Stoppers and crowns
Why do they work?
I'm honestly not sure. One suggestion is that the space between the stopper and crown (which is normally filled with a
cork) acts as a vibration chamber. Another suggestion is that the stopper, which is short, light and held in place only by the
O-ring, vibrates with the air column in the flute. The response of the flute will change if the crown is removed, or if the
little hole in the crown is plugged, or if the space between the stopper and crown is filled in. I have even noticed a change
in the sound and response of a flute when I have fitted a crown made of a lighter wood. (It wasn't as good.) I have now
made crowns in many different materials. Zirconium has been particularly successful.
Fitting
Fitting is easy: simply unscrew the original crown and push out the original stopper using the tool supplied. The tool is
hollow and will apply pressure to the stopper itself, not to the screw. Next, put the new stopper in the headjoint and push
it into position with the tool. The three lines on the tool will help you find the correct position. Finally, push the new crown
into position. The whole job takes just a minute.

A simple, cheap and easy-to-install improvement
to any flute headjoint. Simply remove the crown
and stopper from your headjoint, fit the new
stopper, fit the new crown. The difference in
sound and response is astonishing.
The stoppers are made either of Delrin (a hard
plastic), or of zirconium. The crowns are made of
African Blackwood (also known as Grenadilla).
Both stoppers and crowns are held in place with
an O-ring. Zirconium crowns are also now
available, both in a natural colour and heat-
treated to a beautiful deep mirror black.
Flute players are amazed (and I continue to be
amazed) how the sound of a flute changes when
these gadgets are fitted. Players who use them
have said their flutes have become louder,
smoother and more responsive.
The stoppers will fit almost any headjoint, but
the crowns must be made to measure. I need a
measurement of the inside of the top of your
headjoint (the crown end). Any repair person or
engineer will be able to do this for you in
seconds using a vernier caliper.
