Aimed specifically at the engineer for use in the workshop, this guide is intended to take away as much as possible of the mathematics and mystique from calculating gear ratios, so that the more enjoyable work of using your lathe to make things becomes as easy as possible. Topics covered include Myford and other types of lathes, approximations and alternatives, errors and their significance, and the non-gearbox mini-lathe.
