What miter angles do you use for 45 degree crown molding?
by
Judy Looker
We bought crown molding that has two 45 degree angles for the ceiling/wall instead of the usual 38 & 52 degrees. Do you know what bevel angle and miter angle should be used for corners? Thanks, Mike L.

That is a great question Judy, But there is no exact answer to it. There is no real such thing as a square corner in a home. Even being out of square or level can change a perfect square cut into something awful looking when its put on the ceiling. The pros do what is called back cutting. This is where one board is cut square to the wall, Then another is cut at a 45 degree angle then back cut to create a sharp edge that is pressed into the first piece. Doing it in that way allows the wall to be out of square a lot and still get a perfect looking corner that will not open up with changes in humidity, Its a bit hard the first one or two times to do this, but once you get the trick, its faster and easier then cutting both at an angle and trying to match them up when nailing. Here is U tube video on how to do this. We do not use file method explained but its sometimes more easy to those just starting out doing it this way. But if you use the file, be sure to use it correctly. In the video he pushed up from the bottom which is why the wood chipped. Push down from the top using small smooth strokes and do not rub the file up and down, Only push down, remove file and then push down again. Repeat until you have a nice sharp edge. Its important to remove enough wood on the back cut so it does not come into contact with the adjoining piece. Doing it correctly will assure that the joint looks professional. This is how they do stained trim where they cannot "fill" the joints with putty and hide the gaps with caulk. https://www.youtube.com/watch?v=3MT9iVtiOEY

This might help you. When you cut a 90 degree corner you cut each side 45 degrees. Example: 22 corner, 2@11, 45 corner 2 @22.5 etc. Now when you get larger deg corner that you can not move your miter saw enough to one side or the other try this: http://www.creativecrown.com/Large_corners.html Creativecrown.com has the easiest moldings to cut with its flat back design.
