Measurement Question

[DJKeys]

I was wondering why shaft diameters are always expressed in millimeters (12.5, 13), but joint and butt diameters are always expressed in inches (.855, 1.26)?

Many of the tips from way back came from France and were measured in millimeters. So it continued to be the standard. So that is how the public was educated on tip size. On the other hand USA Cuemakers started out using Dial Calipers to measure other dimensions just like all USA machinists use and that became the way they calculated all other measurements.

This makes perfect sense, thanks Chris!

Good question........... I am from Spain (Europe) so we use "mm" here but more of my suppliers are from USA (inches) so I have the crazy head with "mm" and "inches"..... digital calibers that can measure in inches and mm were the best invention of the history:thumbup:
