The fin core layup templates. Tape it to the cloth and then I simply cut them out with 'special,' sissors.
CF cut. G11 surface prepped. LE/TE taped. BONDING.
Laying down cloth while wetting it out with 4461.
Just throw it in the bag. Pulled a good vacuum.
Close up on the bag under vacuum.
Straight outta the bag. Need to sand the root - a little over lap.
Sandy.
All done. Came out pretty nice.
Moving on to the FWCF can. Cutting it down to spec on my horizontal bandsaw.
Heres the fin alignment jig - all assembled. Credit goes to USC's RPL for the design.
Fins slide in and then so does the can. Fins can slide up and down in their respected slots.
Applied 4525 and slide fins down onto the tube. Let em cure.
Ass shot.
Fins tacked on. Starting to look like a rocket's fincan.
All measured, taped up, and ready for fillets. Laying down fillets with 4525.
Fillets done. Came out nice - will sand them smooth. 4525 is a slight nuisance to sand.
Moving on to T2T and ablative next next.
