What is an edge finder and how does it work?
Martin sez:
"It is like a balance beam on a knife edge. Pushed latterly and the
beam 'drops'."
Very nice description, Martin. Hmmmnnn, never thought about it before but it makes me wonder; If a
wiggler used horizontally, as in a lathe, would be less accurate because of the force of gravity
added to its moment of inertia.
