I would suggest using straight cuts to approximate what you want ( make it
a bit larger than you need ), and then bond the diagonal to the face of a
diagonal cut block ( a chunk of wood 5" round and cut diagonally would
be perfect ).

Coat the surface in wax to protect it, and then grind the edges to suit on
a fine wheel.

The big danger here is, of course, cracking. Go slow on the grind.
