A small coffee shop and wine lounge here in our small town had asked me to build them a long coffee table and pallet wood cabinet last year and they recently contacted me and asked me to make them several pallet wood benches.
I built three at 35"x16"x18" high and one at 70"x16"x18" high. They asked for a back and sides on the long one. I did use store bought 2x4s for the frames and up-cycled wood for the legs. I distressed the 2x4s before staining so they would match my pallet deck boards.
The legs are cut and planed from some long stacker boards that my son is able to get from his stainless steel tank factory.
I used my Kreg jig to build my frames with pocket hole screws so they wouldn't be visible after construction.
I then used two 1/2" wood screws and wood glue to attach the legs to the frames.
After cutting my pallets apart I used my table saw and miter saw to square off and cut down all of my deck boards.
I then attached them using wood glue and trim nails. The back for the long bench is a piece of "scrap" cherry MDF I was able to bring home from the cabinet factory where I am employed.
After sanding with my orbital sander the legs were stained ebony while the frames and deck boards were stained early American and then everything was finished with two coats of satin polyurethane.
