Hi all, here's an edit to a question about inside corners on Carpentry and Woodworking:
EDIT: I was suffering extreme frustration with my first crown attempt today. I just realized that I was cutting OUTSIDE miters for my INSIDE corner copes. I mean, hey, the outside cuts slant back to overlap the moulding it's fitting to, right? In appearance yeah, but the curves of the moulding won't be accurately angled/displayed for back-cutting. No wonder my back-cut curves wouldn't fit.
So, I will try INSIDE miters for my INSIDE copes' back-cutting. I bet they will match up just fine now. I hope someone learns from my goof. I'll post results.
I am happy to report that I made the proper cuts today (inside miters) before my coping back cuts and presto! the rest of the crown job was banged out in a couple hours. Amazing. I am feeling a deep sense of pride on how well it came out. Thank goodness it's primed MDF and not natural hardwoood, lol! A little caulk and paint does wonders. Seriously, though, I am very happy how it came out. I will put up a new post with before and after pics of the kitchen when the lights are in, etc..
BTW, I just used a coping saw and half-round file for the back-cut. I found that a single edge razor blade really does a nice job of cleaning up the back, too. I actually got pretty fast after my second one (total of 5). My scarf came out super clean, too.
