@theknightlynews You need the transition piece so the profile of the crown will match up when you go around the corner. Without it the angle makes it impossible to make it match up.
Thank you for this. I was able to put crown molding up in the new baby's room in one afternoon. Corners came out darn good and the wife thinks I'm a champ!
Expansion and compression will always happen in a home. A true craftsman will always use the coping method for an inside corner unless the angle was too shallow. This method is best if time was an issue and you had to rush through it to get it done or if you were doing it for your mother-in-law's place.
dude a real carpenter know jigs that are used for holding store bought are looking for a simple fix when all you need is experince and a contractors license then you would be doing stair systems design and build and have kid do this by cutting flat compounded
