[Elecraft] I got big heavy knobs...

[Slava Baytalskiy]

Thats exactly how i did it. I'm actually using both felt washers on the VFO A and one on VFO B.
I have the regular (all black) knob set from 73cnc.com (couldn't wait till Dayton to get the deluxe).
But they are great.
Did you know these guys picked up the K8RA's keys business?
I just got my P4 iambic from them on Saturday at Dayton.

That means that there is no contact with the felt washer, and the weight of the knob is like a heavy lever placed on the end of the encoder shaft which would have a tendency to bend the shaft.
