Hopefully you guys can offer some tips for me. Putting in some crown at my dad’s place tomorrow as woodworking is not his forte. Its prefinished hemlock

. I’ve done crown before and have a kreg jig and angle finder but never on a vaulted ceiling. Here’s some pics to show you a couple of the areas.

For a vaulted ceiling, you will need to either:

1. Cut a transition piece at the corner, or

2. “Cheat” the spring angle on the level wall to match the slope of the ceiling. This would require re-cutting the bottom back bevel.

Check out Gary Katz explanation of the transition

Take a piece of scrap and test cut your angles. It will take some time but that will get it perfect.

The runs that go along the angled portion of the ceiling I wouldn’t miter. I’d miter and cope the pieces that run horizontally though. But like said above, your spring angles will probably be slightly different. That’s not a huge angle so I don’t think it’ll be too much different. I hope you have enough scrap for trial and error. I can’t tell what’s going on in that outside corner, if it’s just a straightforard 90 on the same plane….

Get ‘em close, then caulk and paint… only person who will notice it will be you.

Mr Unix has the right idea. My kitchen ceiling was not a perfect plane (didn’t reveal itself until crown molding). Caulk easily filled the gaps, and doesn’t show at all. Much easier than trying to cope the wood to the wonky ceiling, which, by the way, is plaster over metal lath.

It’s a little tougher than that when you’re using “prefinished Hemlock”

Ya if this wasn’t prefinished wood I wouldn’t have even posted this. The transition pieces gave the best look. Turned out ok for my first time on a vaulted ceiling. Good thing any ugly cuts are 11’ high and not noticable from the ground. My parents as more than happy with the results. Thanks guys. And also the ceiling is sheetrock don’t know why you assme its plaster her metal lath especially since its only a 25 year old home.

Dewoof01, He was referring to his ceiling being metal lathe and plaster.

Parents are happy, that’s the main thing. Another step towards gaining experience. The next time will turn out even better.
