it is easier to simply replace their bracing system with a pair of
turnbuckles a few u-bolts, a small metal plate and some cable....
This will give you infinite variability in your trussing options. When
assembling the beam install the boom-end ends of the trusses (go Philly if
you are a purist) and attach the turnbuckles to the top ends then tape each
half of the truss to the boom with masking tape....once you have attached
the boom to mast plate then do a preliminary positioning of the plate which
the two turnbuckles will attach to, lightly tighten the u-bolts.......tear
the guys free from the masking tape on the boom and bring their turnbuckles
to the small plate with the u-bolts....attach them...loosen the u-bolts and
push up on the plate until the slack is taken out of the trussing guys.
Then tighten the u-bolts, and tighten the turnbuckles til the boom is
level......oh yes, bring something up with you to pass through the
turnbuckles so they don't unwind, a piece of heavy gauge solid copper house
wire should do.
Like front wheel drive cars drive better than rear wheel drive cars do
(they pull the car rather than push it)....trusses which are from above
seem inherently more structurally feasible....MHO as a Mech Eng drop out!
