Machine screws are designated by a number, threads per
inch, and a length. For example 4-40 x 3/4" [19mm].
This is a number four screw that is 3/4" [19mm] long with
forty threads per inch.
• When you see the term test fit in the instructions, it means
that you should first position the part on the assembly
without using any glue, then slightly modify or custom fit
the part as necessary for the best fit.
• Whenever the term glue is written you should rely upon
your experience to decide what type of glue to use. When a
specific type of adhesive works best for that step, the
instructions will make a recommendation.
• Whenever just epoxy is specified you may use either
30-minute ( or 45-minute) epoxy or 6-minute epoxy. When
30-minute epoxy is specified it is highly recommended that
you use only 30-minute (or 45-minute) epoxy, because you
will need the working time and/or the additional strength.
• Photos and sketches are placed before the step they
refer to. Frequently you can study photos in following steps
to get another view of the same parts.
• Not all die-cut parts have a name, or their complete name
stamped on them, so refer to the die drawings on page 7 for
identification. When it's time to remove the parts from their
die sheets, if they are difficult to remove, do not force them
out. Instead, use a sharp #11 blade to carefully cut the part
from the sheet, then lightly sand the edges to remove any
slivers or irregularities. Save some of the larger scraps of wood.

• The easiest way to cut balsa sticks is with a single-edge
razor blade or razor saw. Position the stick over the plan,
mark its size, then cut the part on a piece of scrap wood. A
modeling miter box works well for cutting square corners
and 45° gussets.
