Fin Cans
These are the "Fin Can Kits" I sent out. There
were 6 total kits. The materials were donated by Jerry Irvine. Each kit
had two birch ply centering rings, two 1/8 " plywood fins with a
3" root edge, a 4" long 29mm engine tube and a 4.5" long,
2.6 Dia glassine body tube. The instructions were to assemble the can
using a provided diagram. The construction
consisted of through the wall fin mounting and internal fillets. Three
were done with wood glue and 3 with epoxy. Each person building a fin
can voted on how to test them.
All parts were donated by US Rockets and Jerry Irvine.
