Closed Plexiglas & Walnut Box
A request was made for a closed box for damp outside
use and, after a number of experiments and prototypes were made and
discarded, the following design was chosen.
The box is made of two 1/4" Plexiglas panels that have a slot cut into them to hold the top and bottom pieces of Plexiglas. The sides are made of blocks of genuine Western Pennsylvania walnut, cut from a tree at a friend's farm.
Two screws on each side fasten the left wood block and only one is used on the right side to expedite access to the inner workings of the unit.
