So I've got the front and rear spars put together, and now it's time to drill in all the ribs in the correct locations. I'm curious if I should drill them in the locations per the plans, or should I pull out the skins and place them on the spars to see -exactly-where the ribs should so so that the skin and ribs will match exactly along the edges.
Many thanks!

The ribs are pre-punched as well. Grant, are you talking about drilling the flanges on the right and left center forward ribs?
I drilled these in assembly with the skins clecoed in place - this allows you to keep everything rigid and confirm that the placement is correct. I think that's how the manual says to do it.
You do drill the pilot holes as per the plans / measurements, but the final holes are drilled in assembly.

Grant.....Draw a line with a sharpie down the center of the rib flange that you can see through the holes in the skin. Its just a good check to make sure you are drilling in the center of the flange, depending on your fluting technique the rib may not be perfectly straight........Larry
