Having had a hankering to make a Watt-style governor but having failed to find any plans to my taste, I decided to design my own. Here it is, with 2D CAD plans produced with Draft-IT (and GIF images of the same) and my construction notes for download. The design is hand-cranked and lacking a valve lever because it was made as a retirement/60th birthday gift and I ran out of time to complete the valve lever (I wanted to assemble the governor before dimensioning the lever).
Inspiration for the design, and especially the proportions, came from Muncaster’s book and photographs I took of real governors.
