I keep a 6" section of an old set of strings handy - I always use lights of the same dimensions. When I have a nut slot cut, I run the appropriate piece of string through it a few times to check for tightness.

>> There was a time when I could hear a particular frequency of about 23 kHz associated with the cathode tube of a TV, but I have not heard it since I was 13 or so??

Flat screen TVs don't use a CRT. :-)

The system used in the US specified a line rate of 15.75 KHz. The flyback transformer operated at this rate to create the voltage that drew each horizontal line on the screen. This xformer is what created the noise you heard.
I used to fix TVs and I lost the ability to hear the flyback when I was about 40.

A luthier told me the nut slot should be about 3 thou wider than the string diameter (with teflon tape you may want it even wider).

To cut the slot I have feeler gauges that I cut teeth into using a dremel, but do the final bottom cut with torch tip cleaners to ensure the bottom is rounded instead of square. You can do the entire cut with the torch cleaners, but they don't cut very well and are flexible and difficult to work with - so the process is pretty slow.

This is what I like to see for a nut on a 3+3 headstock guitar
