Today I've been working on rustic book projects, two variations of a coffee table design made from consecutively sawn spalted maple slabs. One variation has a base made from tree limbs using the Lee Valley-Veritas tenoner as shown in the first photo. The tops for both versions are textured on the edges using a rotary chisel as shown in the photo below. The patented rotary chisel is a lot like a router bit, but is intended for use in an air powered die grinder. I use a roto-zip as the source of power so I don't have the compressor noise to suddenly distract me. You use it like a tack hammer. A light tapping motion against the wood creates a random carved texture. It helps to pay attention to the wood grain and direction of rotation to get the smoothest cut.
