Angled and center keyed box joints
New to woodworking. General questions concerning angled and center-keyed box joints. All videos and written instructions concern 90 degree box joints. I am interested in using box joints to join the sides of a triangle "box". Is the answer to 1) cut each board at the appropriate angle then 2) use an angled jig to cut the pins ? Also, is a center-keyed joint out of the question with an a angled box joint approach? - seeing as the videos I have found concerning center-keyed box joints require the piece be flipped. Flipping may be problematic given the angle. My goal is to use box joints with a triangular box.....ideally with a center key for each of the three corners. THANKS
