Compound Mitre (Fig.S, T)
This cut is a combination of a mitre and a bevel cut. This is the type of cut
used to make frames or boxes with slanting sides like the one shown in
figureS.

WARNING: If the cutting angle varies from cut to cut, check that
the bevel clamp handle and the mitre clamping knob are securely
tightened. These must be tightened after making any changes in bevel
ormitre.

WARNING: The saw must be fixed on a base support when
performing compound cuts to prevent tip over. Refer to Bench
Mounting.
• 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.S) 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 this miter angle on saw
Angle of side of box (angle ”A”)
Set this bevel angle on saw
1. Set your saw to the prescribed angles and make a few trialcuts.
2. Practice fitting the cut piecestogether.
Example: To make a four-sided box with 25° exterior angles (angle “A”)
(Fig.S), 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.

WARNING: Never exceed the compound mitre limits of 45° bevel with
45° left or rightmitre.
