This divides the ribs into quarters. Do I predrill all the holes in the doubler to match the skin before match-drilling to the ribs? Am I missing something here? It is hard to match the skin and doubler to the ribs if you can't see the hole in the rib.

Then match drill to #40 with the top skin on.

I put mine on my workbench, placed the 902 skin over top, aligned it according to the instructions, and then drilled and clecoed directly into the wood. Once you've got these holes drilled it is easy to do the rest on the wing.

I did have the 3/32" drill ready ! The 902 and doubler fit beautifully. Next question: a nasty pucker on the forward edge of W903. I have the spar absolutely straight. Do I match-drill starting on the in-board end of the 903, working my way to the out-board end, with only the ribs holding the skin? Any suggestions, please. Cliff
