I’ve made a few flutes, but this E4 is the lowest one I’ve tried, and the first one where I’ve had this problem.

I can’t get the highest note to sound - see video. I’ve tried moving the bird fore and aft, but it doesn’t seem to make any difference. I’ve tried smoothing out the air channel, and tried making the splitting edge crisper with little files and those things didn’t seem to help either.

Any suggestions?

By the way, because I hate routers I made the flute body by gluing up 8 narrow strips with edges beveled at 67.5 degrees into a hollow octagonal prism. I made several higher pitched flutes using this method and it worked well. More details available if anyone is interested.
