--> RV9-List message posted by: "D, C, Jones" <cliffjones@look.ca>
Van's instructions say to position the W927 under the 902 skin, then to drill the
8th, 15th and 22nd fhole rom the forward edge. 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.

You are correct drill through the skin. It's much easier thay way.

Cliff,
I driled all of the holes out using a 3/32" bit, which is the size of the
pre-punched holes. Then match drill to #40 with the top skin on.
Matthew Brandes,

Cliff,
You need to match-drill these initial holes in the wing walk doubler
off wing. 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.

Thanks to all for the quick responses on the wing walk doubler question. 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.
