Myers, thanks for the link. Sounds like it's a fairly wide-open list of materials that fall unter the "Micarta" name. I've probably cut the stuff, at work. Reminds me of G-10 fibreglass,, which I tried to use as an insulator in my first Stirling. It didn't hold up to THAT much direct heat. ;D
J.Tranter, the material I used was a pressed-Mica board, I have some pieces left over from foundry parts we made from it at work. It splits very easily along the grain, just like raw Mica. It's also very abrasive, even to carbide tooling, with nasty dust. I decided that if anything that bad, and expensive, was being used in a foundry, there must be a good (insulative) reason for it, and that the small cut-off bits were worth saving for the boiler saddles on my Crackers.
Edit, apparently, acording to the manufacturer, and the MSDS, the dust is non-toxic, and "only" an irritant. Still, I wasn't hanging over it while machining it, and I used coolant to keep down the dust, like I do with all of the graphite I work with.
