88° ÷ 2 = 44°
Step-by-Step Step-by-Step
Determing the type of cut based on the corners
of your walls.
How you will position the Crown-Pro TM in relation
to your saw, and how you position your saw will be
determined by what type of cut you will be making.
(See Step 5)
There are 4 types of cuts: Inside Corner-Left,
Inside Corner-Right, Outside Corner-Left, and Outside
Corner-Right.
Each corner has a right and left side determined by
your right and left as you look at it. An inside corner
is when the wall corners go away from you and an
outside corner is when the wall corners come
towards you.
Use the Angle Finder to calculate the
necessary saw angle
Before each corner cut you make, it’s important to fi nd
the angle of the wall before setting your saw. Often times
your corner angle will be off by a few degrees, resulting
in a gap between the molding if you don’t properly
compensate with your saw. In this example, the corner
turned out to be 88°, or 2° short of 90.
If you have a Miter saw which reads 90° at the front,
you’ll simply divide the wall angle (88°) by 2, to get a
saw angle of 44°. (See Example A)
If you have a Miter saw which reads 0° at the front (the
majority of miter saws), you’ll add one more step to the
process. Instead of dividing the “Wall Angle” by 2, you’ll
have to divide the “Spring Angle” by 2. In our example,
with the Wall Angle being 88°, the Spring Angle reads
92°. If you divide this by 2, you get a saw angle of 46°.
