The top joint and middle joint of both of my oboes do not line up perfectly. They meet, probably 1.0 - 1.5mm, off center. I can see sliver of crescent shape misalignment when I look through the bore from the bell end.
It does not seem to affect the way either oboe plays. But I am not really sure. When 3rd octave c# and d misbehave, which is rather common complaints I have time to time, I usually adjust my reed to correct it, and it works most of the time. I wonder sometimes, however if this misalignment may contribute to this problem.
I asked two prominent oboe techs, one from the east coast and one from the west. They have just opposite opinions. I do have little bit of oboe acoustic background. It should matter theoretically but until I look through the details of the equations, I cannot tell if it should affect the 3rd octave c# and d and how much. Beside, I no longer have necessary tools to work this out.
Anyone here have any experience on this?
I attached a photo.
Also, anyone know how to delete unintended post?

My Jarde's upper and lower joints have a 1-1.5 mm gap, because someone had inserted a metal sleeve years ago. Like you, I do not notice an appreciable difference in the playing of the instrument. (It also has a noticeable 'bend' and is a very old instrument.) My own inclination is to leave it.
I hope someone more technical than me can respond to your query.

If the bores are out of alignment, then there's not much you or anyone can do to gt them to line them up perfectly. I wouldn't worry too much about it as it's fairly common.

I have to believe they were not misaligned at first.. How do they get misaligned?
