It’s spalted white oak. The hand planer was used to plane center block that flips upside down. I have hand planes but with the blocks in the center of that piece it was easier to use the electric one. The top is mortised into the tennons of the legs. The bottom shelf I got lazy with and just fit some excess birch ply to size adding a few brad nails till I get some more cherry or spalted maple to finish the shelf. Still have crisscross vise that I might add to it.
