Best edge finder?

[TomG]

I used a 1/2" dowel pin as my "edge finder" for years. With a work light behind it, it was very easy to see when the rotating pin touched the side of the work. It worked every bit as good as the spring loaded edge finders but wasn't nearly as cool.

And while we are on the subject of edge finders, let's not forget the ultimate edge finder, the chair type.



You just stick them on the side of a steel workpiece (they are magnetic) or hold or clamp them against the side of a non-ferrous workpiece and indicate the slot or hole. Not nearly as handy as the others, but ultra precise. Moore makes one for use in their jig grinders (at over $4K on the Moore website, it's WAY too pricey for me, although I believe Bill Gruby has one). I have to settle for the knock off SPI version.
