I think Peter uses either Rubbermaid or Tupperware for water resistant his variable capacitor. Or, you might try an inverted Glad sandwich bag draped over the wood block and Vari/cap to protect from water.   LOL :)

Yep, we know about the HV issues. The cap is run by a NEMA 17 stepper which Al has geared down. The stepper controller goes to 1/32. We're still experimenting with timer interrupts to slow it even more, and then speed it up. More work.
