Cut out and added the two nose rib doublers to rib station 13 to accomodate the centre leading edge plywood. The 1/16" ply was needed to pack out from the 1/16" gusset already glued to the existing nose ribs (refer to 2nd picture).
Also cut out some aileron cove triangular supports and attached them to the end aileron bay ribs. I am still thinking about the trailing edge in the aileron bay. Most people use the aluminium stock trailing edge and I do have some of this but I am also thinking about using shaped spruce between each rib end and using 1/16" ply on top and 1/32" ply, curved and glued for the cove. Still undecided.
