I trying to install some crown molding. There will only be outside
corners, and all corners are 45 degrees. The crown molding must be
installed upside down so that the 38 degree angle is at the top and
the 52 degree angle is at the bottom. It has to be installed upside
down so the top can span a certain distance out. I am having a heck of
a time getting this.

The corner I'm testing on is exactly 45 degrees, left outside corner.
The book I'm working with says 33.85 B and 31.62 M. Because I'm
installing upside down do these numbers mean anything in my situation?
Should I toss them and just figure it out with trial and error? Should
I swap the numbers? Is there a formula I could use to figure this out?
I've burned through a lot of rough stock and I'm no closer.

Any help is appreciated.

Use those numbers...do'nt swap them, swap the part...if you would normally
put the lower edge of the molding to the fence, put the upper edge to the
fence instead.
