The geometric slide-rest is an implementation of rose engine work where the cutter is moved according to the rosette's shape and the headstock stays fixed. It was designed to allow for implementation of ornamental turning on lathes with fixed headstocks.
The approach was created and patented by Captain Richard Pudsey Dawson in 1870. It was noted in Norman Tweddle's book, The Rose Engine Lathe, as one of the nine appliances for rose engine turning other than the rose engine lathe (chapter 2).
Paul Cler implemented a number of lathes using this approach.
