Hi Ron,
I'm using the edge finder in my Golden Goose style keyless chuck on the
mill, (not while rotating )and rigidly mounted in the lathe toolholder (work
turning very slowly by hand for setting up a 4 jaw, etc.). So far I have
found the keyless chuck to be very concentric and repeatable. I usually test
the edge finding at a couple of rotations against my set 0. So far no
deviations have been seen. Much better luck than I've had with rotating edge
finders.
If you used the electronic edge finder rotating, it would flicker as you
suggest. I would also be concerned about wear, because the tip and shank are
made fixed to each other and are not designed to turn.
Hope this helps, Jeff Dayman
