We would have a frequently asked questions (FAQ) file here, except that
nobody asks questions about volvelles. Most people don't even know what
they are.
Volvelles are pairs of cardboard wheels with a common axle used for
looking up information in a table. The front wheel has a legend printed
on it and a number of slots through which various data items are
visible. The rear wheel has the information printed on it at varying
angles, so that only the information in one row of the table is visible
at a time. Rotating the rear wheel lets the user display each row in
turn.
Volvelles are not like slide rules or nomographs in that they do not do
computing. They are simple look up devices.
