NOTAHD, is your bike a Classic or Meanie rather than a Nad? The Gadget article shows the innards of a Nad goat belly which must be a little different with one pipe coming out for the left side. I'd like to hear from someone who's done a Classic or Meanie belly and whether it should be cut the same as Gadget shows for the Nad, e.g. horizontally along the seam until nearing the in/out pipes, then across the bottom to meet the horizontal slice (leaving the end section with all 4 pipes intact)? Or did you just rip it right up the seam the full length?
