How do you make ultra-fine adjustments to your table saw fence position? Here's a common method: First, hunch over your saw and train one eye on the fence's positioning cursor (if you are fine-tuning the fence position based on a test cut you've made, remember to take note of the exact position of the cursor when you begin). Watch the cursor's movement closely as you make precision position adjustments by alternating tapping on the left and right side of the fence with the heel of your hand. When you get close, switch over to using your knuckles (most woodworkers agree that knuckles are far more accurate for adjustments of 1/64" or less). With this method you'll find that, as your skill increases, and with a little luck, you'll be able to make reasonably accurate fence position adjustments on your table saw a good percentage of the time.
An alternative method - and the one we recommend - is to buy the Rockler Table Saw Magnet Micro Adjuster. It's affordable, attaches to your table saw in seconds (without tools), and makes accurate fence adjustments to .001" and less quick and easy - every time. No alterations to your existing table saw set-up are necessary - the tool attaches to your saw's front rail with powerful rare earth magnets, so you can move it and re-move it as often as you need to position a wide range of fence settings. If you need to do cutting that requires extreme accuracy at set up time and you want a fence positioning solution that's hassle free, doesn't cost an arm and a leg, and really works, you won't do better this precision fence positioning tool.
