Ive used a piece of fiber glass copper clad board used to make PCBs. I
spin it up to 10,000 RPM with two small electrodes mounted. No
vibration. The copper clad board costs 2.50 (GBP) from electronics
supplies.
I managed to balance the rotor by mounting the rough cut piece on the
motor shaft, spinning at low revs and using a spinning grinding wheel to
shape the disk. A grinding wheel is the only thing I could find that
can cut fiber glass when its on the move.
The copper at the center of the disk has been etched away.
