Here’s the body tube with cardboard mock fins taped on, and the ring fin around that. Fin size looks pretty near perfect. Could stand to cut them a bit more generous I guess. I trimmed the plywood to size, having initially cut it about a half inch wide before gluing it on. One end isn’t quite stuck down so I forced some glue under it and put it back under the clamp. I’ll want to treat the ring edges with glue and that’ll be it.
I realized I needed one more piece of 1/16″ x 4″ balsa, and I could run out to the hobby store I was just at yesterday or the nearer Michael’s, or I could do it another time. I’m doing it another time.
