How to make bells sound?


#1

I=B4m new here and glad to have found this discussion group. Since I
don=B4t have jewelry schools in this country i=B4ve had to learn
everything by experimenting and books, I=B4ll send pictures of my work
soon.

So here=B4s the question: I need to make about 70 silver bells for
gifts to give on a wedding day to all attendants, and was wondering
what kind of metal do I use for the weight to make it sound better.
I am using silver but the chime is not right. Maybe lead?

What method are you using to make the bells? Although bronze will
"sound" if it is cast silver tends not to and needs planishing so
that the metal hardens.

What sort of clapper are you using?

Lead will not “sound.”

julieta, Bell tuning is both an art and a science. There have been
discussions on bells and bell tuning on ArtMetal and you could do a
search at http://www.artmetal.com/village/search.html and see what
you can find. I am sending you some info I have on my computer
directly to you so as not to bother the list. If anyone else wants
this info, please contact me directly and ask for the bell info.

Hope this is of help.

G’day Julieta. The type of metal used for a bell is dependent on the
type of Tone and the length of decay of the tone you wish to
produce. I will list below some common Bell mixes that I use. I you
wish to use Sterling Silver then you must work harden the metal to
produce the sound required.

Mixes For White Metal Bells

Table Bells.  Sn 97%      Cu 2.5%      Bi 0.5%
Silver Bells   Cu 50%      Zn 25%       Ni 25%  (Contains no  Silver, 
pleasant colour)
Silver Bells   Cu 40%      Sn 60%       (Contains no  Silver, pleasant colour 
and tone)
High Grade Table     Sn 19%       Ni 80%        Pt 1%
German Silver / Nickel Silver.

General Bronze / Brass Bell mixes.

Swiss Clock Bells    Cu 75%       Sn 25%
Best Tone                Cu 78%      Sn 22%  (This is the one that I prefer)
House Bells             Cu 78%       Sn 20%      Zn 2%
Sleigh Bells             Cu 40%       Sn 60% (Silver Colour)
General Clock Bells  Cu 80%      Sn 20% 
General Bell is the same a mix as general clock.
Fire Engine Bells      Cu 78%      Sn 20%       Ni 2%
Large Bells              Cu 76%       Sn 24%
Rail Signal Bells       Cu 60%      Zn 36%       Fe 4% (Basic High Tensile 
Brass)
Gongs                     Cu 82%       Sn 18%
Light Cymbals          Cu 92%       Sn 8%
Heavy Cymbals      Cu 80%       Sn 20%

After Casting any of the above bell mixes the bells must be cold
worked to produce the tone and length of decay required, too much
cold working will cause the bells to be brittle and after repeated
use they will crack.

Hope this is some help
