You can make nice things from old junk. (And Mexican tile...)
A reader writes that old deck boards can be recycled to make new things, such as a step for a hot tub. Way ahead of you! In our house in New York, we had the deck rebuilt, and there was a pile of pressure-treated lumber to dispose of. We could have paid someone to haul it away, but have you seen the cost of lumber lately? It was in good shape, other than it was splintery (never pressure wash a deck!) and had nails in it.
But Mark got to work and made various things with it. I made a frame for a pottery kick-wheel that someone gave us on Ithaca Freecycle. It was just a wheel, shaft, head, and two pillow-block bearings.
