jcb JCB-SCMS210 - Crown Moulding Pin Deployment; Compound Cut Settings Chart

1) Twist the moulding pin ¼ of a turn
in either direction to deploy the pin.
2) Pull out and twist ¼ turn in either
direction to lock the pin in the
released position.
Most crown moulding has a top rear
angle (the section that ts at against
the ceiling) of 52° and a bottom rear
angle (the section that ts at against
the wall) of 38°.
In order to accurately cut crown
moulding for a 90° inside or outside
corner, lay the moulding with its
broad back surface at on the saw
table. When setting the bevel and
mitre angles for compound mitres,
remember that the settings are
interdependent – changing one
changes the other, as well.
