Not giving up yet, but help needed.

This is a crown molding problem. I might be just missing something, so hopefully someone can help me figure it out. Picture this if you can.
I have a wall with a fireplace centered between the two outside corners. I then have a 3/4" MDF facing than runs floor to ceiling and 7/8" in from each outside corner. The outside corners of the wall are bullnosed, corner of the MDF is square. I then have a light box that holds the fish eye can lights that is set back another 7/8" from the outside corner of the MDF facing. My crown is 5 1/4". I have run around the box and around the corner of the MDF (3/4") to the wall. I then only have 7/8" before I need to start making my bullnose corner. Does this make sense? [blink]

Please help!!!!!!!!

Glad you posted a pic.  I looks like your question is how to turn the corner on the bullnose?  If so, here are some thoughts.

First, it looks like the bullnose extends past the flat plane(s) of the walls.  If so, I would cut and remove the bullnose at and above the bottom line of the crown.  Then measure and install the crown so that the miter meets at the intersection of the two wall planes.  There will be a small hole or gap under the installed crown, but I believe that a bit of filler (or caulk)will work, especially with the textured walls.

If this were stain grade work, on smooth walls, I would still cut the protruding bullnose, but consider easing the corner by installing two 45 degree miters (22 1/2 d cuts) .

Or, you can still cut the miter at 45 degrees, then fill the hole with material that matches the crown.

Hope this helps...  Dan

To my eye, crown looks better with a single 90 degree corner rather than 2 45 degree corners.

Probably not even worth 1/2 cent  [tongue]

Thanks Dan,
I hadn't considered using two bullnose crown pieces, that might help alleviate trying to match back to the 45d  inside corner already installed.

Or I might be working in the wrong direction. remove the outside corner already installed around the edge of the MDF. That might be the piece that needs to be cut down to make room for the bullnosed crown.

here is what the 22 1/2's look like

Scott,

I'm not sure what you mean.

Or I might be working in the wrong direction. remove the outside corner already installed around the edge of the MDF. That might be the piece that needs to be cut down to make room for the bullnosed crown.

  The existing inside corner should be ok.  It seems to me that the exposed outside corner is the problem. 

Maybe I'm missing a definition:  Can you explain what you mean by "bullnosed crown" ?

Sorry Dan,
      running the crown around the bullnosed corner. I normally use 1 piece to make the outside corner of the crown on the bullnose, usually 5/8" at the bottom of the crown (heel to heel). Although I have used 2 pieces to make the outside corner. My ultimate problem is that the 1 piece bullnose outside corner hits the inside corner of the already installed crown.

 

[danrush]

Scott, I'm a confused guy!!  Can you show a pic of the proposed piece, and the problem?  Just hold it up with your hand and shoot a pic. 

Sorry, I'm probably the only guy not seeing the problem

Dan

But Dan you are right, the existing installed outside 90d is the problem. That's why I was saying remove that outside corner (2 pcs) and work from the bullnose corner. This might not solve anything.

I will shoot a pic of it in the morning (Saturday) and post, heading to the wife's office Christmas party. (Oh boy)!!!!!!

You will not be able to do it how you want with what you have there in your picture.

What is the 3/4"x 3/4" piece of mdf for?

 

[mastercabman]

I would cut the mdf right below the crown.and do a regular inside corner.It looks too busy with all those outside corners.
I would do a double 45* around the rounded corner bead.

The MDF is part of the facing of the wall. Runs floor to ceiling and corner to corner - 1 3/4". There is a light box that runs corner to corner. The crown coming from the right of the pic is running on the side of the box. The box is set back another 3/4" from the MDF corner. The wall was originally designed to have just drywall with a mantel and leg setup around the fireplace. MDF facing with applied picture framing on that wall was an added design.
