In past issues of Wood, you've listed the correct speed range to use for router bits of various diameters. This guide gave me an idea.


On the top edge of my router bit drawer, I drew hash marks corresponding to various bit diameters. Between these marks, I wrote the appropriate bit speed from your guide. Now, when I pick up the bit I want, I simply hold it against this guide to determine the correct router speed.
