Goniostat / Goneostat


The original Goniostat as outlined by Charles Holtzapffel in his 1850 book, Turning and Mechanical Manipulation, Vol. 3 - Abrasive and Other Processes not Accomplished with Cutting Tools. This was designed to work with a flat stone, though now these are used with flat spinning disks, and a newer variation of it is still available.

Lukin designed the Goniostat to the left, and published it in 1894.

Just getting started?
You will need a way of sharpening fly cutters if that is what you use. If you are using carbide inserts, this is probably not needed.
