Crown molding cut, 70* Cut how?

I have a crown molding cut to make that I just can't figure out how to make. It's a 140 degree inside left inside right. So the miter saw has to be set to 70 degrees. How do I cut this with a miter saw that only handles 50 degrees at most. The crown is a 6" 45* spring angle. I have no problem with crown that is 50* or less but just can't figure out how to make this cut!
Thanks in advance, Rich

Cross posting is OK. Multi-posting is NOT OK on any newsgroup! Read your FAQs if you want to know why. Else you could quickly find youself ignored jsut about anywhere you post. Use the groups to your advantage or they'll end up a disadvantage.

Your answer did not fit my application and would have been totally impossible for me to achieve. I found the answer to my question not on any newsgroup or google. I figured since I do visit both groups and have given my answers to questions on both and your answer and others who didn't have a clue would not work that it would not be a problem asking others.
I did read the faq on crossposting and multiposting and still don't completely understand what the problem is. If I can't get the answer to a question on one group then I'll go to another. I may not have the time to sit and wait for the right person to come around and share his knowledge.
Sorry for the misunderstanding. Rich

Instead of trying to make a miter cut you can do it by hand with a coping saw. One piece goes flat against the wall and the other is "coped" so that when they fit together you can't tell the difference between it and a bon-a-fide miter joint. I don't want to leave you hanging, I can do it, but I don't think that I can do a good job of explaining how to do it. Hope some on jumps in and describes it for you. MLD

I never cope crown, I always miter it. I do cope base molding though. So there is no need to explain how to cope. You can't even see the joint when I put the two together using the compound miter joint.

understand your reply.
The simplest example is quarter-round meeting at an inside corner. Cut the left one flat and put it right into the corner. The right one should have a quarter round cut out of it, perpendicular to the piece of wood,itlself and parallel to the first piece that went in on the left

We had an assignment in the 8th grade to explain something mechanical. I tried a simple mechanical can opener, and it was incomprehensible. Another guy tried a lock cylinder, and even though I hadn't known how they worked before, I did after he read his description, (which was no longe than mine.) I think I'm better than I was in the 8th grade, but I'm not sure. :) .

First of all you are using the old saying "Divide the corner angle by 2". This is correct if your saw has what is called a face angle miter scale, 90 deg in the front +/- 45 deg. If your saw has this type of scale then you would set your miter on 70 degrees and prop the crown upside down with the bottom of the crown held in full contact (very important) with the fence to make the cut.
However if your saw has a standard miter scale (most common) with 0 degrees in the front +/- 45 degrees then you would set your saw on 90 - 70 = 20 degrees.
If you wish to cut your crown laying flat and face up then the saw setting for 140 degree corner and 45 degree spring angle is Miter = 14.4, Blade tilt = 14.0 degrees.
