Lastly for today, I cut out the outside panel leading edge balsa blanks.
I used the heavier denser balsa.
12 x 100 x 1000mm 130.3 grams
12 x 76 x 1000mm 152.7 grams
I still don't have a building board to pin things to....particle board felt hard, and cork looked not quite flat. Maybe I'll use painters tape for now - not really a lot of balsa piece stabilization need, just a really true flat surface.
That's all for now...
