You will need

- - a glove or piece of rag;
- - linseed oil.
Find a stalk of bamboo. This plant can grow at his dacha, or even on the windowsill, and very quickly. Suit and an old bamboo rod or a fragment of the curtains, if made from sufficiently long stems. The diameter can be from 2 to 2, 5 cm it's okay if the flute will be a little thicker or a little thinner.
Cut a piece of bamboo about two feet long. About the hardness of bamboo is legendary, so to saw off his best jigsaw with a fine blade. Saw off or break off to one end was a natural tube.
Mark first, it is blower, hole. To do this, from the end, which is a natural tube, measure with a ruler 2,5-2,55 see Mark preferred to make a regular marker. From the mark on the same side, measure 15-20 cm and make another mark. From her back the same distance as that between the tube and the first hole, and put the third point. Make 4 more marks. The distance between them should be equal. Total should have 7 marks.
Get rid of unnecessary partitions. Most likely, in the bamboo flute is not one natural tube, and 2-3. You need only one, which covers the flute from the end. Do it with a heated steel rod. The flutes of other materials thus burn the entire inner part, here you need to only remove the fibrous tube. Heat the rod red hot over a gas burner or on the campfire. The other end hold with an oven MITT. It is best to use a kitchen MITT.
Drill out the holes. Better make it just a drill diameter slightly greater than 0.6 cm Electrodrill in this case should not be used, the bamboo will crack. Hand drill can be used, but turn the handle slowly and carefully. The drill is also necessary to heat red-hot. Potholder in this case will be of little help, so use pliers.
Coat the inside of the flute with rolled fine sand paper. Sandpaper can be wrapped, for example, Cycling or a long knitting needle. If necessary, expand the inner diameter of the flute. Remove the charred areas around the holes.
