The next step was to reinforce the fins with self-adhesive reinforcement material. I peeled off the backing and stuck each piece to the sticky side, then I carefully trimmed them with a hobby knife. The process is repeated for the other side. After that, I used a kitchen spoon to burnish the material onto the fins.
I applied some CA to all of the exposed balsa edges (except the root egdes) and sanded them smooth.
I have only used this process once or twice before on other rockets, but it really makes strong laminated fins with no need to fill any of the balsa grain with sanding sealer or wood filler....
