Re: Use For Spring-Loaded X,Y,Z LED Edge Finder

To The Curious:

I bought one of the following edge finders years ago. Never really
used it, since (like all the LED edge finders I have), it's not nearly
as accurate as a normal edge finder, especially being as it's spring
loaded.

Now I was setting up the 3D profiling operation on the following part
last week. Picture resolution isn't so hot, I need better lighting,
or maybe a new digital camera. It never did work very well for small
parts.

Picture the 1/4" wide "tang" with the 5/8" bored hole in it being held
in a vise with the 10 degree flat bottom (before profiling), sitting
kind of like in the second picture. I wanted to find the center of
the 10 degree angle in relation to the center of the "tang". So what
I did was edge find the back vise jaw, move out half the distance of
the 1/4" "tang" or .125", then put my X,Y,Z spring loaded edge finder
in a holder, moved out half the diameter of the tip (.100) then
brought it down until the edge touched the angled surface of my part
and the LED's lit up. Recorded the Z value in the control, moved the
edge finder to the surface of the back vise jaw and brought it down
and touched it(LED's lit up. Wrote down the Z value, subtracted the
two readings, then made up a Jo block stack at that dimension, and
set my tools off
of the Jo block stack.
Was that clear as mud? LOL

Anyway, my point being, that that was the first time I actually
thought of a use for that spring loaded edge finder. I didn't even
think the batteries would still be good after all this time.
Just sharing a little setup tid-bit that might prove useful to someone
in the future.
