Brief Description: Longeron - Drill 721 canopy Deck to Longeron.
Starting at the forward end I clamped and drilled. The first 10" or so has no curve so it's easy to alaign flush and start drilling. Then move the clamps down 10" or so, checked for flushness and drilled some more.
The end result was a very nice fit. I'm very happy with it. My eye and finger nail detects near perfect flushness. Oh good.
