Aux Longerons; Stiffeners; Drilling
Today I got only a moderate amount done on the airplane because I went and did my flight review with my old instructor that taught me to fly. He doesn't instruct full-time anymore (he flies Beechjets instead) but he keeps his CFII current and came out as a favor anyway.
Anyway....after the flying a bunch of folks from the airport went over to a local pizza place...I eventually made it home and started cranking again on the project. The picture above shows basically all the work I got done. Note that I drilled the outboard seat-ribs to the forward skins (I don't have pictures of that below).
I drilled the aux longerons and the forward skin stiffeners on both sides. This got kind of interesting and I had to get Jaime's help to do it...since there's absolutely no way to clamp them that I could figure out. Jaime pressed outboard against the skins with a wood block while I drilled from the outside.
The stiffeners are sort of odd...they get attached to the firewall with the funky bracket that has to get fab'd.
And here's how they get attached....now...the question is how in the world are you supposed match-drill this thing to the skin???? You got me...I decided to go ahead and do other things after I couldn't figure it out. I'll look around the regular sources to see how they do it. I may just end up making new brackets and not pre-drilled the hole that attaches to the firewall...then I just eyeball the hole and drill it from the inside out.
I went on to other things...including drilling the two fuse halfs together. I hadn't done it...so I figured now was a good time.
