Lots of drilling, lots of countersinking, and then more drilling, and more countersinking. Yep that's the entire section to prep the spars.
I alodined the thick parts and the bare aluminum since I'm not planning on priming any of wing parts, but we'll see.
I've already moved on to the next section of the plans and am excited to get the ribs attached. That part will be rewarding.
I worked on more stuff for the baby's room (she'll be here next week, wow!), so today I have about:
6 5.5 drilled and countersunk, nutplates
7 5.0 alodined parts, made tiedowns, riveted
