The ribs that attach where the doubler is installed have to be shortened so that they will fit. I have removed the flange on the rib to the left (with my handy dandy dremel tool...another thing I've been wanting for years). I have cut a new flange which is clecoed to the doubler. This will ultimately be rivetted to both the doubler and the rib. Once this is completed, I have to take it all apart and deburr the holes that I drilled where all the clecos were. Oh yeh...I also have to wait for those two missing ribs. Then it will be on to pre-fitting the skins...which looks like it will be quite a challenge to fit them perfectly so everything is absolutely straight. The trailing edge of the horizontal stabilizer is the attach point for the elevator. If I don't build it straight, the elevator won't be able to move freely...and de airplane no go uppidy and downidy ploper!
