Who would sell, or who would buy, a silent flute?

Here's a video of the making of such a flute.

Notice the process at 13 minutes where the wood is burned away from the block under the "bird." In my flute, the wood in that spot is unfinished. It probably swelled in Missouri's temperamental climate and blocked the flow of air.

My dear Husband, the DH, has burned the block further and used carving tools to finish the job. I played the part of Princess Summerfallwinterspring, searching the internet and holding the flute steady. The flute is now playing softly and sweetly. It's in a major key, or close to it.

There's a fine crack along a grainline near the top, and I can feel air coming out of it. The DH will drill small holes at each end to stop propagation of the crack and then fill it with resorcinal glue, taking care not to get glue in the bore. The flute should play louder then.
