Change Router-Bit Bearings Without Getting Cut
Removing a bearing from a router bit can be awkward and hazardous to your fingers. But this little device makes the job safe and easy.
To make it, you need only a stick of hardwood and a few lengths of 1/4-in.-dia. dowels. Drill holes for the bit shanks, then add holes for the dowels. In my jig, the dowels are spaced so they work for many sizes of router bits, from a 31/2-in. panel-raising bit to a tiny 1/4-in.-shank laminate flush-trimming bit. The dowels keep the bit in place, so I can remove the bearing without holding the bit in my hands. Don’t glue the dowels; you’ll need to remove some of them to accommodate the larger bits.
