Flute cork setting gauge

A gauge for testing and setting the cork position in your flute.

The theory is, that for a standard western concert flute, the flute's internal diameter at the centre of the embouchure hole, and the distance from the centre of the hole to the cork should both be the same dimension: 17.3 mm.

The tool has a diameter testing plug at one end. When inserted into the flute, this should just reach the centre of the embouchure hole.

The other end of the tool is a small enough diameter to reach right to the cork, and has a mark centred 17.3 mm from the end to allow you to test and/or set the cork distance.

Obviously you need to ensure that your printer is printing the correct dimensions. Ideally you should check the diameter end of the gauge with an accurate measuring device such as a micrometer or digital caliper. If the diameter is slightly oversize, you could sand it to the correct dimension using wet-and-dry sandpaper or similar - or you could reprint applying scaling on your
