This is an extremely solid, continental-style workbench I built with and for my kids - but since it's the best workbench I currently have, it's become my favorite, as well. I will be posting the adult version, later, when I have finished it. Materials are spruce and MDF; bench screws are from Busy Bee Tools - SketchUp model for these is available separately in the 3D Warehouse. The spiral-threaded hex bolts used to secure the legs I created using my 'bolt creation toolkit' model. Finally, I cheated on the shoulder vise. It's secured to the bench using two 8" heavy duty drawer slides. Still, this gives you two ways to use this vise - as a proper shoulder vise, or as a full-length tail vise.
