Coving sloped ceiling

[HPLIND]

Hello,

Yet another cunning thread about coving and slanted ceilings. I have searched the forum and the rest of the web without understanding how to handle the meeting of the coving from the ceiling to the slanted ceiling. I have twisted and turned in all directions and angles, even first with filler pieces but can't get it right. Is it possible?

Regards,

You measure the angle between the ceiling and the slope. Then you halve that angle and set the saw.

I had the same problem with sloping ceilings and walls. A nuisance for a beginner. Then you take a couple of small pieces and test to see what angle you need, that worked well for me.

You measure the angle between the ceiling and the sloped ceiling. Then you halve that angle and set the saw.


Already tested, resulted in the attached image when cut at 22.5 degrees (sloped ceiling 45 degrees).

Cutting "horizontally." It also doesn't turn out well if cut at the "correct angle."

The left piece looks decent, and the right one should have a bit more angle so the top moves in to the right. If you have an adjustable angle square, take the angle with it and halve it. Then it's important from which direction you saw. Turn the pieces around and have the cove toward the inner angle of the saw. Also, ensure they are flat against the underside and backside of the saw table, the base should rest the same as it will in place. Tricky, I've made mistakes many times myself.

You must place them in the saw as they will be on the wall. So that "up towards the ceiling" becomes up and they stand on edge.

I think it's easier with a hörnkloss, like:

Here is a bit to look at, choose several yourself.

Exactly, the tricky part is how they should be positioned in the saw and on which side of the blade you want to cut. It's understandable, but I started by making test pieces that would fit together at any angle. Then you know how they should be placed in the saw, and from there you can start making test pieces.

How did you approach the meeting point between the ceiling panel and the sloped ceiling? If you're having trouble with the meeting of those two moldings, it won't be easier with an additional meeting from the side.

 

[HPLIND]

Okay, thanks for the suggestions. I think I've tried in all different ways without it turning out well, but I'll try again.

 

[HPLIND]

How are you planning the connection between the ceiling panel and the slanted roof? If you're having difficulty with the junction between those two moldings, adding another connection from the side won't make it easier.

There will be a molding with a simpler angle to manage.

As @sinuslinus mentioned.
Starting from your very first picture:
1. Measure the angle between the roof and the sloped ceiling. Let's assume it's 135°.
2. Set the miter saw to (180-135)/2 = 22.5° to the right, like 1 o'clock (actually a quarter past).
3. Take the left molding in your first picture and place it so that the part against the completely horizontal wall rests on the base plate of the miter saw.
4. Cut off the right part of the molding.
5. Turn the miter saw to 22.5° in the other direction, like a quarter to eleven.
6. Place the right molding in the same way, with the part that will be against the horizontal wall downwards in the saw.
7. Cut off the left part of the molding.

As for making a whole molding that is cut on both ends, that's just forgettable. It will have to be two moldings spliced together.

Edit: In post #4, you placed the left molding the wrong way in the saw.

Hello,

Yet another clever thread about cove molding and sloped ceilings. I have searched the forum and the internet without understanding how to handle the meeting with cove molding from ceiling to sloped ceiling. I have twisted and turned in all directions and angles, even tried with test pieces but can't get it right. Is it possible?

Best regards,

Can you show how you placed the molding in the saw?
And which direction you angled the saw.

Place the molding between the ceiling and the slanted ceiling first. And....... use a simple molding without frills. When you then need to place the molding between the ceiling and the wall, it will be much easier to connect to the previously mounted molding.

Good luck
