Rear Spar Stiffeners

Satisfied by our completion of the Van's toolbox that we were indeed equal to the task of building an airworthy airplane, we dove into the empennage kit assembly.
First challenge: finding the rear spar stiffeners. Some trickster at Van's had placed them under a layer of cardboard beneath the skins...and I'd forgotten they were there in the time since inventorying the box.
We proceeded to break the edges of the stiffeners with a vixen file, radius the ends & polish them on the scotch-brite wheel to a brushed finish.
 Trying to save some $ I had ordered a Scotch-Brite wheel on Amazon...that turned out to be 6x1/4x1/2. Oops.
 We clecoed the spar stiffeners to the rear spar, match-drilled and deburred the assembly.
I'll be ordering a 6x1x1/2 Scotch-Brite wheel from one of the usual suspects, as no local auto or hardware store carries them. Lesson learned!

Empennage: 5hrs
