Creating this stand was quite complicated, but worth the effort. First, a box was constructed with three large sides, a base board, and a door to cover the front. Inside, on the left, a small board creates the compartment for the pulley system, and the Plexiglas container allows the draining of the sand to be visible. A large weight was poured from cement, and two small boards with pulleys were placed at the very top of the box to hold the weight over the sand.
