/diy/ - Do It Yourself

I have a Manning Bowman Number 31 from I'm guessing the late 50's that I enjoy using. I recently took it apart to replace the wire nuts used by the OEM to secure the wiring with insulated spade connectors. I'm sure some here would cringe at that but I figured it's better than the wire nuts.
Anyway, the reason for the post is I lubricate this fan with machine oil on the front and rear. There is a felt pad that rides against a brash bushing that holds the motor shaft. I've noticed that there is a hum coming from the fan and was worried if it was the sound of these brass bushings being shot. This is more noticeable when I throttle the fan down with a dimmer. The fan has no power switch or speed settings, just plug in and full speed. Linked webm is the fan with sound. webm related is the fan but without sound so pointless to the question.
