With the lower skins for the left wing completed, it was now time to do the same for the right wing. I started by scuffing the contact areas on the inside of the skins. Then I used the circular sanding disk portion of my bench grinder to thin the material on the overlapping leading-edge corner of the two skins. I also used the edge rolling tool to put a slight bend in the leading edges of both skins. The DRDT2 dimpler was then used to dimple all of the flush rivet holes in both parts, A quick cleaning with acetone and I then some self-etching primer was applied to the skins.
I had a little more time while the primer was drying, so I used the countersinking tool to recess the skin-facing holes in the pitot tube mount. The three holes that mount the pitot tube to the spar flange don't need to be recessed because they match against the flat portion of the spar.
