Using the "an hour a day" method, I've slowly progressed to the point where my firewall is finished! It looks very good, and it's solid too. Pretty cool. I debated about whether or not to prime the whole thing and ended up doing it. I figured it couldn't hurt, and I've primed all of the othe mating surfaces - might as well do these too. I still need to bolt on the top landing gear bearing, but it's been measured and cut to size - just ot bolted yet. Next time. Woo hoo! Another sub-assembly complete!
