The fence of a router table prevents you from running a bead on an inside curve. I did some research online and found one guy that tapped his router base, added a pin (a bolt), and ran it hand held. Yikes!
So I came up with a way to do this much more safely by clamping my router lift and router vertically in my bench vise in portrait position (narrow dimension is left to right). Then I tapped an electrical nail strap for a bolt that became the “pin” that I ran my piece against. I then added a fence. It worked remarkably well. Watch a video here.
