I found this online, but the link to a tool seller didn't show them. Was this it?
those work premium...I forgot to mention Board Buddies for the router table: https://www.amazon.ca/Woodstock-W11...=2025&creative=165953&creativeASIN=B0000223VK That's one other option.
will that brush hold against a kick back???The WoodRat uses a stiff bristle scrub brush as a featherboard. I've tried using a brush like this as a featherboard on my router table, and it works quite well. I attached one to a board so I can clamp the board to hold the brush in just the right position. It works quite well.
