I have a better, less touch-feely idea for the pole piece damping. A board across the pole piece.
Maybe a 1x1 with holes drilled into it at the appropriate places NOT to fall into the vent holes.
THREAD the inside of the holes using threaded inserts. Use small dowel rods capped with FELT to the pole piece. Adjust tension with BALL POINT PEN SPRINGS. It doesnt take MUCH.
Once set, a DROP of locktite PER will keep the adjustment from backing out.
I'm working on a drawing. Using a phi-interval will prevent creating harmonics and creating additional problems. For example, a damper in the center of the PP will create 2 pieces with will resonate together at 2x the original frequency.
No fragile string for the CAT to get at. No, or LESS subjectivity to the adjustment.
Just a thought:
Too much is never enough
