Arch, I just got through testing the strobe idea, and I think it will help.
I chucked a 16" wooden ruler approximately midway in the jaws of a spigot
chuck, so it was spinning like a propeller. Using the strobe, I was able to
make the image stop, or drift in either direction. I was able to read the
numbers on the ruler even with the room lights on.

My main concern is whether you can find a strobe light like this. Mine is
probably 40 or 50 years old--I got it as a junk or surplus item, and I
believe this is actually the first time I have used it. I'm sure there are
new units available, but at what price?


you might note that strobes can have very adverse effects on some people..
especially those on some types of medication...
They had to take them out at my wife's old job at an health care place because
they can cause seizures or something..
