Today, I got on with working on the firewall and associated parts. I clecoed the strengtheners to the cabin side of the firewall and drilled all # 40, #30, and the 1/4 inch holes through the backing plates for the flight adjustable rudder perdals. I used lots of Beolube to lubricate the drill to stop the stainless steel blunting the drill. I also drilled the #40 holes in the middle cross piece and the right upright to get ready for the platenuts which will be riveted to them.
I then disassembled the parts and bent the top of the firewall to the required 8 degrees. Tomorrow I will start deburing, edging etc. I waited until now so that I'd do all parts at the same time.
After drilling some of the holes thourgh, the clecos are currently on the other side of the firewall.
