The most important thing to do for your table saw fence is to always calibrate it. Of course, you have to do the blade inspection and cleaning. If you have your blade correctly aligned, you will get clean and accurate cuts. Adjusting the fence is merely placing it precisely into the miter slot. There are several ways that you can do to align the fence to the miter slot.
Before starting to align the fence, check the position of the miter slot and the blade. Make sure that these two are parallel and perfectly aligned. The calibration of the miter slot and the saw blade is not something that you can do frequently. What you need to check regularly is the alignment of the fence. It is because the fence can easily lose its precise alignment due to daily saw usage.
Fence Aligning Check
Before aligning your fence, it is better to make sure that the saw blade has been unplugged from the fence. For the easiest and simplest method, you can measure the fence alignment by using your finger. The finger is functioned as a gauge which can sense along the fence and the miter slot.
Place your finger on the miter slot sidewall nearest the fence. Move the fence until its face is in parallel with the miter slot side. Then, move your finger along the miter slot the saw’s back edge. See if the miter slot and the fence are even at their ends. If both are uneven, you have to do fence alignment.
It seems that the fence is somewhat toed in. It means that the fence back side is closer to the saw blade rather than its front end. You can position the fence back to its normal place by adjusting some screws. Each fence is being designed slightly different and you have to adjust some set screws. These two set screws generally move the fence in and out. The movements of the set screws influence the position of the fence whether it becomes further away or closer to the saw blade.
After adjusting your fence, you can check the result with the dial indicator if you think that your simple method is not really convincing. You can use this dial indicator to measure the miter slot and fence distance. You have to measure the distance of the front and the back of the saw. If the distance is not more than 15 one-thousand inches, it doesn’t matter.
