Arran, the problem with using an ordinary router (or Dremel router) with a pattern on the top side would be the curly-que near the bottom. With the over arm router, there is a guide pin located directly under the router bit that follows a pattern on the underside of the work piece.

The pattern used to cut the vein and the grille.
