I made a router jig very similar to the one Richard McLean describes in FWW October 2000 #144 that my high school kids use for gooseneck moldings with very good success. The only thing I changed from McLean's was that I made rollers on the ends of the rub blocks that attach to the wood outriggers. The advantage of having two followers touching at the same time compared to Glen Hewey's one, I feel, is that you can really maintain a close profile (even a H.S. kid!) The rollers, made of plastic or hardwood, reduce friction and you just zip along in progressive steps to rough out the bulk of the material. Clean-up with a few gouges and scrapers and you have very little to sand- KIDS DON'T LIKE TO SAND!
One thing you have to be careful of though, with two followers you must have very close tolerences to the total width of the molding. We draw the top edge and transfer the total width of the molding with a compass scribing a series of arcs and French curving them in. Your first dry run with the router set up high will tell you if there are any tight spots that need to be addressed before routing.
