The parts were acquired through internet purchases, friends and stuff I already had from other projects. The 4 inch fiberglass tubing and matching coupler where purchased from Alan over at Hawk Mountain. I already had the nose cone that was for my Black Brant II project, but it was not to scale so I need another one for that rocket anyway. The 4-inch .125 wall aluminum tubing and 4-inch aluminum round rod came from OnLine Metals.com. The G10 for the fins and the alt bay boards came from Bill Begg's and the remaining hardware came from McMster Carr. I had the fiberglass cloth for the fin can glass other miscellaneous hardware. Now on the the fun part of actually building it.
