6ft Roubo 18th Century Workbench - the next one will have a cherry top and white oak legs and stretchers…and will be 10ft long. 

I make these workbenches from the ground up including a wood vise screw and nut for the leg vise. The top is attached to the base via double tenons - one of which is dovetailed. Options for workbench lumber includes douglas fir, yellow pine, white oak and sometimes other woods if they are available at the time of construction. The bench in pine starts around $2000.
