I received a request to reproduce a Manhattan fan cage using a sample. When I opened the box, I was met with a real problem. The center piece was a stamped ring instead of a solid ring. I don't have a punch press and tooling to make these, so If I couldn't figure out a way to fab this up, I would have to return the cage and not accept this project. Searching around my toolbox, I found a huge tube socket for the sprocket nut on one of my bikes. It was the right size. I rounded the end of it on my belt sander and radiused the inside with my moto tool. Taking some sheet brass, I measured it up and cut it to size. Using hammer and dolly method, I folded the edges around the tube socket, stopping to frequently anneal the brass so it wouldn't crack and split. At this point I used my drill press to push the center through inside the tube socket. Now I had something that would work. Success. I saved the project. The rest is just like any other cage, with rings and spokes. Cheers, Bill7 points

Here is one Reynolds George wishes he had. 🙂 I don't know who got this example, but someone did. I would love to know if there is a patent stamping on the blade somewhere. James Funk engineered and patented one of his last blades to Reynolds in 42 before his death at 48 years. This blade has similar styling to his design.2 points

Finished up restoring this all brass. It runs in three distinct speeds. Circa 1911. No painting on this one. I sent the whole motor too Mark Olsen to have the stator rewound. He discovered that the rotor shaft had to be replaced and align the bearings. Mark did an awesome job! I can't thank him enough. The fan runs quiet and smooth. This is my second all brass fan. The other is an 8" Western Electric.1 point

It’s finally here, safe and sound. The Old Forum is preserved for posterity! Special thanks to Larry, Jamie, Stan and the board for making this a reality!! I was happy to play a small part in this opportunity.1 point

You'll need to slow that a bit, 3350 is pretty darn fast. That said, I remember that motor on eBay. It was a beaut....1 point

Well, Stan, I have a 6 pole 2104 now. 🙂 Taking the stator out on the R&M 2404 and 2104 was not bad at all. I just drilled two opposing holes in the housing out to 1/4", rested the housing edges on a bench vice, and drove the stators out with a 1/4" drift punch. After carefully wire wheeling the outside of the stator laminations clean, and wire wheeling with a handheld drill the inside of the housing where the stator inserts. I was able to slide the stator into place with hand pressure. Here are my modifications to transplant the 4 wing 5204 6 pole stator, rotor, and switch into the sick 6 wing 2104 and get her up and running again. As previously stated, the list 5204 switch bolted right on to the 2104 base plate no modifications.1 point

So I rewound the stator with all 28 gauge wire. I did 700 turns then a tap and 150 turns and another tap with 150 turns. I went a little overboard with a total of 1000 turns. It worked a bit too well. The fan would not start by itself but if I turned the blade it would run. It was slow and just a small breeze. Perfect but I hated the idea that it could not start itself so I redid the entire stator. Unwrapped it and took out 200 loops and resoldered it. Works great. Starts strong but turns pretty slow on the slowest speed. So looks like 800 turns is the sweet spot if you want a desk top fan that will not blow everything in the office around.1 point
