The centre cabane has 3 ribs that make up the basic surround. The outer two ribs are fitted and bolted to the frame using ply doubles to ensure that the bolt head can sit as flush a possible and so not impede the wing fitting.
Once these are fitted the capping beech can be added – tricky as it is quite a bend on the upper section so a combination of clamps and twisted wire keeps it in place whilst the Aerolite goes off.
The trailing edge is shaped ready for the balsa filling to be epoxied into position and then sanded to profile.
The stringers are fitted top and bottom and then the top leading edge sheet ply. Gussets are finally added before smoothing the whole thing down.
