Cutting ceiling molding with complex geometry in multiple dimensions

[Allaanvnamnupptagna]

Hello

I've got the lovely task of nailing up ceiling moldings and I'm not quite sure how to saw them so they look okay.

Firstly, the molding has a complex geometry as you can see in the picture.

Secondly, the molding needs to be placed in a corner that has an angle in two dimensions (see picture #2). So it should run through the corner and be 90 degrees to the side as well as maybe 40 degrees in the z-direction.

Is there any trick to solve this, like some caulking or similar that can be shaped, or is there a way to measure this and miter saw it correctly?

The ceiling moulding should therefore run along the paneling slanting downwards and then meet the next moulding in the corner, which then goes directly to the right.

If you need to place the molding where the wall angle is not 90 degrees, you need a different molding.
Like this one.

Are you gray-haired? If not, you will be before you're finished.
My tip is to use a corner block. It will be a bit easier at least.

Googled a bit on your problem and didn't find a solution since many have had your problem. Many did it okay and then used putty, sealant, and paint. You decide, but my tip is as above, a corner block.

Put the crown molding in the ceiling. For the rest, use trim instead.

Did this at the summer cabin, it worked for me.

I split the crown molding to get the sloped ceiling angle, but still made it fit reasonably well with the full-sized molding. However, I had a little larger piece to start with, so it was also split to become a type of crown molding.

Then all the offcuts went according to something like
Oops, completely wrong direction
Oops, completely wrong in the other direction
Oops, too small an angle
Oops, too large an angle

And so on.

Agree with previous writers, set a corner block, you can make it a bit fun at the end with a full fit against the ceiling. Then adjust your molding against the 90-degree angle and set a smyglist on the other angle.

Good luck

The list that runs along the sloping roof must be sawed at the back regardless of whether you use a block or not, then you cut the list like a regular corner with a small intermediate piece.
