CF minimum diameter build progress

So I've made some progress on the Viciously Mean Machine and unnamed 38mm spike below. I've applied Cotronics 4525 high-temperature epoxy fillets to all fin/body interfaces and laid up tip-to-tip carbon fiber reinforcement on all fin pairs with Aeropoxy. I've also post-cured both tubes in the oven for 1.5 hrs and, let me tell ya, those fins aren't budging even 1mm!!

This week I plan to build/reinforce the payload sections and couplers and start the finishing process. Both should be lookin' purdy by PB.
