Adding to bench top thickness for Roubo Workbench
I intend to build a Roubo style workbench with leg vise. I already have a maple slab for the top which is 2 inches thick, 3ft. x 6 ft. that I got for free. Most plans for Roubo benches that I’ve seen feature a top thicker than 2 in., usually at least 4 in. My questions are: 1) Should I increase the thickness of the top? 2) If so, how? Could I had several layers of birch plywood or MDF underneath? What other material would suffice? I would probably put an apron along the front and back edges that would cover up the mismatched materials, and end caps would cover the ends. Thanks.
