I used layers of 9 ounce RA7725 (as Aircraft Spruce calls it) fiberglass to make my last spinner, and it's just about perfect. It weighs something like 4 ounces, as I recall. Using 5.85 ounce 7533 (KR cloth), two layers wouldn't be enough...four would be required for similar properties, and that's four times the work and opportunity for wrinkles. It should work though. Give it a try. I tried to send this from OSH but something changed with my SMTP port number and I couldn't send from my iPhone. Mark Langford ML at N56ML.com http://www.n56ml.com
