I really admire the research you have done on this and I do look forward to seeing the project when it is completed.

Thanks for that submission Charlie.
I wonder how that Durobond stands up if molded in a very thin form,...say 1/8" or even 1/16" ? I think the other model molding materials will be to brittle at this thickness without some sort of wire screening, etc as reinforcement.
