views 1 and 2, or it may cover only the portions of the
piece that contain holes or cuts, as shown in views 3
and 4. When holes, cuts, and bends are to be made in
a finished piece, pilot holes, punch marks, and notches
in the template should correspond exactly to the
desired location in the finished piece. Templates for
short members and plates are made of template paper
of the same size as the piece to be fabricated.
Templates for angles are folded longitudinal] y, along
the line of the heel of the angle (fig. 3-39, view 3).
Accurate measurements in making templates
should be given careful attention. Where a number of
parts are to be produced from a template, the use of
inaccurate measurements in making the template
obviously would mean that all parts produced from it
will also be wrong.
Template paper is a heavy cardboard material with
a waxed surface. It is well adapted to scribe and
divider marks. A combination of wood and template
paper is sometimes used to make templates. The use
of wood or metal is usually the best choice for
templates that will be used many times.
For long members, such as beams, columns, and
truss members, templates cover only the connections.
These templates may be joined by a wooden strip to
ensure accurate spacing (fig. 3-39, views 1 and 2).
They may also be handled separately with the template
for each connection being clamped to the member
after spacing, aligning, and measuring.
In making templates, the same layout tools
discussed earlier in this chapter are used. The only
exception is that for marking lines, a pencil or
Patternmakers knife is used. When punching holes in
a template, keep in mind that the purpose of the holes
is to specify location, not size. Therefore, a punch of
a single diameter can be used for all holes. Holes and
cuts are made prominent by marking with paint.
Each template is marked with the assembly mark
of the piece it is to be used with, the description of the
material, and the item number of the stock material to
be used in making the piece.
In laying out from a template, it is important that
the template be clamped to the material in the exact
position. Holes are center punched directly through
the holes in the template (fig. 3-40), and all cuts are
marked. After the template is removed, the marks for
cuts are made permanent by rows of renter punch
It is important that each member or individual
piece of material be given identifying marks to
