Ripped up some 9mm MDF into 5 x 22" x 18.5" jig blanks, slightly bigger than plans to allow for a larger Turtleback. Couldn't find my pattern wheel, so just drew over the line with a marker, and enough got through to draw a cutline.
Trimmed flox blobs, trimmed upper longerons and removed clampy bits. I don't think the reinforcing layups will be achievable after the TB is in place, so decide to start them now. Applied Layup #1.
