Here's the score - or - Into the scrap pile...

The score is CX4 1 - Greg 0

I was doing okay starting the riveting of the center spar.  Then - the novice (me) messed up.  The rivet gun got away from me.  And I total destroyed the spar web piece (.040 sheet)

See the total destruction in the pic below:

So it's in the trash it goes (actually I'll save the pieces for scrap - but D***MN I'm mad at myself!  This is probably the first of what may be other screw-ups.  But I am not a happy camper...

I'll try to learn from this and move forward.

Grrrrrr!

Thanks for listening....

Greg.
