May 31, 2008 ...  I spent the bulk of my wing time pre-drilling the left wing upper skin. I fabricated two padded wing cradles that will allow me to set a Clecoed wing on my benchtop. This came in handy as it allowed me to lay the wing flat while pre-drilling the row of holes over the main spar caps.

 

I was miserably short on Clecos, but Bryon Stewart, a local aviator and  RV7 builder generously loaned me several hundred of his. Thanks Bryon!

June 2, 2008 ...  Today was a very productive day in the airplane shop!         I set the wing airframe back on the workstands and leveled (plumbed) it up again. I attached the left wing lower skin to the airframe and pre-drilled the rear spar, then working from the center rib (#7) outward, I pre-drilled and Clecoed  all of the ribs.

 

After that,  I was ready for a break from all the drilling so I cut and shaped the right aileron counter-weight. I finished out my day, enlarging the inspection cover hole, on the bottom wing skin, to 5 inches. I am going to rivet in a re-inforcing ring with nutplates, so that I can install the inspection cover flush with the wing skin.

June 3, 2008 ...  I only got a couple hours of wing time today, so I pre-drilled and Clecoed the lower wing skin to the main spar cap. But that completes all of the left wing skin pre-drilling. With both skins Clecoed, the wing is now very rigid!
