stuck mouthpiece on generation

@Tommy

If there is no tone hole puller or combination streacher&shrinker the hot water soak is the way to go. Sometimes it may have to be done twice. I have found with the hot water soak that after removal of the head. Make sure to remove all traces of the glue or when it is replaced it may reset itself. A flat note is more easy to fix than a sharp. Several of my generations have oval holes but are in excelent tune with themself.

Well, I tried a few more times to remove the mouthpiece and it just wouldn’t come off. I’ve given up for the time being.

The problem with the C, and also F, Generation mouthpieces is, the sockets are too small for the tubes.

This is true of all of them in those two keys due to the way the molds are configured. If you actually do succeed in getting the mouthpiece off, once it’s cooled again, you’ve still got the same problem. Whenever you want to adjust the tuning, you’ll have a fight on your hands moving the mouthpiece.

I intentionally crack them using two drops of acetone at the place where the tube goes in the socket. Then they come right off. I replace the mouthpiece on the tube, which opens the crack about half a millimeter. Then I wrap polymer thread around the socket and soak it with epoxy to reinforce it and establish a new, slightly larger, inside diameter that’s appropriate for being able to adjust the mouthpiece normally. This is more difficult than moving the toneholes, but it produces a result that’s tunable.

Best wishes,

Ah-ha! I’m so glad I gave up before I totally ruined the head trying.

All decapitation attempts have failed thus far.

One time I got the head off a gen C by putting it head down in the sink
while I did the dishes with running hot water and washing-up liquid.
Actually I had to do this 3 times (3 different loads of dishes).

And as has been said, when it finally came off (I was wearing those
dishwashing rubber gloves, btw..) there was a load of glue stuck to it
and to the tube, which had to be scraped away.

Then, I put some vaseline on the top of the tube so that it wouldn’t get
stuck going back in, and it was just fine, I gave it back to the happy
owner all put together and nicely sliding.

And then, the owner lost the head!

“And then, the owner lost the head!”

lesl, if you hadn’t added that line I’d probably have continued being oblivious to the WWW just below it that took me to a great site! I’m so glad I found your music!



Sorry. William. for the subject change.

Oh heavens, thank you Mack. I wondered what you were talking about at
first. I haven’t thought about that web site in a long while! Spurring me
on to try and put something recent up there.

Back to the subject I’ve a red Gen Bb, which has really gone through the
mill. It took a lot of soaking to get the top off and then the insides started
peeling, so I had to scrub that out as well. Eventually it got sat on or
something and now the head is held on with electrical tape. (but at least
it stays on!)
