This mechanical counter works much like an old car odometer counter, or mechanical counters in utility meters. A lever allows for incrementing and decrementing the counter, and a jog wheel on allows for changing the numbers more quickly.
The plans include:
Detailed drawings of every part of the counting machine
Dimensioned 3D views and assembly drawings
Full-scale 1:1 drawings of all parts so you just paste them onto plywood and cut them out with a bandsaw or scrollsaw.
Detailed instructions on how to build it, with over 40 photos
Mirror image digit templates, as used in the construction
More photos of the completed counter
Materials and hardware list
A SketchUp model of the counter, which allows you to view it from any angle, disassemble it, or regenerate each of the views in the plans by clicking on the 'scene' tabs in SketchUp.
