It's pretty much what looks good to you. If you mark it out as I suggested then with your chisel bevel down you start at the corner and make one sweeping arc cut towards the half inch stop cut blending into the chamfer. Normally this arc is a 45° sweep. In learning the technique start with making a couple of these arcing cuts first.

I can drawing up more technical details if it benefits anyone. Just let me know. 

Yes there are definitely some  improvements required in Craftisian's navigation. But who's listening that will make required changes?

Hey Lazyman.... you can always follow me if you want.
