I am putting up crown molding at the top of my kitchen cabinets. When
you are scarf jointing 2 pieces of molding at a 45, do you still cut
the molding on the miter saw upside down with the bottom molding
resting on the fence? ( similiar to doing outside and inside corners?)
I have to join 2 lengths together and was wondering before I cut what
is the correct way.

No. If you've got a compound miter saw, you can cut scarf joints flat
on the bed setting miter angle to 0 and tilt to 45.

If you don't have a compound saw, you can cut them with the molding
vertical against the fence, and use 45. With tall molding, this won't
work.

As previous poster said, it's always a good idea to pick up some cheap
molding (doesn't need to be exactly the same as the good stuff) to
experiment with.
