a Simple Bamboo Flutes (Bansuri)
1- First take the bamboo
and clean it. Now put the bamboo in the jaws of a wood
Figure No. 36
2- With the bamboo firmly
clamped in the jaws of the vice then drill out the nodes
with a variable speed electric drill. Then move the bit
through the length of the bamboo. It the bamboo is very
long then some times it is needed to drill the piece
form both ends. Figure No 37

3- For making mouth piece
for this instrument, it is important to smooth out the
nodes as much as possible from the inside. It can be
easily done with the round file.
make the mouth piece, start with a piece of wooden dowel
of appropriate diameter to fit snugly into the mouth
piece end of the bamboo.
5- It is much easier to
make the cut a way in the dowel before you cut it to
length. So cut the dowel at first to a length of about
100 mm. Put it in vice and make the recess of about 1
mm deep. It can be done with a flat file or some thing
like that. After making the recess, cut the final length
Figure No. 38
6- Then cut a groove in the
top of the bamboo on the same face as the finger holes.
It can be done with the combination of a razor knife and
sharp chisel. The exact dimensions of this cut away are
not critical. The 20 mm distance is important though
since it needs to be the same as the length of the dowel
piece which will insert in the mouth piece end.

7- After cutting recess
then make a flat groove on the inside of the bamboo at
the mouth piece end from the end of the flute to the
start of the cut a way. When this has been done the 20
mm bit of dowel is inserted gently into the mouth piece
end so that it just aligns with the beginning of the cut
a way. At this stage blows into the end and get a sound.

the holes have been marked they need to be drilled. The
best way of doing that is with drill press. So drill the

inside of finger holes needs to be cleaned up. Use the
round file or a bit of rolled up sand paper.
