    One of our Church’s bells cracked.  At 500kg (1100lbs) it ws gently lowered from the tower and taken to the only remaining bell foundry in the UK.  It could not be repaired, so a new bell was cast a week or so ago.  The foundry has been on the site since 1859 and is mostly unchanged as is the process of casting.  Bell metal is heated to 1200 deg C (2200 deg F) decanted  and craned to the mould.    The metal is allowed to cool to 1000 Deg C (1830 deg F) and poured into the mould.  Most of the mould is buried in a sand pit as if anything goes wrong, none of the casters  want 1000 deg C bell metal spilling on their feet.  The bell is cooled for 4 days where it is, and then removed from the mould.  It is then carefully tuned by shaving bits off the inside.  If too much is taken off then another bell has to be cast, so it is a highly skilled job that can take a couple of weeks.

    Attached are some images I took of our bell being cast.

    Jeremy, it was at the J Taylor Foundry in Loughborough.  It is the only bell foundry left in the UK now that Whitechapel in London has gone.  Over 100 years ago they cast the biggest bell in the UK, the Great St Paul, 15  3/4 tons, still ringing in the SW tower of St Pauls Cathedral in London.
