Step 1: Materials and Tools
I often see these older style bed frames dumped on the curb when people move, this one came from across the street. Otherwise you can find them for pretty cheap at Goodwill or at yard sales. Bunk beds are a good source material because they are solidly made, have many matching pieces, and often have six side rails. You could also use two similar twin frames with additional scrap wood.
-2 matching or compatible headboards (front and back of the workbench frame)
-4-6 side rails or plywood/MDF sheet (benchtop)
-Bed slats, headboards, footboards, or other scrap wood (frame supports and bottom shelf)
Wood screws and nails- Many screws can be re-used from the original frame, but more will be needed.
Electric hand drill
Pliers- Great for removing wire nails
Hand saw- Minimal sawing required
