crown molding cuts, geometrically impossible ??


installing 5 1/4.
dealing with 2 levels of celings.

ist it mathematically impossible to join a horizontal piece of crown to a vertical piece. and then back to horizontal.

This is the spot where i need to transfer from one ceiling, then up the wall, then to the next level ceiling.

Been slamming my head against the wall trying to cut samples and figure this out.

Im working with a 12" mitre saw that the blade only tilts 45 to the left.
Guessing i might need a dual 45 tilting saw.

thanks inadvance.

Chris

I've never tried this before but it seems like you could turn the crown "right-side up" in the saw (opposite the correct way) & cut it like a usual o/s corner?
Let me know if this works.

Thanks for the repsonses. I have spent 3 hours of web surfing and could not find any info on how to do this. Or any pictures showing it being done.
I had to finish the job and ended my ceiling levels with return mitres and butting against walls. Still turned out nice. Used knotty alder with glazing to highlight the profile.

"Crabby Bastard", please post the name of that book. I want to figure this out for future work.

Thanks Again.

That'll work! Post some pics, please.

I've been know to do "the impossible" using power tools "the wrong way." Against my better judgement, but then again I have none. Then I see contractors and tv show people using "my techniques." As long as you know what you are doing (or at least THINK you do), and end up avoiding body parts getting eaten you're golden. Make sure you have someone there who can dial for an ambulance or apply large amounts of super glue. (EMT joke - yes I have training for that too.)

We Jeepers seem to do things our own way; making up ways to get our butts outta trouble!

i didn't get a chance to look for the book last night, will get it tonight. i can tell you it came packaged with a product called ' the original angle finder" or something like that. i'll see if i can find it on the web.

it was bought for me as a gag gift when a buddy came to my shop and saw that my office has vinyl cove base instead of wood moulding ( that's the way the space came). he likes to say it's like the chef that orders pizza for his family. it's a handy book, i'll see if i can find it for you
