LDM, what thickness plywood did you use to re-inforce your ribs? I will be making new half ribs(from the spar forward to the leading edge) so that the new ribs will be the main box. Then after that, did you also make a rail (one per side of retract) to bolt or screw the retract to? What did you use for the new rail, Plywood or hardwood? What thickness was your rails?
I thank you!!
