Thanks, fellas, and Sam, that's a pretty slick idea and will have to seriously consider it but I'm thinking I may incorporate spacers at the headstock/router mount instead if need be. The router mount will have some flexability/adjustability as I'd like to be able to do guitar bodies as well as other things so they'll definitely be some "figuring" in the Z travel height area for sure.
I'll be working from the ground up so I need to come up with a sturdy bench to mount it on. Was thinking about one these roll away toolchests but they can get pretty costly for the larger/sturdier models.
We'll see....
