Brief Description: Front seat support bar; firewall straightening
Riveted the left half of the front seat attach bar to the fuselage.
The 2x4 that I clamped to the firewall last weekend did help straighten the firewall a bit (from 22 down to 19 degrees), but it clearly was never going to achieve the required 8 degrees I need. After fiddling with various ideas to overbend it backwards a bit, I simply removed the 2x4 and bent the top of the firewall by hand. It worked fine -- I got the required 8-degree bend pretty easily.
Clecoced the top skin on the fuselage and confirmed that the forward edge of the baggage door opening was not being pulled by the firewall anymore.
