A shrink box is a container that is made from green wood with a bottom that is a dry disk of wood that is fit into a groove in the base of the box. The green wood box shrinks as it dries locking the bottom in place. Traditionally these were hand carved. I’ll demonstrate how to turn the box, cut the groove and carve and shape the bottom to achieve a good tight fit. Typically turned wood boxes are made from dry wood, I like this technique as it is a way to make lidded containers but still use green wood.
