Tool Pr0n: Planing Form Depth Gauge

4Dorks on Flickr posted this awesome (strobist) shot of his custom-built depth gauge, which he uses in conjunction with some of his other custom tools to build split-cane bamboo fly rods. For those of you who build fly rods, this tool helps set the v-gap in the planing forms.
