Crown Moulding


I am installing Crown mouldling. I want to cut it flat. I want to use a compound miter saw. My corners are 90degrees. My moulding angle spring is 45/45. What is my miter and bevel settings. THanks Wes

Welcome Wes, to the best DIY'r site on the web.

Here is a table of angles needed for crown work.

Since you say all your corners are 90, here is just the section of my chart showing 90 and a few degrees to either side. (BTW, you will be just about the only person in the United States who has corners that are a true 90.)

Thanks for information. I know that is wishful thinking on my behalf. Wes

yep, no walls are perfectly straight, no angles are perfect anything. Those charts will get you in the ball park, but you still need to fine tune. I always have extra trim and make short trial pieces before cutting the long ones.

thank you. This is my first time . All information give is great. I guess it would be to my advantage to cut some sample cuts and label them so I will have a reference. Inside/outside. Is the compound miter the best way to cut laying the moulding flat or should I just miter againt the fence with a 45degree. Thanks

Crown Moulding


Samples will only work for the corner they are fitted to(no two corners will be alike), but can be used as a general guide. But that is a lot of samples to haul around. Once you get the hang of it, you can keep those samples in your head. All outside corners get a mitered joint, inside corners work better with a coped joint, it never opens up like a miter joint can.

Thanks, Never thought about the joint opening up. Thanks again for all your help and knowledge. Wes

Like he said. Cope all inside corners and whenever possible, assemble your outside corners on a table with brads and glue and go up as one piece. Huge time save and you can block behind the miter for more meat to nail into.
