50 Yr Old Box Fan - Install New Bushings and Check Motor Windings. 

Yeah, that was an interesting project for me. I'm glad it worked out in the end. Sometimes it's fun to try and fix old things like that; not that there are too many of them around anymore. Lol...

@@ElectronicsEditor I know, while they're rolling out with these cheap, worthless plastic blade box fans.

@@ElectronicsEditor & the way that fan was built is already inspiring me to do a window fan project just about the same way.

Yeah, the new bearings fit nicely on the shafts, but after assembled, they felt a little snug. It was difficult to get the two bearings lined up perfectly after the complete teardown (a slight misalignment while pressing them into their spots could cause this). Although, after running the fan for a period of time, they seemed to have worked their way into alignment much better, and I have been informed that now it runs and stops as normal. I figured they would settle into their spots better after a bit of use, so I wasn't worried too much about them.
