First job today was to mark the locations of the two strut attach bolts between ribs 7 and 8. Two 3/4" holes were then drilled to take the bushing material which itself will be drilled for the 3/8" bolts that fasten the strut attach brackets to the main spar.
The bushing was then glued into place together with the rear 1/4" thick 12 ply plate. The 3/8" holes will then be drilled through the centre of the bushes and the rear ply plate. Then the front ply plate can be installed and finally the bolt holes drilled through it as well.Then it was a case of gluing and pinning the corner blocks that strengthen the joints between the spars and the ribs, easy enough but took most of a day to complete - this must be the equivalent of dimpling when building in aluminium. This completes most of the wing structure, remaining jobs are to install the leading edge between the root rib and rib #2 and four blocks along the aileron spar to take the aileron and flap attach bolts. Then it's time to sand everything ready for the lower wing skin. The wing tip will not be constructed until after the lower skin is glued into place. I still haven't decided whether to do an all wooden wingtip or the original Wittman design which uses metal tubing to create the aerofoil shape.
