Crown Moulding throughout


Hi Crump!

If I understand your question correctly, you mean the pre-sets on the miter saw, not a table saw - right? You don't require anything larger than 90 degrees as the finished angles for crown molding - inside or outside - are the sum of two smaller angles. No angle can technically be larger than 180 degrees which is a 90 degree straight cut. Beyond that, two smaller angles, depending upon inside or outside cuts, will make up any required angle based upon the way you position the piece to be cut on the saw bed.

If it's "tilt" you're referring to, and if the miter saw has only one side that tilts, then the required angle off from 90 degrees is made by flipping around the piece to be cut. Compound cuts are more difficult to figure out and so there's a terrific softcover book for sale in HD and Lowes that has all of the steps and all of the mathematical degrees tables required to address cuts for both types of crown molding wall angles, i.e. 45-45 and 52-38.

It's entitled Crown Molding & Trim Install it like a PRO! and it's by Wayne Drake.

You basically measure the angle on the wall/ceiling, look it up in the corresponding table and set the saw accordingly. The book also addresses the more advanced cuts for ceilings that rise, along staircases, uneven pillars, progressive columns, etc. You can buy the book along with the companion True Angle angle finders if you wish. It's a blessing to have it along, especially on a large crown job with lots of nooks and crannies and oddball angles.

Good luck!

Hi all,
If you want to do crown molding the easy way...... You need to check out Cut-N-Crown I bought the set a couple years ago at one of the woodworking shows here in Houston and it's something. check out a video on his site, it explains it all. I have no affiliation to him.
