This was my first built-from-scratch workbench that I built for our house in April of 2017.
I made it out of 2x6 and 2x4 pine lumber, The top was built by gluing up 2x6 boards and planing and sanding the surface flat. The legs were made from laminated 2x6 boards with wheels on the bottom so I could move it around as needed (although I don't think I ever moved it). I made the bottom shelf with 2x4s and used the cut off edges of other boards as the top. I bought 2 extra drawers from the cabinets I bought (seen in the third photo) to mount up under the workbench for storage.
This bench is still in use on the back wall in my current workshop today.
