So, you want to make sure your table saw is accurately set, but not sure how to test it? Here’s a method that will give you a great way to check just how squarely you have set your rip fence to the blade.
Basically, this method relies on producing a cumulative error on the cuts that magnifies just how far off the fence is. This makes it considerably easier to measure how much you have to adjust the rip fence in order to bring the alignment into square to give you more accurate cuts.
Once you use this method, you’ll find it to be pretty clever, and you’ll use it frequently to make sure your saw has held its setting.
