Finished the aft ribs and started pre-drilling the center ribs for routing.
New band saw blade made for easy trimming of the excess aluminum. Although using a narrow blade is a stinker because it tends to wander. Perhaps some more tension is in order.

Got them in the router table, and life is good.

Had some more helpers in the shop tonight, doing a fine job with the drill press, as well as general supervision of events (guess which ones are the supervisors).

Have to be mindful, though. The .032" ribs have different aft lightening holes than the .025" ones. There's a separate jig/pattern for that hole. Don't screw up!
