Synopsis: Add this to any table saw fence to make micro-adjustments easily. Adjust your rip fence with precisionI DEPEND ON MY TABLE SAW for a lot of precise work, and I’ve become an expert at the “fist-bump” method of rip fence adjustment. So when I was asked to look at the T-Fence MicroMag Adjuster from Canyon Fire Tools, I was skeptical. With the rip fence unlocked, I was able to adjust it precisely with a slight spin of the thumbwheel. The magnet connecting the adjuster to the guide rail (sold separately) is switchable, which allows for big fence adjustments without having to remove the MicroMag from the fence.
