No idea on an extra length bit, but maybe we can help figure out why you are having problems? Which sign making kit do you have? Which router are you using? Can you describe the main problem that is stopping you? Is it play in the frame? How deep are you trying to cut? What type of guide bushings? (Plastic/steel/ brass?)
I had problems at first with my sign making jig but worked it out. Hopefully we can get you going.
