A compound miter is a cut requiring both a miter setting and bevel setting A compound miter is used for making frames or boxes that have sloping sides and are wide at one end and narrow at the opposite end, Compound miters are "tricky" to make because the miter setting and bevel setting are directly related to each other Every time the miter setting is changed the bevel set- ting must also be adjusted; likewise every adjustment to bevel requires a corresponding adjustment to miter, Because it may take several tries to obtain the desired angle it as advisable to make test cuts in a scrap piece of material.
Cutting Crown Moldings
Plan Ahead so that you are not tempted to reach across saw blade to steady newly severed workpiece
Two Methods to Cut Crown Moldings
1, Workpiece standing up, usua!ly cut inverted from ceiling mounted orientation. Fixturing: Accessory mounted crown molding jigs which locate workpiece See recommended accessories (Table clamp is helpful) Hand is on fence when the cuts are made. All cuts are made at 0 ° bevel setting (see illustra- tion).
Alternate fixturing: Auxiliary fence as shown on page 19 plus table clamps.
2. Workpiece lying flat for compound cut (see chart),

PRETESTING COMPOUND SETTINGS ON SCRAP MATERIAL IS EXTREMELY IMPORTANT!
A compound miter saw is excellent for cutting crown molding. Crown molding is difficult to cut because in order to fit correctly it must be precisely mitered,
All Standard (US) crown molding has a top rear angle (fits next to ceiling) of 52 ° and a bottom rear angle (fits against wall) of 38°
NOTE: Above angles assume that the constructed wall corner is exactly 90" In typical construction, this is not always the case. Measure wall and make necessary adjustments to angles
