At the Ashburton MenzShed this week, I made a spice rack, up-cycled from free pallet wood. The pallet had a few pieces of perhaps an Australian hardwood with some beautiful colors in it.
After de-nailing and milling the boards and drilling shallow holes with a Forstner bit in the drill press for the spice jars, I cut the pieces to size and joined them with simple joinery and wood glue. Black elastic prevents the jars from falling out. The rack is finished with Danish Oil.
