Before I give up on making my own, though, I found one other material I'd like to ask you about: from the same local source as the mica I found phenolic boards. These are (by eyeball, again) about 1.2cm x 10cm x 40cm and about twenty clams US. Thought I could cut several from one of these. Someone pointed out that mica would likely fail mechanically and also probably absorb water. Do any of you know how the phenolic would fare in this regard? Thank you, Eric
