[c-r] Any any any old iron (fwd)

[DJ Bryant]

This was on the change ringers mailing list this morning, and I thought it
might be of interest. My understanding was that steel bells were made of
cast scrap, so the content couldn't really be relied upon! Those I've seen
are full of impurities - we had to drill small holes in the Basaleg ones
to fit safety hausers for the clappers, and this confirmed that there were
a lot of impurities. The metal was also very hard, as I recall.

The following message from Elaine Phillips of Randwick, relating to the old
bells, was posted on the ANZAB e-mail distribution list. Does this make
Randwick unique, or other 'steel' bells also actually iron? Or is 'steel'
a variable term - I always thought it was iron with carbon in it.

One is tempted to ask what Randwick would have been like without the
sound-deadening properties.

Rob Keir, Belinda Keir's metallurgist husband has just analysed the metal
from the St Jude's steel bells. They are actually made or CAST IRON not
cast steel!! Cast iron has a much higher proportion of carbon in it and
the particles of graphite (carbon) that are distributed through the metal
has the effect of deadening sound, hence cast iron is used for piano
frames.

We want our money back!!
