I am trying to fit 5" crown molding (38 degree spring angle) around an
outside bullnose. I've been trying to use a compound miter saw to cut
at 22.5 degrees but have been doing something wrong because I end up
with too small of an angle when I stick the three pieces together.
Can somebody tell me what settings I need to have on my miter saw? I
have the miter set at 22.5. Does the bevel setting also need to be at
22.5? How does one calculate this? Thanks!
Are you cutting the crown molding upside down in the miter saw? With
this arrangement, you should not need to adjust the bevel. Try using
scrap pieces until you get the correct angle. No need to use a
calculator or charts (this is the harder way).
I pickedup this book a few years ago for about $18-$20 .. .. .. money
well spent .. .. .. takes the "mystery out of doing all sorts of trim,
including rouned outside corners.

22.5 will be correct. Turn your crown upside down on the saw with the
flat part on the back of the bottom edge (the part that would go
against the wall) flat against the upright fence on your miter saw.
No need to use the compound feature if your saw will cut through the
molding sitting at that angle on the saw.
You will need to hang past the radius just a little coming from each
direction to make the pie piece work. The first one is the hardest
but you'll get a feel for it.
