Today was just prep work, getting the ribs and spar ready for attaching the skins. The first task was to countersink all of the holes in the spar...this is a large number. After about an hour's work, the holes were done and the compressor was about toast. I will be purchasing a compressorl soon. Following the countersinking, I deburred all of the ribs, then I used my pneumatic squeezer to dimple them. Not very exciting, but after I deburr and dimple the skins, the wing will come out of the stand and the fuselage kit will be inventoried...progress!
