Every once in a while, I put my 4 piece flute together and it looks a bit crooked to me. Can this happen from chunks of cork grease in the bottom of the tenon joint making it not completely flush? …then there are other times the the flute looks perfectly straight to me.
…or maybe it is simply a function of how many pints I have had. 
Fluteplayer’s moderation tip: put it together crooked, and when it starts looking straight, you’ll know you’ve had enough.
OMG…I just Googled “peyronies”.
Sorry, I couldn’t resist. Rather Presidential, too, so I hear.
I did not know that.
I believe that such an intimate tidbit will have me wondering which one all day despite my best attempts to forget. Damn you, Wolvy!
Here is a little trick I learned line the joints up perfectly and put a small scratch extending over the joint on to both sides, that way you will be able to tell real easily.
Avery, are you still talking flutes?

Does this mean that my D flute can turn in to an Eb after 50-60y ?
