G'day,
You will not save much by bagging the small panels individually. This
is what blew the budget on Sol 1. It is quicker to nest them on a big
sheet and cut them out afterwards.
Wet laminating and bagging both sides in one hit is much quicker than
setting up for infusion. Sealing the bag is time consuming, but good
preparation and practice speeds it up, as does good tacky tape and a
hole free bag.
Tape down one long edge of the bag before you start wetting out, apply
the tacky tape to the other edges and roll the bag and cover it to
keep it out of harm's way. Run a piece of tape over the area to be
sealed to so that resin cannot get onto it. Put the cloth on the
table and have the drilled core, inner skin and vac stack all ready to
go. Wet out the outer skin with a fluffy roller/, spread any wet
areas with a squeegee. No need to be too careful. Wet out the core
with a squeegee. Put the core in place and the next layer of glass on
it. Wet it out with the fluffy roller. Remove the protective tape
and apply the vac stack. The trick to long layup times is to spread
the resin quickly. Leaving it in the pot is a disaster. An assistant
to measure and mix resin is a good plan, as is premeasuring the resin
and hardner so they only have to be mixed and stirred.
Use the amount of resin in the absorber material (I use old carpet,
costs nothing) as a guide to how much resin you need to apply next
time. If it goes off too quickly, use slower resin, then throw a
tarp over the vac bag with a couple of blower heaters underneath to
speed it up.
Fitting out and finish are the difference between boats I build and
those built by professionals and proud owner builders. Your shell
will take longer than mine as it is more complex, and you are
learning what you can and can't get away with. My interior will be
bare, to start with, the decks and beam tops will have non slip on
them, the bottom antifouling, and the rest will be bare resin, at
least for the first few months. Partly to show off what can be done
off the table, partly so I can make any adjustments that become
necessary. Suggest you get a breakdown of hours and materials and see
how they compare. It is very difficult for builders to quote using
a new build system, so the more it is broken down, the easier it is to
fine tune the quote.
regards,
rob
