Easy multitasking height gauge

After trying numerous store-bought blade- and bit-height gauges, I came up with my own simple version that works great for multiple tools: tablesaw, router table, plunge router, etc.The hardwood base holds an upright that's grooved vertically to mate with a sliding dovetail. Size the dovetail on the sliding gauge so that it slides freely. Attach a self-adhesive rule to the face of the dovetail. Then drill a 3⁄16" hole, 3⁄4" deep in one side of the dovetail to fit a ballpoint-pen spring and a small dowel. This gives the gauge a friction fit to hold it at a set height.—Junior Strasil, Falls City, Neb.
