Drilled and reramed wing mounting holes on center section. . Shown is left wing, right wing done first. Uprights were installed on fwd edge for the drilling and reaming. Bolts required a .3105 reamer. Rig pins were also good with the .3105 hole. Snug but bolts do slide in without too much trouble. Also gives a good idea on how much the wing skin will have to be trimmed.
