[Bell Historians] Mold

[David Marshall]

"It's the fact that they quoted the weights prior to casting to the
pound, as if the weight was guaranteed - one would normally expect
something like, "the bell will be approximately 3 1/2 cwts".

Assuming that they will use one of their standard gauges, why is it
surprising that the foundry can give the c of g and moment of inertia
prior to casting? I would have thought that it was pretty easy to
predict these!

I don't know who published the weight, but obviously it was misleading to 
give it to the pound before casting. Regarding "standard gauges" - they 
don't use them for bells which we specify - they make new each time. Their 
software generates the profile to our specn and also calculate several 
parameters including weight , c of g and m of i, so yes, it's easy to 
predict, but not for the reason that they are using standaed gauges.
