Priming and assembling front spar

4.0 hours

I dimpled the right hs skin. This time I created no extra holes with the dimpler. I cleaned the parts with soap and water with a scotch-brite pad, then primed them with SEM. It took the whole can as it was somewhat windy. I didn't have enough to do the skins, and only had 1 can.

I started riveting together the front hs spar. I used the avery hand squeezer. It makes perfect shop heads once it's set up. After about 30 rivets it got a little harder to squeeze the rivets, but it was tolerable. My countersinks for the flush rivets turned out to be too shallow. I guess because of the primer. So I have to drill out my first rivets, as 4 of them don't sit quite flush.
