• When you see the term “cut and fit” in the
instructions, it means you should first position the
part on the assembly without using any glue.
Slightly modify or shape the part as necessary
for the best fit.
• Whenever just “epoxy” is called for, you may
use
either 30-minute epoxy or 6-minute epoxy.
When 30-minute epoxy is specified, it is highly
recommended
that you use only 30-minute
epoxy because you will need either the working
time or the additional strength.
• During construction you will be using a number of
balsa sticks to frame various assemblies. Ample
material is included but you should study the plans,
then make an effort to cut the longest pieces you
will need first. Label the pieces for later reference
as you cut them. By doing this now, you won’t have
to splice pieces together later.
• Do not throw away any leftover material until
after you have completed your model. Some
small pieces of leftover balsa or plywood are
used during construction.
• This kit is built with three types of glue.
Cyanoacrylate - CA glues cure almost instantly
and are moderately strong. There are three
common types used: thin, medium and thick.
Thin cures the fastest but will not span gaps
between parts. Medium and thick are used
where parts do not fit perfectly. CA glue does not
bond well to most plywoods and hardwoods. CA
glues are also brittle.
Aliphatic Resin - Resin glues require that parts be
pinned or clamped together while the glue
dries–typically 15 - 30 minutes. Resin glues
are ver y strong and work well with balsa
and plywoods.
Epoxy - 6-minute epoxy cures the fastest; it sets
within six minutes but is not fully cured for one
hour or more. 30-minute epoxy is the strongest
as it allows the epoxy to soak into the wood
thoroughly. While it sets within 30 minutes, it is
not fully cured for two or more hours.
Throughout the assembly of this model, THIN CA
should be used unless the step calls for another
type of adhesive. If your parts do not fit well,
substitute MEDIUM or THICK CA.
