BLADE-HEIGHT GAUGE BLOCK
Here’s a quick way to set the height of a table saw blade. I cut notches on the end of a 4x4 block at the blade heights I use most often: 1/4 in., 3/8 in., 1/2 in. and 3/4 in. To use the block, position the desired notch over the blade and raise the blade until its highest point just touches the block.
