I'm terrible with the chisel and wondering whether a router can be used
to make mortise cuts for hinges. I imagine that you would need to have
curved corners in the cuts. Is that so? In that case, do there exist 1
1/2" hinges with curved corners?

As many have stated, it's pretty easy to square rounded corners with a flat
chisel, but if you're 90° challenged, you can use a chisel similar to what
Norm uses to cut corners for hinges. Norm's is spring loaded, this one is
magnetic.
