Ingo's pedal-powered grinder / sharpener


Ingo converted an older-model stationary exercise bike into this pedal-powered sharpening stone.

The bike had a very simple tensioning system consisting of a strap around a heavy fly wheel.  This made a perfect set-up for a chain-drive tool.  See a photo of the chain-drive system with gearing for running the wheel at different speeds.
