Crown molding angle
Hi,
I'm as green an amateur woodworker as you can get. I've been teaching myself crown molding, and done a fairly decent job in my kitchen, but now I've hit this reverse 135 degree or whatever angle and can't figure out the correct angles to cut my molding at. I think I've burned thru about 30' molding thru trial and error. Help on how to correctly do this? Photos attached. Thanks for any help!!!!!

THIS is just one answer.
If you "google" HOW TO CALCULATE CROWN MOLDING ANGLE you will get many answers.

Buy an angle gauge at home depot. Even the $5 plastic one can work. Measure the angle, divide it by 2 and that's the angle you need to cut. If using a compound mitre saw subtract 90 from that number...this number will be what you set the saw to make the cut.

Agree, measure the angle and divide by two.
Also, I like the method of cutting it upside down. You set the ceiling side on the table of the miter saw. The right side piece is cut from the left side of the blade, and vice-versa. Then you don't have to worry about the compound angle, just the angle of the corner. This is a lot simpler for those of us who don't do trimwork that often.
Another tip would be to use two small scrap pieces to dial in the angle, before you start on the really long ones.

From the picture it appears to be a 135 degree obtuse angle. If that is the case the angle of the joint is 45 degrees which would make each molding a 22.5 degrees angle. I agree with sanchez use a couple of scrap pieces of molding to work out the angle.
I found a piece of crown molding in my shop and tried it. What that would mean on a compound miter saw tilt the blade over at 15 degrees and cut left and right at 15 degrees.
