What is it called and how is it used?

A scale and a gizmo $485.? Guess I don't know how it works , seems pricey tho
 
The scale is not for sale, just the Edge Finder. Pricey. maybe to some, I paid $350.00 for mine new with the wooden case and paperwork 10 years ago. Factory ones are scarce. Gizmo is really not a fitting word for it.

"Billy G".
 
For the inquiring minds, this gives an idea of how the edge finder works.

  • Precision ground, allows workpieces to be indicated within accuracy of ±.0001".
  • If hole or slot is indicated to centerline of spindle, the edge of workpiece will automatically be on center line.
  • Avoids calculation errors by eliminating additions or subtractions.
 
Wow, that is a cool indicator. A test indicator of some sort. Kinda looks like a last word type from the Starrett co. No 711.
