Here is the finished firewall. I left the carbon plate covering the stringer slots, this makes for a cleaner look. Shaping the carbon is easy with 150 grit paper on a block. At 65 grams this works just fine.... next step is to mark and drill holes for the blind nuts. I lost .2 gram after trimming the carbon from the firewall, using 200 lbs in the press helps put the squeeze on.
