The Idea

Cast Bore Flutes are Instruments that have a wooden body, but the bore of the instrument is cast into the wood, using a special Resin. There are a lot of advantages:
The bore is very stable and not affected by moisture. Compared to other plastic flutes made from ABS, Acetal, PVC or the likes they are much lighter. Wood that is not usually used for flutes can be used to make an instrument, a rather porous and light timber has even an advantage because the Resin can bond better with the wood by soaking deep into the grain of the wood and locking the resin tight to the wood.
Blow hole and noteholes are cast as well, so the blow or notehole chimney is made from Resin too. The Timber is well protected from moisture and the Cast Bore flute is practically maintenance free. Only the outside of the instrument needs some care, the bore needs only a basic wipe after playing, but even if that's not possible it's not causing any damage.

The Basic Cast Bore Flute

This type of flute is meant as either entry level model or a flute for practice or use in rough terrain. Something you can take to the beach or play in the rain, without having to worry about it too much.
The Flute Head is made in one piece, they don't have a tuning slide. The tuning can be done by pulling the body out of the main tenon socket if necessary.

The Body is made of one piece and goes down to D and is in the key of D. That is the very basic model.

C-Foot models are also available, the main body has a second tenon to fit a separate C-foot. Their lowest note is D and they are in the key of D. The addition of a C-Foot helps to play notes in the third register.
The same Cast Bore is available for my Standard flutes, for a more professional flute that can also take keywork.
