Made a pattern from a 1x3.5" pine borad to get fit for firewall top aft cross member. Cut final from spruce. Because the fuselage had been widened, the stock wood kit ordered from Wicks was not long enough to make all the fuselage firewall cross members. Ordered a 4 ft board from Wicks to make the top aft firewall cross members. Epoxied the top aft firewall cross member in place.
