I am getting ready to assemble the ribs to the spars of my S1C Pitts. The top wing is a swept wing. The ribs are built to plan. It seems to me that the openings where the spars go through have to have an angle sanded or routered or applied in some other way so that the ribscan be set parallel with the longitudinal axis of the airframe and not perpindicular to the spars. Any help or suggestions would be appreciated.
Thanks in advance
Matt
