Right wing ribs primed, Left wing match-drilled

It was great to be home for the first weekend in a while! I continued deburring wing ribs, and tackled drilling conduit & wire runs for the tips. First a sophisticated template to mark the drilling location with a spring-loaded punch,

 Then drill to #40

 Followed by #30 

 And then upsized with stepdrills

 To final dimension of 3/4" (below) and 5/8" for the tooling hole near the rib root.

 My buddy Chris came over and got all the glamorous work: washing, drying, & priming ribs.

 Ready to go!

 Not bad for a squiddie.

 While the primer dried we match-drilled the left wing main ribs.

 Rear spar first,

 Followed by the main spar.

 While that was happening I drilled the tooling hole in the main spar for the stall warning device up to 3/8".

 Deburred, bushing installed. Too easy.

 Prime(d) rib!

 Chris's boy Naish heard there were power tools and had to get in on the action.

 We also got the leading edge ribs match-drilled & deburred, the main spar hole deburred, and Chris knocked out all the hole deburring on the main ribs. This stuff goes much faster with help!

We had an awesome day, got a lot done, and are ready to rivet the skeleton of the wing. Almost time to skin that beast! Can't wait to have Chris & family over again to help.
