The Leach Treadle Wheel
Though electrically-powered wheels are of course common, today, many potters still prefer to throw on a human-powered wheel. Whether chosen for aesthetic purposes, out of a sense of traditionalism, or simply for exercise, these human-powered designs usually incorporate a heavy flywheel which is brought up to speed, and kept there, by the operator’s leg muscles. .A step up from the simple “kickwheel” design is the “treadle” wheel, which adds a crank and reciprocating pedal for greater mechanical advantage and smoother operation. And among designs for treadle wheels, the “Leach” type stands out as a popular favorite.
