David asked:

Ditto the boom-stays on a Cuscraft 40-2CD; can I substitute a single
piece of 2" OD/0.125" wall 6061-T6 with a center sleeve of 10 ft of 2.125"


I bought N2TK's 40-2CD some years ago.  It had 2", .250 wall 6061-t6 boom.
No center reinforcement.  Worked fine.  When the hurricane caused the oak to
take out a guyset, it rode down from 90'.  The boom was the only straight
left.  Don't think I'd worry about reinforcing the center.  But it was a
22' piece.

I bought a 24' tube from Bethlehem Aluminum (Allentown PA) recently for
$125, for what it's worth.
