molding miters on a compound miter saw
John S. Stacy, via e-mail:
How do you cut crown moldings on a compound miter saw? I have
been told to put the molding upside-down on the saw. Can you explain?
I want to cut inside and outside corners.
The back edge of crown molding has a built-in bevel at the top and
the bottom. These bevels (or flats) allow the molding
to sit at an angle against the ceiling and the wall when the molding
cut the molding, place it on your miter saw with its face toward
you. Rest the top bevel (on the back side) flat against the vertical
fence of your miter saw....and the bottom bevel flat
against the horizontal table of your miter saw.
you place it in position, rock it back-and-forth until you feel
it resting solidly on these flats before you make your cuts. Hold
your molding firmly in position against the flats and make your
resting these bevels (or flats) solidly against the
back-up fence and table surface during the cuts, you'll be sawing
your molding at the same angle as when it's resting as intended
against the ceiling and wall. There's no need to put the molding
upside-down on the saw.
