Accurate Arch Templates in 5 Minutes or Less
Many arched mouldings require a tracing of the opening in order to
be accurately constructed. These instructions will allow you to create
a tracing that we can use as a template to make your moulding.
1. Start with a clean sheet of paper large enough to cover the
entire opening (window, doorway etc.). The best paper to use is
lightweight brown kraft or white packaging paper, or even heavy gift
wrapping paper. If these are not
available, then you can use products such as Tyvek house wrap or red
rosin building paper. Felt (tar) paper is strongly discouraged. The
lighter weight the paper, the easier it will be to make an accurate
template. A moulding that fits the opening properly depends upon an
2. Stretch the paper across the opening and staple or tack it
every 12" or so close to the edge of the opening. Try to avoid using
tape as this tends to allow the paper to shift during the templating
process. Make sure the paper is flat across the opening.
3. With a small solid object, such as a block of wood, press
along the inside edge of the jamb, making an impression in the paper.
Do this all the way along the jamb opening. The small object should be
held at a slight angle so that the lower edge is gently pressing into
the opening behind the paper, bending the paper around the inside edge
of the jamb. The lighter weight the paper, the easier it is to
accomplish a clean and visible line. If there is a horizontal bottom
edge of the
opening, such as a window sill, turn the corner and continue the line a
couple of inches in from either side so as to identify the bottom of
4. THIS NEXT STEP IS
IMPORTANT. Take a lumber crayon (or a child's
crayon if one is not available), turn it sideways, and carefully go
over the impression on the paper. Do this while the paper is
STILL IN PLACE OVER THE OPENING. Run the crayon over the jamb edge just
did the small block of wood. Keep this line as thin and clean as
possible; if it becomes more than 1/16" wide, use a pencil or pen to
draw arrows showing the actual location of the jamb edge impression.
Also write a note, such as "follow this line" by each arrow indicating
that it points to the jamb edge impression.
5. Write all pertinent information on the template, including:
||A. Indicate what the line traced; this will
usually be the inside edge of the jamb. If it is the outside edge of
the jamb, then also indicate the jamb thickness. A large arrow pointing
at the line with a note saying "THIS LINE IS........." works just fine.
||B. Tell us to make the casing just inside or outside
the line (usually ¼" to the outside if you traced the inside
edge of the jamb) to allow for a proper reveal.
||C. Write the Job Name (or order number), Opening
Location, Moulding Profile and Wood Species on the
||D. If the tracing is of an elliptical (or other
non-true radius) opening, indicate which side of the casing is to face
the line on the paper. This will usually be the back of the casing, but
in some cases could be the front.
PLEASE: (1) DO NOT use
(2) DO NOT submit folded up
(3) DO NOT submit narrow strips of
paper either in a single piece or in multiple pieces taped together.
