RE-assembled R-HS skeleton and skin and match-drilled HS902-R

In order to complete the match-drilling of the replacement HS-902, it was necessary to assemble the full skeleton and match drill through each rib into the web of the spar. Then the skeleton had to be assembled in the skin so that the flanges of the spar could be match-drilled to the skin.

This was a simple process and went without significant problems. Of course the skin does not fit as well as on the old spar because it has been dimpled and the spar flanges have not yet been countersunk. Consequently, the skin sits on its dimples and does not yet lie flat against the spar. This knocks out the alignment of the remaining holes in the skin and main ribs so I decided that I would not cleco these for the match-drilling operation.
