"Making Composite Fins for low, mid, and High Power rockets"
by Rick Vatsaas
For the evening's topic, Rick presented some ideas and
methods for making composite fins. He talked about
fiberglass, epoxy, molds, and vacuum bagging of small fins.
Rick shared some ideas for doing vacuum bagging inexpensively.
He uses "ziploc" type bags that can be evacuated using a small
electric or manual vacuum pump. Instead of peel-ply, he
uses ripstop nylon. Rick demonstrated by mixing up some
epoxy and vacuum-bagging a balsa fin right on the spot.
