Software for Making Volvelles

Other Kaleberg Software


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.
