Hey Bob.

If I recall, you at least did the Hispano Suiza exhaust flanges out of that stuff.

What I usually use for thin stock is double sided sticky tape (not the padded kind), but the machining operation is a bit more complex than I would like. I am not certain that I could get the repeatability that I would like. I have had an offer (from one who shall remain nameless unless he chooses to reveal himself) to laser cut the styrene for me. I find that much more attractive. All I have to do is draw them up the way I want them to turn out.

The top end is a nightmare of horizontal, vertical, and diagonal fins. I don't think I would get satisfactory resolution out of balsa, and a mold may have to be 2 piece to even work.

ps. we'll try that picture again
