RE: Westbury Hunter Build Thread
Working from the lower surface, troughs were cut out to take the 1” aluminum tubular spars. These were lined with 1/8th ply to form boxes, and then some cross-grain balsa was profiled to fit around the tubes to spread the spar loads into the wing skins. This balsa packing was also used to set the anhedral and incidence of the wings, needless to say this has been the most tedious part of the wing so far. Two Robart incidence gauges and some blue foam jigs have been used to ensure that the two wings are set up the same. I’ve just added the epoxy to glue the spars in place.
