I'm making some large balsa fins about 12 inches long with a 6 inch span and a basic trapezoidal shape. They are going to go on a 4-foot rocket powered by a D engine. My 6 inch wide balsa stock dictates that the grain runs parallel to the body tube, which of course is not ideal. So I have three ideas and I wonder which is best?
A) 1/8 inch stock, grain parallel to body tube (no balsa waste). Paper for strength.
B) Buy some extra 1/8 inch stock rotate it so the grain is parallel with the leading edge and edge butt several pieces together to get my desired width and cut my fins from that (produces balsa waste). Paper for strength.
C) Laminate two 1/16 inch pieces together at 90 degrees and then don't worry about the grain direction (no balsa waste). Paper for strength.
D) Other
Thanks!
