Anyway, I was looking around flutedom and noticed something which referred to a Powell flute with a Cooper scale. So, in looking that up, I found this, which is a link to a Google cache of a page I couldn’t load. The actual URL is this which might also work.
Anyway, he describes an interesting procedure for tuning a flute. He says to start with the cork position such that the distance from the center of the embouchure to the cork is EXACTLY the same as the diameter of the headjoint at the embouchure. Obviously, that applies to the Boehm flute’s tapered headjoint. However, please, someone else read the above links about finding the acoustic length of a flute. And about tuning and cork position.
Is this a good algorithm to use? I always wonder if the cork is in the right spot.

Yes, that’s what I was always taught. You can start from there, and if it’s still impossible to play your octaves in tune, you can fudge the cork around as necessary. Rocket science it’s not. In addition to Terry’s suggestion of comparing the three D’s, I also compare the two fingerings for middle D (oxxxxx and xxxxxx).
