Brief Description: Prepared and Drilled Inboard Left HS Ribs, Final D
Marked all of the rivet hole locations on the inboard ribs so that I could flute and straighten them for match drilling. Had about a zillion clamps to hold the interface between the forward spar, skin and inboard ribs to make sure that everything lined up OK. Match drilled the holes from the inboard ribs through the forward spar and reinforcement angles. Turned out OK. They aren't as straight as I would like them. I used the right angle attachment on my Dremel tool and I could get perfectly perpendicular to the spar face because of an interference between the right angle attachment head and the rib. As is always the case, I had a bit of an epiphany after I drilled them. I have a flexible drive attachment that would have worked great. I'll use that on the right side HS.
Whew! That's a lot of Clamps for Drilling Four Holes.
