In this work session, I worked on fluting and beburing the F-706 and F-707 Fuselage frames. I was largely unsuccessful. And I also ended up drilling 8 uneeded holes in the F-707 frame, instead of the F-708 frame. Furthermore those holes were in the wrong places. It really didn't matter that much, but I was so annoyed by my missteps that I just reordered the F-707 frame and resolved to start all over. It wasn't cheap, and hopefully it will get shipped out soon. Finally I purchased three good aluminum saw horses, and laid out the F-778 Aft bottom skin in preparation to assembling the empennage.
