Duplex or Potts Drill Grinding Jig


Has anyone got the relevant drawings for making the Duplex (or Potts) drill grinding Jig?

There were a series of articles in the Model Engineer in 1952 (issues 2632, 2634, 2638, 2640, 2642 & 2644. There were further articles in 1963 & 1964.

I also believe that Woking Precision sold plans but Woking no longer exist.

Hemingway do a kit of castings and bar material with drawings but don't sell just the drawings.



Many thanks to vtsteam I now have pdfs of the articles!
