More Spar Countersinking

Just as the title says, I spent my time in the shop today countersinking the remaining holes in left wing spar for the wing skins. The left spar is all done (countersinking), and ready for the skins.

Yup, those are countersunk holes. Not much I can say about them. I used my cordless drill again and I am pretty much convinced I like using the cordless better than the air drill for countersinking. But hey, that's just me.

After I was done countersinking, I masked off the spars and sprayed a light coat of the SEM primer along the spar caps. I figured that since the skins meet here, it would be good to put a little primer here.
