Assistance needed for a stuffy D#/Eb key
« on: March 11, 2024, 02:08:17 PM »
I just got my PM Artist back from a local technician after I gave up, myself.  Unfortunately, it is no better.  The right-hand index finger trill D# key pad seals quite well (cork), but when lifted to play the note, it is "fluffy" or "stuffy".  It is most unappealing. 

Can anyone offer sage advice as to what I might try, in order to make this otherwise excellent playing horn tolerable to my ear?

It is probably not opening far enough, especially if it's a bit flat. See how far it opens compared to its neighbors. With a strip of med. sandpaper, you can easily adjust it. You can also press hard for a quick test.

It's also very possible that there is some debris in the hole. Without removing the key, you can snake a soft pipe cleaner in there and work it around. More likely, you need to remove the key (an easy one). Then you can see into the hole.

Also, the cork pad may have square edges causing turbulent airflow. While it's off, round the edges with sandpaper.

Great suggestions.  Thanks Windy.  I will attack it and report back.

Like Windy said, perhaps it's not opening enough. I've had that problem when I used a pad that was too thick, or the key was bent. I have man-handled keys and hand-bent them to where I want them before. Then again, I've also broken keys like this, so approach the caveman approach with caution!

This is great, valuable information.
I am committing it to my mental Rolodex.

I removed the key as you suggested, Windy, and checked the bore for debris (clean as a whistle), and then I looked at the hard edge on the cork.  I beveled it a bit, and reinstalled, and BINGO!  Perfect.  Because I do not work with cork (yet) I am accustomed to fishskins and I would never have thought a detail as small as the edge of a pad might create such turbulence.

Dave--I do think the cup rides a hair too close to the tone hole under full extension.  I may have a go at some heat before fitting my brass smooth jaw pliers to it for an ever-so-slight relocation.
(PM keys are generally very hearty)

Great thanks, gentlemen.
