k.. so I want to build a former... I like Doug Walsh's I like drcrash's very informative posts, along with his Instructable" and the tk560 site..
My mat'l of choice is gonna be lexan, due to availability. (Sure - I have to have the most PITA poly there is, huh?)
All I know is what I've read on 'net: Stays hotter longer, and requires drying (?) of 250°F fer dAYS.. - even then, it'll absorb moisture within seconds.
So, If I'm gonna build one, I have to use lex for formable mat'l.
anything else I should look out for?
