I few weeks ago, I wanted to do a little project or two, so I made two try squares, and two marking gauges (one a panel gauge). The design for the gauges came from the classic Charles Hayward "How To Make Woodwork Tools", and the squares from a Jim Tolpin article in Popular Woodworking, "Building a Handmade Try Square".
The squares are made from some nice elm a fellow woodworker gave me, and some walnut I had in the shop. The gauges are white oak. These were fun, and I definitely have the bug for making my own tools. I'm sure there's more to come.
