I spent a lot of time over the last two days finishing up the wing ribs. Cleaning and etching took most of Friday evening.

Etching the wing ribs

With all those ribs prepped, there was nothing left to do but prime them…so I did. John Sannizzaro kindly lent me the use of his paint booth, otherwise I’d be waiting for a really warm day to do them in the back yard. Even with John’s facilities, priming those ribs took a significant chunk of the day. Here they are in their yellow-primed glory…

Wing rib priming complete!

I’ll be putting support arms on the jig over the next few days, then it’s time to rivet the wing boxes together.
