Sydney wanted to work on the plane so we got a short session in.
We removed the center section from the forward floor and took out the false spar hardware. Then we match drilled the 1/8 holes on the top of the center section and the nutplate rivet holes (#40). Then we machine countersunk the nutplate rivet holes . Then it was dissemble time for the centersection so I could deburr. And I primed the countersinks
Match drilling the forward and aft center section pieces.
