"barrel connectors".

I can get close using a ruler on the outer part of the plug,
but those pins inside are near impossible to measure.

There are so many variations of them too.

Someone must have some sort of gauge to measure them....

Sort of. I either use one of a set of matching sockets or small
lengths of fine tubing. Sockets are easier to measure using
fine twist drills which are typically sold in sets...

Mike.

outer dia: micrometer, drill bits, nails inner dia: drill bits,
small nails/pins,

Sharp calipers are okay for both.

calipers are good if the points are relatively sharp and they line
up, neither was the case for the device linked to, nor is for most
other cheapie vernier calipers.



I have a couple of Mitutoyo ones that work great and weren't expensive.
Chinese ones are good for scribing circles on copper or aluminum and
other such jobs that might hurt the good Japanese ones.
