Installing a router table in my tablesaw’s extension table saved a huge amount of shop space, but I needed to turn the rip fence into a router-table fence, and figure out how to collect dust. I solved the problem with an auxiliary fence that is simple to build, fast to put on and take off, and gives a neat way to collect dust at the source.

The fence is basically a hollow box made from 3/4-in.-thick plywood that attaches to the tablesaw fence with two universal fence clamps (Rockler.com; No. 31373). I used slippery high-density polyethylene (HDPE) for the fence faces and bottom, but melamine or plywood would work, too.

The faces are mounted on T-tracks so they can be slid back and forth to create an opening for different-size bits. They can also slide together to create a zero-clearance effect, if desired. The T-track above the fence faces is for hold-downs and stops.

I drilled a hole in one end of the fence to match my shop-vacuum hose, which draws air through the opening in the fence and almost eliminates dust. The entire setup works great.

Woodriver Circle Cutting Jig

The WoodRiver circle jig, which produces cuts up to 32-1/2 in. dia., and I can confidently recommend it. Unlike similar jigs that can pop off of their pivots mid-cut, ruining a panel in the process, this one has a robust pivot point that registers securely in the jig and workpiece.
