This is a micro-adjuster jig for use with my SawStop JobSite table saw, which has a problem where the fence doesn't stay in the same position when you unlock it, so it's hard to sneak up on a cut. So I use this jig to help fine-tune my fence's location. It's not perfect, but it works. #TNW V1.00. You can hide the version number, but don't delete it.
