My Unisaw has started making a funny noise a few weeks ago. I couldn't figure out what it was. I figured it would either quit or get worse. When it got worse I could find it.
Today I was changing the blade to a dado stack. With the blade off, I raised the shaft up to make it easier to reach when I noticed a spiral pattern in the dust on the elevating shaft. A quick look and I saw the noise maker. The pulley on the motor was rubbing on the shaft.
That meant I had to take the top off but the fix was simple enough. What I found was that set screw was missing in the pulley. Probably laying somewhere in the sawdust. I ran a HUGE old TV magnet in there but found nothing but the metal cabinet. Luckily I had a set screw in my parts. Put it back together, aligned it and no noise!
