I have been looking for a way to measure the holes in Jewels so I can organize my small collection.
I have a JKA tool for the outside diameter but I have no way of measuring the inside diameter of the hole.
Correction I have a Swartchild tool for measuring between 0.6mm and 2.0mm but no smaller. I'm guessing I might need 0.01 increments but what are the standard sizes?
Am I overthinking it or is there a tool out there made for the purpose.
I was looking at a Starrett Pin Gauge set but I'm not sure of the sizes I might require.
Any help would be useful.
