Hi Every One! I have been thinking about this for a while, Finally did it. Engineered via SWAG! Will here it is. Video.MOV

My work. Old coils and new coils.

Typical Monday....getting some Marelli motors working for a special project, test running a Simplex vane table. It's #2 of 18. #3-5 are in paint. 6 & 7 will be machined this weekend. Some cakes and kidneys awaiting pieces and parts. A C-W armature needing some commutator work.....

Thanks to Bill the Cframe is turned from door stop to a keeper Hopefully Bill's spectacular paint work will distract the eyes from the polish on blades...did the best I could without removing blades ( did not want to mess with solid rivets I can barely do the hollow ones) Only room for one fan there ...that 71666 is going at Fanapalooza March 18

No fans on the workbench presently. A load of pancake cages, though. Cheers, Bill

Ge Smy that I cant to get to run right. Flipped the front bearing but it still struggles to get any kind of rpm. I do beleive I got the wiring right too.

We call that "swing oil" in golf.

Working on a 1901 pancake for a friend...Waiting on some parts from Darryl Hudson and a reproduction motor tag from Don Coleman.

Sadly, my workbench has too much junk on it to work on it at the moment. However, I do have two projects currently in progress. One is a 1950s four-bulb, four foot fluorescent theater light. The other is an unusual 12" GE two star DC I bought years ago. The fan might be left as it is as it appears to have been converted to AC many decades ago.

I expect my work benchs are a bit more cluttered than most, I have 4 or 5 areas, most outside

Are you guys surgeons? Looks clean enough for an operation....very nice

With only one partial project going see my workbench below. I could say I admire you, envy you, or hate you for having such a clean workbench ! I’m considered pretty darn “AR”….but.damn! You beat the heck out of me! <grinning> Don’t have all the parts from this donor fan and am still deciding whether to spend more cash on a resto, or just put the parts lot up for sale.

My Menominee Clamshell was a bit noisy, due to a worn front bearing. I asked Darryl Hudson, our fan bearing and Menominee specialist, if he had replacements, but he said he never had the need. So, I pulled out the bearing and inspected it. Shaft OD: .249” Bearing ID vertically: .264” Bearing ID horizontally: .253” It’s typical to have more wear vertically due to the weight of the rotating assembly. I got this idea to try to crush the bearing smaller, then ream it out, a technique commonly used to repair worn clock bearings. But, I had some precision .249” shaft, so I cut a piece a little shorter (about .03”) than the bearing length, slid the shaft inside the bearing, and crushed it in a small vise: When I was done, the bearing measured .253” ID. I put the bearing back in the fan, and now it runs like new. I assume that only the front and rear of the bearing are properly sized, so the fix may not last 100 years.

I can just hear the gears in Rocky's mind grinding out the thought,... "Can that be done to a Jr.?"

I am currently trying to replace some worn brass/bronze brushes in a 1909 fractional dc motor. I had some success by using a carpet cutting knife for the straight edges on longer cuts, then using a jewelry shear to curve the tips. I tried to hot glue the brass/bronze to a piece of thin balsa , and even a bit of scavenged plastic from a milk carton because the shears would simply bend and deform the thin metal before I could complete the cut. Jewelry saw was tough to learn. Still searching for the magic method to cut and shape such a small and springy piece of electrical contacts. On the subject of salesman’s samples. I have never seen a functional antique miniature motor that was truly a salesman’s sample. I hear the term “salesman’s sample” bandied about by antique dealers when they can’t identify a small functioning item, but I have never seen such a creature in a antique or vintage motor (or fan) and would love to finally see one if anyone has an example. IF Louis’s motor is a miniature functioning model of an old German motor , Germans often copied bigger electrical motors for an authentic feel. Siemens was a popular example. But in my opinion , Louis’s motor was a upper quality tool as a dynamo/motor for schools or labs, or something to use by professional jewelers or tradesman. Not much of a toylike set of components in that motor. BUT that type motor or dynamo would usually employ phosperbronze, or copper gauze, or even a carbon brushes . That simple springy brass brush is weird for keeping tension on the quality commutator. Be interesting when repaired to see what voltage it runs at (or outputs).

You can also rotate the bearing 1/4 turn left or right and drill a new hole on top. The egg-shaped wear is shifted to 9-3 o'clock and strangely enough the fan quiets down. Must be a gravity thing. Not a quality fix, but it makes a difference. 🙂

Please, let's not...

That’s the back switch model.

As the late Paul Harvey would have said,... "And now you know the rest of the story!" So sad, but true.

I have several projects going at the same time in my shop, but the place is NO where near as neat and organized as the OP’s 😉 In the next few weeks, I hope to complete a reboot of an Emerson hassock fan using wood, brass, and artistic license.

I don't think I could use anything you restore unless I used rubber gloves. Working for a motor shop is a big plus on your end. 🙂

Wow that is awesome. That is first class restoration.

Cheryl got it done. So I should now show as a full member.
