Thrifty Router Bit Bumpers

Router bit bumpers with dried silicone obviously works for the bottoming out problem with router bits. An easier solution with no mess or fuss is to simply roll a small “O” ring onto the shaft. O rings from old water shut-off valves work great for 1/4″ shafts. Half inch shafts need a larger ring but they are not hard to collect. I save mine from water filters from my KitchenAid® refrigerator.
