Scrub Brush Featherboards
I saw this featherboard idea on a routing tool called the WoodRat. I liked it so much I adapted it to my router table. The WoodRat uses a single wooden scrub brush glued to a board. I wasn’t able to find wooden scrub brushes so I bought a pair of plastic ones. I simply screwed them to a mounting board, one for infeed and one for outfeed. They do a great job of holding the workpiece snug against the fence during routing.
