Seems like I’m always looking for my tape measure to set the height of my table saw blade. This simple jig, made of scrap plywood, makes that annoying search unnecessary. It wraps over my rip fence and has a length of paper ruler that I printed out for free online glued to its face. The jig’s facing and ruler touch the saw table. To set blade height, I just slide the jig and rip fence next to the blade so the ruler, aligns with the highest point of the blade’s arc.
When I’m ready for cutting, I flip the jig around and store it on my fence where it’s safely out of the way but still ready for my next cutting need.
