Now, back to the comment regarding rib W1. When Iadded the wing joiner, I found out that rib W1 required to be aligned with the centre line which is conforming to the dihedral. Some cursing and slow work with the knife, and many minutes later, I have opened the glue and was ready to glue the wing joiner and rib W1.
Ithen glued W5B false rib which serves to contain the huge wheel beyond former W5. To align it Iused a bit of 3/8" x 3"16" where the forward spar will go.
