Assuming my diagram uploaded.
Want to run crown (or cornise) against rake board underneath soffit.
8:12 gable end wall.
1) I believe for the two pieces to meet in the middle at the peak, if I can ‘stand’ the crown up I would set the chop saw miter to 56.3 degrees? If the crown won’t fit standing up how would I determine the compound angles require?
2) This gable end prodrudes out beyond another 8:12 pitch below it that is running down and away from beneath the gable end in question. The entire soffit of this gable end is ‘flying’ out there.
Ergo the bottom end of the rake board will have a 33.7 degree cut.
I would like to ‘return’ the crown where it ends at the lower end of the rake board such that the ‘return’ piece is essentially horizontal.
Is this possible, and if so how do I determine the compound angle cuts short of trial and error.
Let’s not confuse the issue with facts!

I saw your drawing in your other post, I resized it and posted it here.

Peace in.
I'm doing a similar detail right now. I assume you are cutting this crown on the flat? First you need to figure out the angle your crown sits at (usually either 38/52 or 45/45). figure the angle of the corner your fitting the crown into (for the peak of the roof, it would be 2x the plumb cut I believe) then use one of these charts to figure out the miter and bevel settings on the saw.

A construction master calc. with the trig functions can also figure this as well. Good luck.
Also, why return the crown at the rake/lower roof? Why no just cut the crown to the roof angle and let it sit a bit up off the lower roof. You could also put a pitch block in the end of it so no critters take up residence.
