I'd be in for one or two. Work has finally started on the WACO. All top wing ribs are cut, and center section has been started. I was going to cut all of the wing ribs for the bottom wing at the same time, but my hand was cramping up.also, my work bench was about a foot too short, so I had to build a bench on top of a bench if you will. One thing I do like about it, it brought my bench top from 36 inches up to 41 inches high. Much easier on the back.
