I am finally getting to assembling the wing structure. At a high level, this includes attaching the ribs to the spars and then skinning the entire wing.

I decided to start with the right wing – no particular reason. I laid the main spar on my work bench and drilled a “pattern” center spacer using the pilot holes on the spar web. I drilled all the spacers under the “pattern” in the drill press. I repeated this for the web spacer and clecoed the center and web spacers plus forward and aft ribs to the main spar.

This is after all the ribs were clecoed.

I took the help of my wife to place the assembly over a pair of saw horses so that I could updrill the rib attachment holes in the spar easily.


This is work for the next weekend.
