First off, I have to say that this will probably go down as expensive mistake #1, since it’s probably going to involve a new HS710, HS714, and 2 HS702’s. I might be able to save them, but only if the skins fit.
So if you look at where the end of the ruler is,
the distance from the center of that hole to the edge of HS710 might not actually be 1/4 inch. it’s close, damn close, like just outside of 1.5D.
The other thing is, yours truly has committed the sin of building out of sequence. You’re supposed to take all this stuff apart and work with one side of the spars, and fit HS405 and HS708 (inboard main and nose ribs) with the skin clecoed on to the outboard ribs and HS702/HS 603. I did not do this. So what I hope now is that when I actually strip this thing and cleco it up correctly, the places where I’ve put the ribs (based on the 5-3/16 dimension in the plans) will allow me to matchdrill the skin to the ribs with no trouble. If not, well, I order some new parts and shave a lot less metal off this time. What happened was, I drilled the inboard main rib to HS702 before test-fitting the skin to make sure I had enough edge distance on the angle splices and the rib flange. But now if I don’t have enough edge distance on the inboard edge of the skin, I’m screwed. All I know is I’m not drilling anything else until I complete the skin-fit.
