Attaching the firewall turned out to be time consuming. I had to adjust the length of the longerons many time, fit the longerons and re-do. I guess I was pretty conservative in my adjustment of the longerons length, so it took many iterations. After being happy with the fit, I started drilling the fire wall, that took some time and many drill bits, since this is drilling through steel.
