Crown Molding Copping both ends
I have three walls done in a room that is about 18' by 11'10".
The walls under 12' work nicely with a 12' length of crown molding, yes obvious. Anyway, I install one unbroken turn on the 12' wall opposite the entry door and made the two ends of this run Butt joints to walls. Thus, it was easy to fine-tune the length to fit nicely - small gap at each end. I then copped a joint for each of the two side walls (18') making a scarf joint and ending in a butt join against the remaining wall. Best or not this is what I have done.
Now, I think it would be nice to take another 12' and cope the ends of it to meet the two butt joins coming from the side walls. But! I do not believe I am that good a cope so I think the best thing I can do is buy a 12' length of molding (this is the 38 degree and small crown molding - room has 8' ceiling) and cut a scarf joint about midway. Then I can cut independently each of the cope joints and fine tune the length at the easier scarf joint. I have an accurate power miter saw and can cut small adjustments in the length at the scarf joint.
This will leave me with one scarf joint on this run, as I also have on the 18' run. I am confident I can make it fit this way, not sure I can if I try to adjust at the cope joint.
Any views, does the plan sound Ok, even good/normal?
