Tone Hole Gauge with Light

Submitted by dobby on Wed, 04/25/2018 - 21:16

This is a tone hole gauge to check whether a flute tone hole is flat/level. Turn the light on, sit the gauge on the tone hole and you can see where your high and low spots are. 

This is great for those who push tone holes up from the bore instead of filing. You can check your progress without having to take the flute off the dent rod or mandrel. 

Also great if you don't like to leave a leak light in a flute while you're working on the tone holes because of the flute getting warm and your hands sweating.
