Cutting:
When cutting parts with your knife, make your
first cut at light pressure, being careful that the point of the
knife goes exactly where you want it. Subsequent cuts should be
made at moderate pressure until the part is cut out. Use a steel
straight edge to guide the blade when cutting straight lines.
If during
construction you notice the blade start to tear the wood as you
cut, the blade is dull. Replace it with a new blade! A
sharp blade will make cutting easier and will enable you to work
more accurately. Typically, you can expect to use 3 or 4 blades
to build this model.
Using Adhesives:
Although
water-based white glues can be used to assemble this kit, the
Boothbay Lobsterboat has been designed by Midwest to be
built using cyanoacrylate adhesives, CA and Slow CA. These
adhesives cure very rapidly. This will save you a lot of time
and work by eliminating the need to pin or tape many parts
together during construction.
Slow drying epoxy or polyester resin will be used to bond

cloth to the
exterior of the hull. It will also be used to waterproof the
interior of the hull. In this application, these adhesives will
be used as a sealer. The instructions in your kit will tell you
how and where to use epoxy or resin. For now, it is only
important that you understand that epoxy resin and polyester
resin are not compatible! Both of these resins are two-part
solutions that cure by chemical action. If you attempt to apply
one type of resin over the other, chances are that neither will
cure!
Epoxy
resin has the advantage of little or no odor, whereas polyester
resin gives off a pungent odor that requires good ventilation
while it cures. Most epoxy resins are slightly flexible after
they cure and do not possess the strength of polyester resin.
Both resins are only compatible with specific types of paints.
If you have not had prior experience using epoxy or polyester
resin it would be wise to discuss them, along with different
finishing products, with your hobby dealer. I would
suggest the use of epoxy resin over polyester resin.
Polyester resin is far
more hazardous to your health. Often Dumas recommends the
the use of
polyester resin to bond wood decks to their
fiberglass hulls and you may have prior experience with this
type of epoxy.
