I need help figuring out the correct angles and cuts for a sloped wall. Please note that it’s a sloped wall and not a vaulted ceiling.
Wall 1 – standard 8 ft wall with 90 degree angle between wall and ceiling
Wall 2 – underside of stairs. Wall 2 intersects wall 1 at 90 degrees. Slope is 45 degrees.
I’m a home DIY’er but I’ve done mitered and coped insided corners, outside corners, and used corner blocks as well. I just can’t figure this one out.
What are the angles and cuts if:
option 1: molding runs along wall 1 and terminates at the intersection of wall 2. No molding on wall 2.
option 2: moulding runs along wall 1 and wall 2…but then either terminates on wall 2 (return miter) or wraps around wall 2 to wall 3 (it’s the stairs.)
The stairs have a hallway next to them and the basement door/stairs underneath. Thanks in advance for your help.

Crown Moulding Angles
emaxxman00,
There are some things that "can't be done" with crown moulding. What I mean is that sometimes the compromises that are required to get the moulding to follow angled ceiling/wall lines defeat the end effect desired.
Although you've spelled out the conditions you are faced with I'm not sure I understand the configuration you're describing. I'm willing to work with you in answering your question using Google SketchUp as a topic in The Digital Jobsite here at finehomebuilding.com. Is there some way you can post a digital photo of the area you describe? I would also need to know the size and spring angle of the particular moulding you are working with. This post:

will give you an idea of the process I'm suggesting.
Or maybe someone a little sharper than me can anwer this quicker :-)

I am cornfused also, but know that in this case-a picture would be worth a whole lot of words.
Transitioning crown form a horizontal wall to a sloped wall
You need to create a transition piece between the crown on the horizontal wall to join up with the crown on the sloped wall. I can't tell you how to do it, but a couple of years ago, I saw someone doing it at a workworking show. There was a booth with a product called cut n crown. It was a jig for cutting crown. Kreg makes something similar now. Check out their web sites, http://www.cutncrown.com or http://www.kregtool.com on how to do what you need.
Luckily
you evidently know what he's talking about.
Fill us in.
Calvin,
You cope the piece that goes on the slope, then cut a 22 1/2 on it to the short point of the cope. That leaves a small piece the turns half the angle. Cut a 22 1/2 on the next upslope piece. 22 1/2 cuts are cut with the crown laying flat ( I think). Easy to do ,hard to explain.

I'm still confused about this "sloped" wall. without a vaulted ceiling.
His first wall is "normal"-runs 90 deg. to the ceiling.
this sloped wall, runs ..........................
what'd he say-45 to the ceiling?
and it's not a vaulted ceiling.
stairwell meets the verticle wall
I think what he has is the top of the wall below a framed in stairwell above, so the ceiling/wall is coming up at a 45-degree angle to meet another wall at the roof line.
A few pictures would really help.
Jigs,
My way would work with that except the coped transition piece would have the point of the pie shape on the bottom.
45 is too steep for stairs, should be around 30. Maybe that's why the cut is off.

Thanks to you two.........
I've got the idea now. He confused me with "not a vaulted ceiling"
But now that I think about it-I'm still confused. Is the ceiling sloping at that angle? And where does that "ceiling" end?
Gimme a picture-I'm dumb as a stump.
EDIT: Sorry, I see now. We went through this same thing (sort of) with Gene-the upstate NY builder in a room with dormer windows.
Because of the angle of the Ceiling at the point of stairwell beginning, I'd opt to drop a mini bulkhead plumb down to just below the crown. Otherwise, how would the crown lay on that "angled wall" which to me is really a vaulted ceiling........................
Still just a dumb carpenter..................
Hi everyone, sorry for not getting back to this post quicker. Work has been crazy and I haven't had a chance to get back to this.
Here is a pic of what I have (this is not my room though).
http://www.diychatroom.com/f14/crown-moulding-flat-ceiling-angled-wall-question-43318/
The spring angle is 45 degrees. I simply want to terminate the crown into the slant.
I"d terminate or "I'd opt to drop a mini bulkhead plumb down to just below the crown". This would put the crown on the same plane around the stairwell. Paint out that bulkhead the wall color so you lose it to the eye. Size it so you have just a small reveal under the crown.
Hi Calvin...thanks for the reply but how do I figure out the angle for the crown cut if I"m terminating it? I can't seem to get the cut correct.
Take a pc of crown and hold it up there (tack if necessary) Take and scribe the angled "wall" onto that pc.
Now, I cut crown upside down and backwards-I could cut to that line I made on the mitresaw by placing it on the saw as it sits on the wall (but upside down and backwards-the base of the saw is the ceiling/the back fence is the wall.)
If necessary, I'd add a shim of sorts to the back to be able to cut an angle greater than the saw can cut.
Would it work to rip the crown as thin as possible and lay it flat against the angle? Maybe with a small shoe mold or such below to hide the bottom edge.
It's worth a try.
But I don't think the look would appeal to many. Frankly, it would look like a pc of crown laying flat.
Yeah, I don't care for crown in the first place, so I'm no judge as to how it woulld look. Might be worth an experiment, though.
"Mini bulkhead" would get my vote, I think. (now with drawing)
I just took a look at the photo, and I think that in this case continuing the crown around the stairwell would look better than having it die into the slope. Rip a piece of wood to the angle of sloped ceiling to visually extend the bottom of the crown back to the slope.
Jim
I wouldn't die it into the slope either, but he's asking for how to get the angle right so he can mock up a pc to get the visual.
Now, to your suggestion which I'm a bit unsure of - "Rip a piece of wood to the angle of sloped ceiling to visually extend the bottom of the crown back to the slope."
Could you explain that a bit further?
thanks.
Just his way of achieving the "bulkhead", I think -- a triangular piece of wood.
Very crude drawing attached--
Whether this would work will depend on the size of the crown molding, but I think that if the crown is carried around the entire perimeter, the added wood will not be particularly noticeable.
Personally, I'd probably mock up a couple of variations and see what looks best before investing too much time or trouble.
PS--No, I haven't seen any crown molding like the shape shown in my drawing in stock anywhere. For good reason.
To mock up the angles I'd make cardboard templates. And for cutting the complicated angles I'd make a jig to hold the crown at its spring angle, even if the regular corners were done with a compound miter.
Thanks everyone for your input. It's been a pretty interesting discussion. I found a few pics with and without the builkhead. To be honest, I didn't really like the look of either. In the end, I went with simply terminating the crown intot he slant. I can the bulkhead later if I decide to.
Regarding the angle, the slant was 45 degrees. I set the miter to 45, place the crown on the miter saw fence (top of crown pointing vs the traditional pointing down setup), cut the miter, and it all fit.
Thanks again for your help.
Well then if you'd be so kind.............
Post a picture of it.
thanks.
