New bench leg vise detail

The leg vise is attached to the left front leg of the new bench. The vise chop is 8/4 sugar maple (Acer saccharum). I turned the screw and hub out of a piece of 5x5 inch apple wood (Malus domestica). The vise handle is oak (Quercus spp.), pinned with black walnut (Juglans nigra). The parallel guide and screw protector are black walnut.
