Wow, you guys had more fun, I just did some repair work. Nice job!
I finally got around to diagnosing the vibration and noise in the head on my mill. I thought it might have been a bearing in the motor or intermediate shaft, but as it turns out, it was just a worn bushing in one of the sheaves on the variable speed pulley, which made the pulley wobble. Luckily I caught it early and there was no damage to the sheave itself or the motor shaft. I ran out of time today, but I'll make a couple new bushings tomorrow, press them in and she should be good for another 30 years.
At least I got to try out my new bench.
