   Groovy vs. wavey-gravy

   Consider using a guide bushing in the router base, along with a template that has both exterior and interior sections - essentially guiding both sides of the guide bushing, keeping the bit on the straight and narrow, so to speak.

   The wrinkle here is that the bit needs to center perfectly inside the guide bushing, or you'll get variations as you move the router through the template. The guide bushing inset on many stock router bases can be a bit sloppy, and guide bushings can also be less than precise. I use a "Precision Base" from Pat Warner to solve that problem.

   I think I might use an edge guide. Not sure if you have one though. The guide bushing is also a good idea if you want to make the template. You might have to make it pretty thick so your bushing is activated before your bit hits the surface (I'm assuming you are using some sort of plungable cove type bit). Whatever you decide I would give it a go on a piece of scrap and figure out what you are comfortable doing.
