A pic of the obstruction would be nice?
I don't have a picture, i can try a little diagram but these things don't usually turn out too well:

The image seems clear to me. I believe he has a room that has a section of the wall going up at an angle because there are stairs on the other side of the wall. So basically this will be an outside corner, where one wall is 90 deg to the ceiling and one wall angled. Coping this is not really an option.
If you have a CMS or tablesaw you can test using scrap 2x lumber. I've never had to install molding on such a wall, but since the crown does not have a slope angle, it seems to me that the piece on the strait wall would need to be beveled at 45 deg and mitered at the angle of the wall. The piece on the angled wall would be just beveled at 45 deg. Of course since the wall is not at 90 deg to the ceiling, you are going to have a gap between the molding and the ceiling:
Then again, I might be totally misunderstanding your question. :)
I think you understand my problem correctly. But the issue seems to be, when you miter the molding at a 34 degree angle, the length of the cut edge is maybe 10". If I just bevel the return at 45 deg., I will be trying to line up a 10" edge with a 6" edge. When I cut the return at a 34 degree angle also, it seems to go in a different direction (down from the ceiling, instead of back towards the wall). Which makes me think I am not orienting the return piece correctly on the CMS when i cut it. But I have tried turning it around, upside down and backwards, and I still can't get it to work.
As Sir Ben pointed out, a pic of the location would help. Post it in the binary group if you can sanp one. Otherwise, I think you will be dealing with splitting the angle. Run a line on both planes and then interesct them and that is your cut lines. If you are trying to Return the piece that is on the 34' slope, your Return cannot be level......is that the issue? Based on the images on the website you should be able to handle it like any other Crown.

Those last two sentences describe pretty closely what happens when _I_ have done crown moulding. I usually try to buy more than enough. Sometimes, I succeed.
Hold it up to the wall. Draw lines on some scrap pieces, then go make test cuts. Cuss under your breath. Do it again until you have it right. ;-)

It's hard to understand exactly what your issue is, but it sounds a bit to me like you are making a corner and starting a slope all at the same time?
I don't have the exact answer but I just did a search using "cutting crown molding" and came up with many sites that show how to make some of the "weirdest" cuts you'll come across. There were sites that had tables for the miter and bevel angles needed for various applications (i.e. cathedral ceilings).
The cathedral ceiling one appeared to best fit what you're trying to do
It is not possible. The only return that works would be square to the plane of the sloped ceiling.

The cut pieces can match up properly only if the lengths of the cut edges are equal. The only way to make that happen is to cut each of the pieces at 1/2 the angle between them.
BTW, a good way to avoid confusion with questions like this is to take a digital photo (borrow a friend's camera - and friend - if necessary) and post an article with photo attached to the news:alt.binaries.pictures.woodworking newsgroup.

Okay, I still haven't figured it out, but I have taken a couple pictures:
Does this clarify the situation? Any new suggestions? Thanks!
I believe your best bet will be to *fill in* the angled slope first so that it resembles a standard plumb wall. The molding is made for a 90 degree (ceiling/wall) application, so you are not going to be able to intersect those angles unless you build out the 37 degree void.
Yes,it cannot be done the way your are thinking,you're going to have put a square section so that it hangs down at 90 degrees to the wall. And to be honest this will look a lot better.
It cannot be done- the only return that works is a standard 45. To clarify, imagine a 1x4 in place of the crown (placed flat against the wall). After you mitered it at a 34 degree angle with a 45 degree bevel, the stock width needed for the return to the wall would be
4.22" rather than 3.5" (and two additional cuts would be needed to keep the top and bottom on the same plane). If you ignore the top and bottom problem, you would need a piece of crown with a profile "stretched" to 120% of the stock profile for a 34 degree return to work.Ted
