Richard,

I cut the board out with a router running along the spine, tail and bent 
side. I don't cut along the belly rail, It can be pried off easily. The 
cut is a constant dimension from the rim having been indexed with the 
round base of the router. I can measure from the edge with a simple tool 
to draw a line on the new board in order to cut it out to the right size 
to fit the case.

I am not sure were I got this idea but it has been around a while. 
Willis Snyder probable invented it.
