[Alberg30] A30 mast support beam

[Furey, Bill (CORP)]

George: couple of dumb(or maybe not) questions- 1. Can you jack the beam
up(carefully)
with the mast in place-if so-some tips,pls.
2. Assuming one uses the Washington Inc aluminum plates(they have them for
my boat,
A-35($285 a pair)- when you jack up the beam & fasten on the plates, to the
beam-
why won't the beam sag again(this from a non-engineer with a slight dislexic
problem-
maybe they're one & the same)I understand you glass or seal the extremities
& the overhead,
but is this enough??-thks.

Dan,

Jan Grodzinski posted (on the member list) a company that digitized
and cut the plates for him.  I've copied the company address to
