I attended John Landell’s Vermont Flute Workshop in 2009. This was an amazing experience to work alongside and learn from a true master craftsman.
Here is my photo journal of the adventure.

After this the trill arm still and spring hook still need to be soldered on.

These are spring hooks that are cut from U shaped tubing. He applies silver solder to them before cutting them, they will be easier to solder this way.

Soldering the spring hook on.

A hole .035 inch needs to drilled for the spring. Note that Landell is holding the flute with the right while guiding the drill with his left. He did it perfectly.

Doing the final touchup.

Ahhh! The key is done.

And I leave beautiful Vermont till another day.
