CUTTING BASE MOLDING

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.

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.

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 cutline 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 MOLDING

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.

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.

When cutting and installing crown molding 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 molding to help fine tune your saw settings.

Crown molding cutting instructions

For all cuts the bevel angle is 33.85° and the miter angle is 31.62° (right and left).

CUTTING WARPED WORKPIECES

Note: It is recommended that you do not cut warped material.

Sometimes you have no choice but to use a piece of warped material. To cut warped work pieces, make sure it is positioned on the miter saw table with the convex side against the fence. DO NOT place the concave side of the work piece against the miter saw fence; when it is cut it will collapse near the completion of the cut, pinching the blade.

Warning:

To avoid possible serious personal injury and possible kickback, never place the concave portion of bowed or warped material against the fence.
