RE: SIG Fourstar 40 (4*) Build Thread
Before gluing in the shear webs I braced the outer rib to keep it straight and prevent it from bowing outwards.
I dry fitted the shear webs and sanded as needed. I then dry fitted the top main spar to make sure it would seat flush into the slots, then glued them all together. The top and bottom TE sheeting and spar are also shown glued in place.
