I'm hanging crown moulding (typical profile) along a convoluted contiguous line in a high foyer. The runs and miters vary, and the height and interferences make the project a challenge. But one spot in particular has the project at full stop. Take a look at the image below: The blue line indicates the line that has stumped me.
The slope of the ceiling is 30°. The crown follows this slope, then must turn 90° (forming an outside corner) for a horizontal run, then turn another 90° (forming an inside corner) to resume the 30° slope. My problem is, I cannot figure out how to transition the crown at these two corners.
I've modeled the area in CADD to help me evaluate options with actual geometry:
The image below illustrates the problem. The trim shown in the image are identical. You can really see how the ceiling slope creates a transition problem at the corners.
I looked at pendants in CADD; They look ridiculous, so I am not
going that route.
I found that a smaller-dimension identical-profile crown sorta works at the corners. The transitions aren't perfect, but close enough given the height. I'm more concerned that the smaller trim used for the horizontal run will look disproportionate.
That's my dilemma. I've checked out whitepapers about trim compromises by both Gary Stiegler and Gary Katz, but to no avail.
Any experienced trim carpenters have some suggestions for me to consider?
