One door as a makeshift workbench is so pass, try using a bifold door.
Here’s How to Make It
Old doors laid across sawhorses make great temporary workbenches, but they take up a lot of space when youre not using them. Instead of full-size doors, I use bifold doors with hinges so I can fold them up when Im done working. Theyre also easier to haul around in the pickup for on-the-road jobs. Harry Steele
