I am having some problems establishing the datum line needed to weld my fuselage top and bottom sections. Question: are the tubes that make up the firewall on a PA-14 (or PA12, PA18) set 90 degrees to the upper longeron (from the door post to the firewall)? The plans are a bit sketchy here.
Thanks,
Marty
