If your shop is a bit short on clamps, here’s a way to mount small to medium-sized featherboards with one clamp instead of two. I wrap two rubber bands around my featherboards, which gives them much better “grip” against fence facings. Space the rubber bands apart and place the clamp between them. Tighten the clamp and your featherboard will stay put. For long featherboards, I stick with two clamps.
