Weather was not suitable for students today so I didn't go skydiving. Jackie and I made some good progress on deburring and dimpling. Jackie did some of the smaller components (access panels, leading edge light bits, etc) and made a start on the leading edge ribs. Then together we nailed the wing skeleton: it is completely drilled, deburred & dimpled. The main and rear spar dimples & countersinks require a shot of primer next time I have some mixed (Friday?), but they are otherwise ready for rivetting. Good job.
