This drives a 25 stave gear wheel which drives a "wallower" (30 cogs). The "wallower" drives a gear wheel with 31 cogs. This drives a cast iron gear wheel with 48 teeth.

Archimedes Palimpsest Archimedes Palimpsest The Archimedes Palimpsest is a parchment codex palimpsest, which originally was a 10th-century Byzantine Greek copy of an otherwise unknown work of Archimedes of Syracuse and other authors. It was overwritten with a Christian religious text by 13th-century monks. The erasure was incomplete, and Archimedes' work is now readable after scientific and scholarly work from 1998 to 2008 on images produced by ultraviolet, infrared, visible and raking light, and X-ray. All images and scholarly transcriptions with metadata are now freely available on the web at the Digital Palimpsest, now hosted on OPenn and other web sites for free
