More rocket building! She is almost ready to fly. I skipped a step involving putting glue into a spot I firmly believe there is no way to get to without some specialized tool (super narrow and long glue syringe?), which I don’t have. The glue was to firmly connect the fins to the body tube, so I figured I’d just make some mega epoxy filets on the outside. Same thing, right? Actually no, because epoxy is way heavier then CA glue, so she’ll need a CP/CG check once everything else is done. Basically: if the center of gravity (CG) is too far aft (i.e., behind this rockety thing called the “center of pressure,” or CP) the rocket naturally goes into a turn–not a spin, a turn–as soon as it’s in flight. Turning rockets are bad juju. Speak of bad juju, I will add–at risk of jinxing this whole thing–that I am a wee bit worried that the fin mount rings aren’t well-enough secured to the motor tube. If that concern bears fruit (weird way to say it? yup), then the motor and motor tube will blast through the rocket and fly god-knows-where, spinning and turning and corkscrewing at speeds extraordinarily unbecoming for such behavior. Exciting! I believe I will wear scientist goggles and hide behind a piece of plywood for the launch.
