Brief Description: Deburring and countersinking left spar
Deburred all the pieces that got drilled setting W11-08. Then started countersinking the upper spar cap for flush rivets. Got all but 5 done.
The right spar has a few questionable flush rivets that may be because the countersinks were not quite deep enough. So I'm being extra careful on the left spar to go deep enough. Once you set the first rivet there is NO going back to countersink anything deeper.
