Make a Simple Shim-Measuring Gauge

If you need a custom shim that you have to cut to a very specific dimension, you could try to use a tape measure to measure the gap, but there's a better way.

Justin Fink of Glastonbury, Conn., discovered this method for making a simple measuring jig. What it is is a wedge of wood with about a 5-degree bevel, and on it are thicknesses marked out in 1/16-in. increments--1/16, 1/8, 3/16, 1/4, and so forth. He's added some shading to every other space to make it easier to read. And here's how it works.

Simply slide it into the space that you are going to measure--in this case I'm measuring between a door jamb and the framed rough opening, and the shim clearly needs to be 5/16-in. thick.

It's a pretty clever tip, Justin. Thanks for sending that in.
