What angle do I cut the trim here?
+15
I have sloped ceiling and I can’t figure out how to cut the trim to go on the top of this bookshelf. I’m not doing crown molding, just a half round type trim. I’ve attached a pic of the angle finder numbers and the sloped ceiling. Thanks!
Instructions (hopes this helps)

Oh math and angles, brain bender for sure, ouch! Looks like your horizontal piece would be 153.5-ish degrees, and your sloped piece at the joint would be about 36.5. Definitely use some scrap pieces to test first!
Faddu,
You can find youtubes about how to figure angles without a protractor. I like to make a cardboard template that I can adjust in increments until it fits the angle of the sloped ceiling. I then adjust my mitre saw to match the angle and test fit a scrap.
When in doubt you can always make a paper pattern. Overlap two pieces of paper to match the angle and tape together. Take down and use as a pattern.
Hi Faddu, this video has such a simple but awesome trick you can use to figure out that angel. No maths just two pieces of wood - https://www.youtube.com/watch?v=EyVL2ByubVw
Hi Faddu: Don't over think this thing, which is so easy to do :) What I do when confronted with these types of problems is to take a piece of typing paper, put it on the ceiling edge with painters tape, putting the corner of the paper along the edge where it meets the wall. It should stick there. It will be straight, going down the wall. Then, I put another piece on the wall edge, corner meeting the other corner at the ceiling, and secure it with painters tape, overlapping the 2 pieces. This piece will overlap the ceiling piece quite a bit. Then, I tape the 2 together along the vertical line. You should have a perfect angle then. Remove and make a pattern on something a bit more sturdy or just measure the angle and you should be good to go.
Good luck
OK, First the scale to use is the one that is showing about 27 deg. Divide that in half = 13.5. Set your miter saw at 13.5. Cut two scrap pieces and try the fit. Adjust as required.
Hi Faddu, hope this helps you out,

I can't really explain it but you should use a compound mitre saw in order to cut both angles at the same time.
