Hi Kevin,
Feel free to post your build here. It always helps to bounce ideas back and forth.
I just finished the drilling and tapping of the wing joiner blocks. The tap I borrowed was a 4-40 3 flute tap. Wouldn't you know it on the 3rd hole it snapped with very little pressure

. I was stopping and turning back every 1/4 turn to clear the chips and it still snapped on me. As always happens 5 minutes later I found my missing tap. It is a 2 flute tap which is much stronger and I was able to finish tapping the holes.
After a short break I will get the plans for the wing down on the table and I will start framing up the 1st half.
Later!!
Anthony
