Ed, How about the printed circuit board material? Its fiberglass and you can get it without any metal on it. It goes by many names, FR-4, G10, NP510A NP511 etc. depending on the manufacturer. Some manufactures will send you 18"x18" sample sheets of various thickness for evaluation. It is easily cut and drilled with a Dremel tool. I was condidering using it as aircraft skin material. One of our Delta Builders actually did use this material as skins. Jim

Might be less work than trying to develop a manual "pick and Place" gantry {:>). I wonder what is easy enough to cut but will withstand 468F for 90 seconds?
