I just powered up this Menominee Clamshell for the first time. One of the brushes is missing, so one side is running on a spring. Before powering it on, I took it apart, resurfaced the commutator, oiled it up, and made sure it spun smoothly. I also tested the resistance between each plug prong and the corresponding brush holder, and both sides read 44 ohms. I powered it up and it vibrates and buzzes a ton. Here's a video of it.

If the embed code above doesn't work, here is the link to the video:

After this video, I figured out that the front bearing was a little loose, so I tightened up the screw, but it still sounds pretty much the same. I will update with the video I took after tightening the bearing when I get more time.

Can anyone tell me what the source of this sound is? Bad bearings? Also, when the fan is making all that racket, the shaft is spinning very fast; it isn't just sitting there buzzing.

Any help would be greatly appreciated!

Edit: I figured out how to embed the video!
