Last week we had my son's Cub Scout den over to build their pinewood derby cars. It gave the kick in the pants I needed to build three of these benches. I had originally bought the vises on clearance for $9 each, I would use a larger vice with a dog if I were to build more. Inspiration was by way of Fine Woodworking, but I didn't use maple everything.
The benches stand at 30" with a 14" wide by 36" long worktop. The vises can grip material up to 4". The plywood is 3/4" and 1/2" scrap radiata pine (doubled up for the worktop), scrap 1/2" baltic birch plywood for the vise faces and new kiln dried studs for the legs. Glue, deck screws and assorted nuts and bolts. I think I'll give them a final sanding and seal them up because I'm sure they'll be left out at times.
