I'm assuming that both sides will show so you can't put a hole where it

the piece with paper inbetween; make your hole in it, rout, knock off the
wooden tab, scrape off paper.

And, add shims, of the same thickness as the "wooden tab", to the bottom
of the router end of the trammel to keep the trammel parallel to the
workpiece, otherwise the edge of the routed arc will not be
perpendicular to the face.

Now, that's where that double sided tape will come in handy.
