I read the reply to the "Crown Molding Coping" post, but I am not sure I understand. I feel like I am fairly good at hanging molding, using a compound miter saw. However, I am trying to learn how to use a coping saw to get better results.
I believe that you butt the crown molding with a straight cut up against the wall. Then cut the molding going into the corner at a 45 degree angle so that the cut will start to cover up the other piece. What I can not seem to get right is how and how much of the back to you cut off with the coping saw?
Any assistance would be great. Is there any good web sites that have demo's?

you got it right...basically, the answer is "enough"...and "enough" is an angle of about 45 degrees. After butting the 45 cut up to the 90 degrees cut, peek at it and try to visualize how much to cut off so it doesn't hit...try a few to practice...how much gap do you have behind it?...does it matter?...not really...it's the part you see that matters...

When coping, here is what I learned as a finish carpenter.
Yes, cut the piece at a 45' angle. Make sure it's as close to 45' as possible, make sure you set up your compound mitre saw and do some test cuts with scrap wood.
Once you have cut your piece, look straight down on the molding where the 45' cut is. See how the wood still has the crown shape to it at your cut? (***TIP: It may help to run a black marker on the edge of the 45' angle, until you get the hang of this)
Now, take your coping say, and start slowly on the edge of the piece. The balde should be at a 45' angle with the 45' (make sense??)
Slowly cope along the edge of the mitre, following the shape of the mold. Your blade should remain at least at a 45' angle this whole time. More is ok to, like what was said earlier, you can cut off more, all that matters is what is left to the eye.
When you are done coping, there wont be much meat left to the edge of the wood, though you should still see the 45' cut you made with your mitre saw, you don't want to hack that away, rather you want to cut away at what is underneath that.
Keeping your blade at a 45' angle makes sure you cut away enough wood so that the other piece you are going to butt it against, can hide underneath your mitred/coped joint.
Make sense?
