     FWIW - The Bencher Skyhawk I installed last year required no such
prework prior to assembly.  The element tubing slipped together without
catching on burrs and the rivets dropped into their pre-drilled holes
without my having to redrill a one.  The boom-to-mast assembly is actually
two separate aluminum plates (a' la F12):  one plate bolts to the mast, the
other to the boom.  During installation on the tower, the boom plate slips
over bolts on the mast plate.  No three-handed u-bolt handling required.  I
just checked the assembly manual, but these plates aren't dimensioned.  From
what I recall, they were both substantial in thickness - possibly 3/16
minimum.

     I will admit that the Skyhawk hasn't really been stressed by severe
winds around these parts(D.C. area.)  But all the elements and the boom
tubing are double walled.  There's significant overlap between telescoping
tubing sections.  Seems pretty robust to me (the darned thing weighs 75
pounds!)
