Natural means that you knock out the joint partitions on the inside, smooth
them down as much as possible (using a garibo--a sort of round rasp on a
metal rod), and auger out a hole at the root end. After the utaguchi is made
and the finger holes drilled the whole inside is coated with lacquer (or its
chemical equivalent) to seal it. Generally this is done in several
coats--first with natural lacquer (pure--without colorants) as a sealer and
then with the color of your choice. Uncolored lacquer is thinner than its
colored counterparts but dries much quicker and harder.
I don't think wood putty is suitable. Here in Japan there is a kind of epoxy
wood putty (two part stuff) that sets quite hard. The sensei say that car
body filler putty is also quite good. That's what I would go with if you
can't find the epoxy. The epoxy, BTW, is also not very sticky, and it takes
some skill to get it to cling to the inside of the bamboo. I can give you
more details on this if you are interested--write and let me know.
Regards,
Toby
