I’m certainly no Freedom expert, but I have a fari amount experience with boat
repairs.
I would not use auto body filler for that purpose. First of all, it has very
little strength. Secondly, it absorbs moisture. Thirdly, it’s not a very good
adhesive, especially on epoxy surfaces like the mast.
If I were gonna add a filler to the bottom, I’d rough it up with 60-grade paper
then use an epoxy like Marine-Tex. Or mix epoxy with silica or chopped
fiberglass or carbon powder to a paste-like consitency. Those would be
viritually waterproof and a lot stronger. Better adhesion, too.

Nhat,
Perhaps you can fix it yourself by lifting the mast 1’ or so and use
a beltsander to even out the mast base. It will never be perfectly
square, but if you put 2 component polyester automotive filler
inside the mast collar on the floor and sit the mast down on the
soft filler, the filler will harden underneath the spots that don’t
touch the base. That will do, I think. And of course make sure the
mast base is totally locked and doesnt move around inside the
collar. Use polyester filler to do that and put the bolts back in.good luck,

First off I greatly appreciate all your input. I found Lance’s
reply
most accurately describes my situation.I do have one crew and was able to take a look at the mast base.
Under stressful conditions, even at anchor, when we’re rocking
from
side to side the mast moves slightly and rubs against the bottom.
It
basically scoots to one side and creates a loud vibrant clank.I do believe, as Lance pointed out, the starboard side of my mast
base appears to be harder pressed against the floor and is not
square. My question is then will lazer cutting that starboard
side
help? does it mean that the mast is really just sitting on the
thru
bolt instead of the floor? How does one get a lazer cut done,
especially in Puerto Vallarta of all places anyway :)?Any ideas for an easy temporary fix that will carry me to the end
of
my journey back to the States where I can get it fix? Or maybe
just
living with the noise? Any opinions?My first thought is now to just tighten the thru bolt even harder,
but I fear overtightening it and possibly tearing up the screw
threads.My last and final choice is just to sit back and enjoy the sun and
some beer and pray to the wind and water gods… I suppose?Thanks and please advise,

on Glory, the PO had creaking and noises from the mast as well.
During
a refit at Paul Dennis’s yard, Paul found that the bottom of the
mast
was not quite square, which was causing the mast to shift
slightly.
They made a laser cut to square up the bottom and the noise went
away.Also, I would use caution if you decide to use wood wedges -
they
were
never recommended by Freedom or TPI. If you do go that route
because of
a lack of other materials, use many wedges so that you can
distribute
the compression loads, otherwise you risk crushing the mast
tube.
Your
best bet is to search the archives here and on the 2003 group
for
references to either pourable polyurethane or cutting wedges
from
polyurethane block - 76 durometer if memory serves.Good luck!
