I have a more general question (or questions), just out of curiosity:
I assume that the weight-relief "channels", as well as the larger semi-hollow cavities, are routed out from the top side of the main body wood, prior to the top piece being glued on. (I don't see any other way to do it, basically.) Presumably at least the top surface of the main body has already been planed. I would also assume that the locating holes would have to already exist on the body, so that the CNC machine knows where to route. Then after the top is glued on, then you can do top-side carving/routing (both of the top carve, as well as the pup cavities, holes for the pots and switches, etc.), as well as the bottom-side carving/routing (for the trem cavity, controls cavity, etc.). Is this the basic sequence?
With my CU24, it doesn't seem like any routing needs to be done before the body and top are glued together. In other words, I think everything can be routed from the top or bottom of the body/top sandwich, after the maple has been glued to the mahogany. Is this true for all of the double-cut guitars, or everything that isn't weight relieved or semi-hollow? I suppose that the wiring channel on the SC guitars from the pup switch to the control cavity might still need to be pre-routed before gluing the top wood onto the body...
The virtual tour of the PRS factory, in the section that talks about body construction, seems to just show the double-cut process, where it doesn't appear as if any routing is needed before the top wood is glued to the bottom wood. But I hadn't really thought about the fact that it's more complicated for any guitars with weight-relief or semi-hollow bodies, and that even a "solid" SC guitar still has to have the wiring channel to the switch routed out.
Or am I misunderstanding how my CU24 was built, and there is in fact some amount of body routing that had to be done before the top was glued on, even for this non-weight-relieved DC guitar? You still have to create a wire-channel from the pick-up cavities (routed from the top) to the control cavity (routed from the bottom) - is this done via a horizontal (or mostly horizontal) drilling step? Or were these channels actually routed before the top was glued down?
Obviously there is no real need for me to understand this - I just find it interesting!
