Also, every time I order a metal type, I keep track of the shrinkage so I have it for reference. As for the cost of the gear, it should be comparable to one being CNC or even less. The goal is to have these parts made on the go whenever you need them. Quote Link to comment Share on other sites More sharing options...
