Downloadable CAD drawings for the John Wilding English Regulator

The following drawings in Autocad DXF format are a selection of the drawings used as input to CAM/CNC systems to produce clock wheel blanks for John Wilding's English Regulator clock. All measurements are in inches.

These drawings were used to produce G Code in Lazycam and imported into Mach 3. The parts were cut out in 1/16 or 1/8 in. brass sheet  using a Taig CNC mill. However, these drawings should not be deemed universal as some constructors may want slightly larger O.D.s so they can turn them down as they see fit.

This Web page should be regarded as under construction. At some point, more drawings and photos of the parts may be provided as well as the G Code generated by the CAM program.

The teeth will be formed with a Sherline rotary table mounted on the Taig mill. Due to a move and six-month storage, all equipment is still being set up as of early 2012. As the shop is set up and running again, more information and photos of the CNC system will be added. A partially complete version of Wilding's Large Wheel Clock is shown at the end of the Collections page. Some of the smaller wheels were cut out on the CNC Taig. Parts in progress are the collets, barrel and click spring.
