Description of viewer:
The design of this viewer is based on the table top viewers commonly used
with 3D books; however, this one has been optimized for slides. The lens
assembly is made of maple and held together with carpenter's glue. The lens
holes were made with a drill equipped with a circle cutter, and the nose slot
was cut with a jigsaw. The inner surfaces of the lens assembly are covered with
black paper. The lens assembly rests on a base containing a small lightbox. The
base is made of mahogany, and oak molding was used for the outside frame. The
stage for the slides was also prepared from a frame of oak molding and rests on
the light box. If desired, the focus may be adjusted by changing the height of
the stage.
