I am wondering about installing toe or shoe molding using contact cement. It would eliminate nail holes and (I think) could be removed with some effort. Also it would adhere to the factory finish on the hardwood floor. I however, don't have a lot of experience with contact cement, and would appreciate some advice. My other idea was to use hot glue, but it would be challenging to get the pieces in place without the glue cooling too much. Any other suggestions appreciated! (ignore part about sticking it to the floor... forgot about expansion and contraction of hardwood)

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. [attach]113602[/attach] 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: [attach]113601[/attach] 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. [attach]113603[/attach] I looked at pendants in CADD; They look ridiculous, so I'm not going that route. I found that a smaller-dimension identical-profile crown [i]sorta [/i]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. [attach]113604[/attach] That's my dilemma. Any experienced trim carpenters have some suggestions for me to consider?
