This video number two in a series of flute making videos. How to make a Chinese Flute. This flute is unique because of the membrane that gives it that distinct sound. Look for my other videos South American Flute, Irish Tin Whistle, Transverse Flutes, Shakuhachi or Japanese flute, Native American Style flute etc.
My apologies but the measurements are backwards, they are measured form the sound hole.
First hole, 42% away from the sound hole, then 52%, 59%, 69%, 75% and 83%.
So 148 mm, 183, 212, 248, 269 and 298.
UPDATE - September 4th 2018: The best membrane material I came across is the plastic holder from a sanitary napkin, easy to install, unique sound and little adjustment.
