Fins and Tubes
Cut the fin templates from paper, transferred it to cardboard, then to some 1/4" plywood which was cut using a scroll saw and then sanded to shape.
I also prepped the tubes for the fins. The Lower Fins will glue to the internal C-60, the Upper Fins and Launch Lug Mount to the surface of the BT-60.
Using the OpenRocket fin guide the Body was layed out for the fins. Using a circle template, 5/16" dia. circle were drawn on each of the Lower Fin locations, and a 1/4" dia. circle for the Upper Fins. Lines were then drawn for the fins from the outer extremities of the circles. It's just an easy way to lay out the tube.
I used my 3/4" aluminum angle as a straight edge and then cut the slots into the tube.
Elmer's School glue was used to attach the inner C-60 to the Outer BT-60.
