Default Re: Buffer Vibrates with new wheels

I used the center of a toilet paper roll as a bushing of sorts. (I cut it longways and than trimmed it so it matched the ID perfectly.) On the spiral side the fit is now very tight. The loose sewn side is way better, but not as snug as the other side. I might wrap some tape around the OD of the roll. Anyaway after a rerake, I can get the machine to 3450 RPM, but it still vibrates. Just a vibration, not the violent shaking that happened before. I am going to keep playing with the bushing diameter and raking and I think it will be OK. A little disappointed that this was necessary, but hey I am back in buisness.

The VFD is controlling a 3 phase motor. It varies the voltage and frequency so that the speed varies. The one I am using takes 220V single phase as the input and puts out 220V 3 phase variable frequency. It works great, and you can slow the motor way down. The only regret I have is that I mounted it to the buffer itself and when the buffer started shaking violently I was worried it would kill the $400 VFD....
