Milling the dowel jig I always wanted

Milling a metal block in to a dowel jig for 3/8-inch dowels. Essentially a 3/8-inch drill guide with four holes, to be screwed to a block of wood which is then clamped to the workpiece. This will simplify some of the dowel joinery I often make. This is my first project using my homemade milling machine contraption. Far from perfect, but much better than trying to do this with a drill press.
