17. Ship's Name
The Rattlesnake name should be lettered on
the surface of the stern. The neatest way to
add this detail is to use dry transfer letters.
These can be purchased at a number of art
or office supply stores. After applying the
lettering, paint over the letters with a coat
of flat varnish. You can also find decal lettering from model railroad stores.

18. Ship's Longboat
The ship's longboat model is unique. Instead of the usual Britannia casting or
solid block boat found in most kits, this
kit has laser-cut wood lifts for breadand-butter construction (see figure 41).
You will be doing some carving, and will
be faced with a challenge: how thin can
you carve the hull without breaking it?
Carving a small boat hull is difficult. A
way to check the thickness of the hull is
shown (see figure 42). This is a homemade double-ended caliper. You can
also buy metal ones commercially.
There are end tabs on each lift to assist
with the alignment. The wide tab is the
stern and the narrow tab is the bow.
Each lift from tab end to tab end is the
same length. As you glue up the lifts
keep the tabs in line. Use only a thin
coat of glue. If you get too much glue on
each lift, the thickness will accumulate
and the overall height of the glued-up
lifts will be too great.

Gap "A" must equal gap "B". If ends do not touch,
sand one end until both ends touch (zero gap)
Carve the inside of the boat first using
chisels and sandpaper. Carve or sand the
corners of the lifts down to the intersection of two lifts. When all is smooth, the
shape should be reasonably correct. Next,
cut off the tabs and carve the hull to the
correct profile. Then carve or sand the outside form. Be careful; the hull will be getting thin. Make some templates from the
body lines shown on the plans to get the
shape correct. Add the keel and rudder
and you will be done with the basic hull.
Carving Option: It may be easier to carve
the inside of the boat hull by temporarily
leaving off the bottom lift. Carve the inside
close to what is required, then glue on the
bottom lift and complete the carving.
How far you want to go with detailing
is up to you. You can add bottom
boards, frames, thwart knees, and gunwale molding. All these details add to
the model, but will be a little difficult. If
you do it, always keep the scale in mind.
This is a delicate boat. Make the thwarts
1/64" thick (sand down a 1/32" piece).
