Start with the Right Tools for the Job
Some of the tools needed are:
Safety glasses
P
ower miter saw –
We recommend using
carbide saw blade
with 80 teeth
o
r more.
Miter box and hand
s
aw – They have
limited angle
adjustment (not
recommended for
crown).
Coping saw – Only
n
eeded if you choose
the coping technique
to install the moulding.
Angle gage – To create the correct miter, you must
d
etermine the wall corner angle.
Glue – To adhere the miter joints (we strongly
recommend gluing all joints).
Hammer & nails or a pneumatic nail gun.
Other tools may include a tape measure, pencil,
C-clamp, putty and caulk.
Determine the Amount of
Moulding to Buy
You must decide where the
mouldings are to be used and
measure the distances. Make a
list of specific lengths and round
your measurements up to the
next largest foot to allow for cut-
ting and trimming.
Wall Angles
It will also benefit you to measure the wall angles on each
corner. This will help you calculate the correct miter angle.
NOTE: It is not uncommon for corner angles in most
homes to be off as much as 3°. If you were installing 5”
crown moulding the 3° difference would result in a 3/8”
gap in the miter joint. To help you calculate the proper
angle we have an angle calculator listed on our web site.
Calibrate Your Saw
The same principle 3° scenario listed above applies to the
saw. Make sure the saw is square and the table angle gage
is accurate.
Trim Positions –
The way the trim sets on the saw
table and fence.
Vertical position – back of trim is
against the fence.
Horizontal position – back of trim
is resting on saw table.
Compound position – back of trim
is suspended between saw fence
and saw table.
Left and Right hand positioning – the side of the trim you
are cutting is as important as its position on the saw table.
The positions are illustrated above.
Vertical Position Miters
U
se this technique for cutting
baseboard, chair rail, quarter
r
ound, and splice miters.
Inside corners - A left hand
inside corner is shown in the
photo.
Step 1 - To accomplish this, place
the trim on the saw table in the
l
eft hand vertical position and
rotate the angle gage “clock
wise” to 45°, or the desired angle
setting, and make the cut.
Step 2 - To cut the mating piece
simply rotate the table angle
gage to the opposite 45° or desired angle, and place the
next piece of trim on the saw table in the right hand verti-
cal position and cut the trim.
Outside Corners
A Right Hand outside corner is
shown in the photo.
Step 1 - To complete this, place
the trim on the saw table in the
right hand vertical position and
rotate the angle gage “clock
wise” to 45°, or preferred angle
setting, and make the cut.
Step 2 - To cut the mating piece
simply rotate the table angle
gage to the opposite 45° or
desired angle, and place the next
piece of trim on the saw table in
the left hand vertical position.
Horizontal Position Miters
Use this technique for cutting
window and door casings.
Step 1 - A left hand miter is
shown in the photo to the right.
To get the setup in the photo,
adjust the saw table angle to the
“clock wise” 45° or predeter-
mined angle. Then lay the trim
on the table in the left hand hor-
izontal position and proceed to
cut.
Step 2 - To cut the mating piece
simply rotate the table angle to
the opposite 45° or preferred
angle, and place the next piece
of trim on the saw table in the
right hand horizontal position.
After the cut is made the miter
joints are ready for assembling.
