This is not a machine for making balls, but a shop-made cutter grinder designed by Doug Ball. It is basically a "poor man's Gorton 265" (or New Hermes CG-4 / Alexander 2CG / Deckel S0/S0E / other Gorton 265 derivative). As such it is well adapted not only for sharpening the D-bit / single-lip cutters it is shown making, but also the pyramidal cutters more commonly used in typographical matrix engraving.

It is described in n article by Ball in the English magazine Model Engineers' Workshop, No. 87 (December 2002 / January 2003): 34-38. If you seek these articles and cannot find back issues, they are available as a part of the digital archive provided to current subscribers to the magazine.
