You don't say how thick they are? I personally think a router is overkill. Clamp a few together, clamp the job to a steady surface. Put a good quality new blade in a jig saw and use fence clamped to the work. Then take your time, don't try and rush the blade and it will give you a nice neat cut. :wink: It's tempting when you have a lot the same to do to try and find a quick way. Don't do that, it doesn't work out.
