Cutting Picture Frames, Shadow Boxes And Other
Four-Sided Projects (Fig. R, S)
Try a few simple projects using scrap wood until you develop a "feel" for
your saw. Your saw is the perfect tool for mitring corners like the one shown
in Figure R.
Sketch 1 in Figure S shows a joint made with the bevel adjustment method.
The joint shown can be made using either method.
• Using bevel adjustment:
- The bevel for the two boards is adjusted to 45° each, producing a
90° corner.
- The mitre arm is locked in the zero position and the bevel
adjustment is locked at 45°.
- The wood is positioned with the broad flat side against the table
and the narrow edge against the fence.
• Using mitre adjustment:
- The same cut can be made by mitring right and left with the broad
surface against the fence.
Cutting Trim Molding and Other Frames (Fig. S)
Sketch 2 in Figure S shows a joint made by setting the mitre arm at 45° to
mitre the two boards to form a 90° corner. To make this type of joint, set
the bevel adjustment to zero and the mitre arm to 45°. Once again, position
the wood with the broad flat side on the table and the narrow edge against
the fence.
The two sketches in Figure S are for four-sided objects only. As the number
of sides changes, so do the mitre and bevel angles. The chart below gives
the proper angles for a variety of shapes, assuming that all sides are of
equal length.

For a shape that is not shown in the chart, use the following formula: 180°
divided by the number of sides equals the mitre (if the material is cut
vertically) or bevel angle (if the material is cut laying flat).
Cutting Compound Mitres (Fig. T)
A compound mitre is a cut made using a mitre angle and a bevel angle at
the same time. This is the type of cut used to make frames or boxes with
slanting sides like the one shown in Figure T.

WARNING: If the cutting angle varies from cut to cut, check that the
bevel lock knob and the mitre lock handle are securely locked. These
must be locked after making any changes in bevel or mitre.
The chart shown below will assist you in selecting the proper bevel and
mitre settings for common compound mitre cuts.
• Select the desired angle A (Fig. T) of your project and locate that angle
on the appropriate arc in the chart.
• From that point follow the chart straight down to find the correct bevel
angle and straight across to find the correct mitre angle.
• Set your saw to the prescribed angles and make a few trial cuts. Practise
fitting the cut pieces together.
Example: To make a 4-sided box with 26° exterior angles (Angle A, Fig. T),
use the upper right arc. Find 26° on the arc scale. Follow the horizontal
intersecting line to either side to get mitre angle setting on saw (42°).
Likewise, follow the vertical intersecting line to the top or bottom to get the
52
bevel angle setting on the saw (18°). Always try cuts on a few scrap pieces
of wood to verify the settings on the saw.
Cutting Base Moulding (Fig. K, U)
To complete straight 90° cuts, position the wood against the fence and hold
it in place as shown in Figure U. Turn on the saw, allow the blade to reach
full speed and lower the arm smoothly through the cut.

Cutting Crown Moulding (Fig. A1, V1, V2)
Your mitre saw is well suited to the task of cutting crown moulding. In
order to fit properly, crown moulding must be compound mitred with
extreme accuracy.
Your mitre saw has special pre-set mitre latch points at 22.5°, 31.6° and
35.3° left and right for cutting crown moulding at the proper angle and
bevel stop pawls at 22.5° and 30° left and right. There is also a mark on
the bevel scale
cutting crown moulding.
nOTE: Pretesting with scrap material is extremely important!
