To cut smooth circles, you need a jig of some kind. While a shopmade router jig will do the trick for an occasional tabletop or two, it’s nice to have a manufactured jig that is quick and easy to set up.

I recently tried out the new 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.

A guide bushing (included with the jig) goes in your plunge router and engages with a bearing in the jig, letting the router pivot as it travels. The bushing guide lets you plunge the bit and make the cut with multiple passes for the smoothest possible results. When your circle or arc is cut, you simply lift the router away and store it instead of having to unscrew it from a shopmade base.
