"Interested in wind and watermills from an early age Jon was further stimulated into a serious study after attending a lecture by Rex Wailes. Following a motor vehicle apprenticeship in Coventry he was joint instigator in saving Wrawby Post Mill from demolition in 1960. He served as Honourary Secretary and later Chairman of the Wrawby Windmill Society. He was technical advisor to the Lincoln Civic Trust in their sponsored restoration of Ellis's Mill Lincoln. He was then offered the opportunity to turn a hobby into a career through Rex Wailes connections and took the position of miller/millwright at Flowerdew Hundred Plantation, Virginia, USA to commission and operate the post mill built to commemorate the earliest known windmill site in British North America.

Since returning to England he has served on the Committee of the Society for the Protection of Ancient Buildings Mills Section, Lincolnshire Mills Group and Industrial Archaeology Group.
