Vertical Cutting
1. Stand the base moulding upwards with the moulding back
against the fence and moulding bottom sitting on the miter
table.
2. Set the bevel angle to 0°.
3. Turn on the laser and set the miter table to the desired
angle, such as 45° for one half of 90° corners.
4. Align the cut line on the workpiece with the blade and laser
light.
5. Confirm the saw settings, turn on the saw and make the
cut as described earlier.
CUTTING CROWN MOULDING (FIG 28,
29, 30)
Your compound miter saw is the ideal tool for cutting crown
moulding, which bridges the wall and ceiling. The most common
style of crown moulding used today has a top rear angle of 52°
at the ceiling and a bottom rear angle of 38° where it meets the
wall. For an installation with tight fitting corners where the right
and left pieces meet, extremely accurate bevel and miter angle
settings are required.
There are two methods for cutting crown moulding. 1) Cutting
Crown Moulding Flat on the Miter Table. 2) Cutting Crown
Moulding Vertically Nested against Miter Fence.
Cutting Crown Moulding Flat on the Miter Table (FIG 28)
Since the most common corners encountered when using
crown moulding measure 90° inside and outside, the following
instructions will be for cutting 52°/38° crown moulding to fit 90°
corners with the moulding laying flat on the saw table.
NOTE:
When cutting and installing crown moulding keep in
mind the bevel and miter angles involved are extremely accurate
while the corners you'll be working on will rarely measure exactly
90°. Therefore, be prepared to make numerous practice cuts with
scrap moulding to help fine tune your saw settings.
