Okay, I'm stumped. How would you suggest I make the joints on the clock case shown in the attached sketch. I don't know if just a straight glue joint will be strong enough. The 90 degree corners aer suited to making finger joints, but what do you do with the obtuse angle joints at the top corners? How do you cut finger joints on an angle. these pieces are 3" wide and 3/8" thick.
I also thought about:
1. A glue block cut to fit inside the corners.
2. Using screws from the outside.
Am I missing an easy, but strong method here?
