When I built the router table onto the tablesaw I thought why reinvent the wheel, so for a fence I built one the slipped over the tablesaw fence and I clamped it in place
I very soon discovered the folly in that. As soon as you get a set-up on the tablesaw, you have to move the fence to route something and vice-versa.
I couldn't justify buying another biesmeyer fence, so I thought I'd try to build one.
I seems very stable and firm, we'll see how it bears up with use.
