Sorry Don, et al,
Please forgive the brief digression before returning to the subject.
OPEC started its antics in the summer of 1973 - remember it well, my uncle
lost $100K US in the market panic that followed. I avoided boats built after
the late spring of 1973 - A-30 KC 544 Windrose was built in June, '73 which
I bought.
The oil shocks were felt for about 5 - 7 years after and resulted in the
1975 recession. If you remember the Trudeau governments projection that oil
would rise to a sustained $50-70 a barrel, which would wipe out the Federal
deficit by 1980, with oil revenue, you will then remember how lousy
forecasts like that are - taken in isolation as to the macro effects high
oil would have. Stagflation resulted and lasted for the rest of the 70's.
Labour costs skyrocketed. The Canadian deficit didn't get under control
until Chrétien / Martin got to the helm 20 years later.
But I digress, back to the subject:
I agree with you that people not keeping caulking up is the primary cause of
deck rot - I rebedded everything, particularly stanchion, working jib
tracks, chain plates, rudder head, and stem fitting. On the bigger holes
like the rudder post and chain plates, I routed the coring with a dremmel
the radius of the bit and filled the edges smooth with Marine Tex before
rebedding.
On the bolt holes I taped the bottoms of the holes and injected epoxy in and
then redrilled and caulked to give the coring half a chance at a seal.
The most important thing is to not seal with caulk the underside of a bolt
hole, so if the top seal fails you will see water ingress coming through and
dripping, which tells you its time to rebed that fitting. The coring seems
to be placed chock a block with voids between the balsa - must make for
great rivers if the water seal fails.
Finally, the one thing good about economic forecasts though is the farther
out they are in time, the more inaccurate they will be - one thing forsure,
the numbers called for can be relied on being the numbers we won't see ; )
Many thanks.
Cheers,
John
