I cut my patterns with a saber-saw, freehand, except for straight lines, where I use a fence and circular saw. Just cut a little proud of the finish line, and sand to the exact line. If you are using the router to cut sides from a pattern, make sure to fill any voids in the pattern ply. You can cut a dimple into the finished product if you hit a bump of void in the pattern...Don't ask...

Once cured, gorilla glue is easily scraped from areas where you don't want it. I use blue masking tape to keep it off finished surfaces.
