My requirements for portability and compactness drove the design toward a folding model. First, I made a wooden lectern which featured a built-in carry handle. This unit was large enough to hold an opened loose-leaf notebook and other materials needed for presentations.
This lectern was compact, when folded, and about the size of my briefcase. Because it was made of wood, it tended to be both sturdy and heavy. Its weight discouraged taking it along on airplanes.
What I wanted for travel, beyond local automobile trips,
was a lighter weight design. And I wanted it to be able
to double as a lapboard for a working surface on planes,
trains or buses. Hence, I came up with a unit made of
fabric covered masonite board. Fabric hinges served to
assist in folding and hold the unit together. Several
variants of the design shown below were made. The nicest
turned out to be covered with vinyl upholstery fabric,
the thin un-backed kind. Fabric is glued with contact
cement to form a permanent bond and smooth finish.
