I have to install some shelving in a room with an angled ceiling. There will be a cove molding at the top. The angle of the ceiling to the wall is 73.6 deg (or 16.4). the cove is shop-made about 2 1/2″ wide and will sit 45 deg. to the top face frame and the ceiling. I will use a DeWalt CMS. How do I figure the angle settings to cut the top and bottom angles of the molding? The molding is in a straight run, in two pieces, ~16′ total.
Is there a website that gives that info or calculates it for you?
Thanks!

If I understand you correctly, you won't have to cut the bottom angle because it presumably has been made to attach to the face frame so that it gives you the projection and angle you want. So you only have to remove material on the top so the front face meets the ceiling. Take a bevel and set it to the angle made by the plane of the face frame and the plane of the ceiling. With the base of the bevel held flat against the surface that will contact the face frame, mark the edge of a test peice so the angle intersects the place where you want the moulding to touch the ceiling. Now reset the bevel so it registers that line from the flat back of the cove. Set the table saw to that angle, set the fence to the right width and there you go.
I guess I didn't make myself quite clear. The ceiling slopes left (high) to right (low). The top of the shelves match the slope. The cove will sit "flat" on the face frame and "flat" on the ceiling. (at a 45 deg. to both). I need to cut the angle at the high end and the low end.
Am I thinking too hard, or will this be a compound angle cut?

My guess would be you're not thinking hard enough. <G>
Shouldn't have to be a compound cut if you cut the angle with the crown placed on the saw as it would be on the wall. Upside down, of course :-)
