CUTTING BASE MOLDING (FIG 26)
Base molding can be cut using two methods: standing vertically against the fence or horizontally, laying flat on the
miter table. Using the vertical method is limited by the height capacities of your compound miter saw.
Flat or Horizontal Cutting:
1. Lay the base molding's back onto the miter table with the
bottom of the base molding placed against the fence.
2. Set the miter angle to 0°.
3. Turn on the laser and set the blade's bevel 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.
Vertical Cutting
1. Stand the base molding upwards with the molding back
against the fence and molding 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 work piece with the blade and laser
light.
5. Confirm the saw settings, turn on the saw and make the cut as
described earlier.
CUTTING CROWN MOLDING (FIG 27, 28,
29)
Your compound miter saw is the ideal tool for cutting crown
molding, which bridges the wall and ceiling. The most common
style of crown molding 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 molding. 1) Cutting
Crown Molding Flat on the Miter Table. 2) Cutting Crown Molding
Vertically Nested against Miter Fence.
Cutting Crown Molding Flat on the Miter Table (FIG 27)
Since the most common corners encountered when using crown molding measure 90° inside and outside, the
following instructions will be for cutting 52°/38° crown molding to fit 90° corners with the molding laying flat on
the saw table.
