Re: [Hornlist] New bell problems

Hi Hoss, 

thanks,

The bell and tail are apparently the correct specification for the Holton 
model in question and were ordered  from Holton. (Even though the metal 
thickness is completely different from the original)

Would this difference in thickness make that much difference to individual 
notes?

Where the tail is attached to the instrument, the joint is not as clean as I 
would have expected - it's as though there is a slight kink in the circle.

The repairman who had done the job is very experienced and well respected - 
I'm in a fairly difficult position between him and my friend!

Thanks again,

Lawrence

As an off-shoot of this problem

What steps should be taken to help assure that an instrument repair or
modification is successful?

I'm thinking along the lines of somehow play-testing a new bell prior to
final installation, if that is possible. Or, verifying that the new bell is
really identical to the old one, by measuring, etc..
MY personality is that I would like to do these tests myself (with help and
supervision from the repair tech). 

What about replacement of other tubing.

I know that converting to screw-bell has a reputation for giving good
results, but the bell flair is not (usually) changed in that situation.

Hi,

It sounds as if the taper isn't even throughout the bell and this is resulting in bad 
notes.  Some times this happens especially when from the factory.  The metal might be 
thicker if I'm not mistaken they hand spin there bells?  That one seam by the 
repairman might  be where the problem lies.  If there are any unneccesary kinks in the 
taper, bad notes and stuffiness will be the result.  It might be wish to have the 
repairman smooth out the brace by taking it apart and carefully putting it back 
together.

I hope this is helpful,

Hoss

Hi,
It sometimes happens when soldering the joint between the bell tail and the 
first branch that excessive solder accumulates forming a glob inside the 
connecting ferrule. This can cause stuffiness and some partials to play out 
of tune.

[Hornlist] New bell problems

2003-03-08 Thread YATESLAWRENCE
A friend of mine has had a new bell fitted to her horn after an accident.  
Now she finds that the horn doesn't play half so well as it did before - 
there's a stuffiness about it and it feels rather unstable on a few notes, 
especially it seems on those using just 2nd valve.  it's a Holton full 
double.

She has spoken to the repairman who can find nothing wrong with it, although 
the metal of the new bell is thicker than the old one. 

Has anyone had this kind of problem or can anyone offer any explanation as to 
whether a new bell could affect the blowing of particular notes, or should 
she be looking for other causes?

All the best,

Lawrence

Sounds like you got something with a less resonant bell and a smaller throat.is it 
just the bell that was replaced or the tail to?  It might be too much metal in the 
bell in too many wrong places.  If the bell was not spun evenly you may have a 
problem.  I've noticed my Atkinson flares are very heavy and not very resonant when 
flicked, but it gets the job done in the concert hall.  Let me know what kind of flare 
and how much of the bell we're talking about and I might be able to solve your problem,
