Focus Wing Tube

[ronlock]

It's my understanding that the tube spar MUST extend into
the wing a touch more than 10 inches.   10 inches is where 
the rib structure is to take flight loads.   Apparently some of 
the early production kits had a problem in that area that was
since corrected.

My kit was one of the very early ones.   I sharpened one end 
of the tube spar, seratted (?) it a bit, and used it as a hole
saw to cut through whatever was at the 9 inch point.   
Pesky but do-able.   Being a bit cautious, my  tube
extends into each wing 10 1/2 inches.  Maybe you 
want to call Piedmont to verify, they have been 
very helpful.

  Anybody got any ideas on how to get the wing tube spar into the wing on a focus. If I force it any more, it will break something. About 9 inches is all I can achieve.
