Hi Brian and welcome to the forum. I've made a few frames mostly because the ones my wife liked were too expensive to buy($25/ft of molding). Looking at them I realized that most were made from a variety of common curves and could be made in numerous passes with router bits. It will be helpful to mount your router horizontally or overhead, possibly on skis.Both can be researched on this forum. The problem with trying to make frames on a router table is that you cut away the wood that the piece needs to sit on for stability. You can do some by leaving 1/8" on either side untouched and then rip those parts off later on a saw but the other mounts will offer more opportunities.
Someone I consider a master woodworker once told me that a master woodworker is not someone who never makes mistakes. He is someone who is able to cover them up so that no one can tell.
