I just wanted to say that you should try burning the
bore and finger holes out with metal rods. I think
burning is easier/more fun/and you can make a finger
hole larger easier without the risk of cracking or
damaging the skin of the flute. When I was drilling
holes it seemed more difficult plus it's not very
traditional. Also it's fun and easy to experiment
with making the natural bore of the flute as large as
you want. just use a larger rod than the last and
keep burning the bore larger. this way you can make a
nice tapered bore if the bamboo your using doesnt have
much variation in bore width from one end to the
other.
P.S. actually I know nothing about making flutes. But
I have made about 40 flutes since last year and I
think they all sound great. just recently I bought a
tuner and found that most of the flutes I make sound
great but definetly are not concert pitch. haha but
you only need a flute to be in tune if you play with
other instruments. really i think its best to play a
flute that isnt exact because it represents how mother
nature/god makes everthing. no 2 things are the same.
I would also like to say that when i cut bamboo to
make flutes i first let the bamboo sit inside near my
fireplace. after awhile some of the bamboo is really
cracked, some of it gets small cracks near nodes and
other peices still look perfect. those are the ones I
make flutes out of and none of them have cracked.
The ones that get small cracks near the nodes are my
experimentation flutes where I try different weird
things. and actually these flutes turn out quite good
and have a awesome sound. Sorry if i wrote to much
and bored people but i cant help it.. i love flutes
