Cutting picture frames, shadow boxes & other four sided projects
(fig. Q1 & Q2)
Trim moulding and other frames
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 fig. Q1. The joint shown has been made using either bevel
adjustment.
- 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. 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.
The two sketches (fig. Q1 & Q2) are for four side 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,
divide 180° by the number of sides to determine the mitre or bevel angle.
No. of sides Angle mitre or bevel

Compound mitre (fig. R1 & R2)
A compound mitre is a cut made using a mitre angle (fig. Q2) and a bevel
angle (fig. Q1) at the same time. This is the type of cut used to make
frames or boxes with slanting sides like the one shown in fig. R1.
If the cutting angle varies from cut to cut, check that the bevel
clamp knob and the mitre lock knob are securely tightened.
These knobs must be tightened after making any changes in
bevel or mitre (fig. R1 & R2).

These knobs must be tightened after making any changes in

The chart shown below will assist you in selecting the proper bevel and
mitre settings for common compound mitre cuts. To use the chart,
select the desired angle “A” (fig. R2) 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.
Practice fitting the cut pieces together.
Example: To make a 4 sided box with 25° exterior angles (angle “A”)
(fig. R2), use the upper right arc. Find 25° on the arc scale. Follow the
horizontal intersecting line to either side to get the mitre angle setting
on the saw (23°). Likewise follow the vertical intersecting line to the top
or bottom to get the bevel angle setting on the saw (40°). Always try
cuts on a few scrap pieces of wood to verify the settings on the saw.
Cutting base mouldings
The cutting of base moulding is performed at a 45° bevel angle.
Always make a dry run without power before making any cuts.
All cuts are made with the back of the moulding laying flat on the saw.
Inside corner
- Left side
Position the moulding with top of the moulding against the fence.
Save the left side of the cut.
- Right side
Position the moulding with the bottom of the moulding against the
fence.
Save the left side of the cut.
Outside corner
- Left side
Position the moulding with the bottom of the moulding against the
fence.
Save the right side of the cut.
- Right side
Position the moulding with top of the moulding against the fence.
Save the right side of the cut.
Cutting crown mouldings
The cutting of crown moulding is performed in a compound mitre. In order
to achieve extreme accuracy, your saw has pre-set angle positions at
31.62° mitre and 33.85° bevel. These settings are for standard crown
mouldings with 52° angles at the top and 38° angles at the bottom.
Make test cuts using scrap material before doing the final cuts.
All cuts are made in a left bevel and with the back of the moulding
against the base.
