Had to cut and plane some more cap strip and stiffener material. It's amazing how quickly 10' of wood can be used up on a few ribs. While I was at it, I cut and planed some poplar as filler in various places. For example, it will be used in the gap between the ribs, between the spar and the skins.
Glued the cap strips and stiffeners to some of the ribs.
Steamed and bent cap strips for the remaining rib sections.
