Notes: | 1 [value] |
Lengthwise and Crosswise tone hole angles are measured in reference to the axis of the bore It is a crude approxiamation based on a sketch of the tone hole undercutting (±10° or 15°) |
2 [value] |
Undercutting angles are relative to the tone hole axis It is a crude approxiamation based on a sketch of the tone hole undercutting (±10° or 15°) |
