Porch Swing
I had a few old 2x3s and one 2x4, so I sliced the 2x3s into slats, glued up and laminated some cut pieces to make the bigger stuff I needed and made a porch swing for my wife. I had to buy carriage bolts, eye bolts, and quick links, but everything else was just stuff that was stacked in my workshop. The hanging frame was from an old metal and canvas swing that sat in the weather for 10 or 12 years before it finally gave up a few years ago.
