Brief Description: Riveted rear spar, leveled and squared right win i
|
|
Got a lot done today really. I located and drilled the tip rib to the rear spar. (with flush rivets) I riveted the rear spar to each rib. I still have to rivet the doublers for the aileron brackets, but I ran out of that length of rivets. I placed the right wing back into the jig, and squared it all up. It takes quite a while to do it right, but lengthwise, crosswise, spanwise, and diagonally, this wing is SQUARE. Next I took some allthread, and ran it through the tooling holes on the nose ribs. This will allow me to align the nose ribs to the main ribs. I finished by marking centerlines on all the nose rib flanges, and marking the line for the spar splice. I should be ready to fit the leading edge skin now!
