Interesting ideas here! If I were going to rout a radius on laminated linings, Pete's method looks good. Not routing is certainly a valid choice aesthetically. Also, while it is true that rounding over the edge of the linings doesn't remove a whole lot of material, leaving that material in place works toward the goal of maximizing mass in the laminated sides and linings. Not by much, of course, but we're chasing down little bits of improvement.
