Dirty Jobs- churchbell maintenance and repair

I remember one episode of this show, which was about churchbells, and how they are taken care of. Indeed it's a dirty job. They've shown the tour of the local foundry, where they make the bells, and clean and repair them. Believe it or not, the start of making ga huge church bell starts off with horse poop. The poop you can say is used to create the mold and is used when pouring the hot melted metals into the mold. It hold the shape of the bell together, as it goes through a cooling process and sets to harden. Amazingly when they show the process to repair and restore old churchbells going over 100 years, you take on a strong appreciation of such a musical device. But that's not all, the guy had joined the team in a job of going into a church, and climbing up to the belfry to do some maintence work on their bells. They had to scrunch down really low and crawl under the bell to clean and lubracate the genetator and parts, which automatically ring the bells. At times the poor guy had accidentally hit the bell as he took out the clapper and he had almost gone deaf. Not to mention whem the bells had begun to play the Angel's praise or something when the church bells ring 13 times. The poor guy was inside the bell as it rung. It was a grand experience as I wondered what the inside of a belfry looked like. But it was no picnic, as the inside was covered in pigeon poop, and dead pigeons as they had somehow flown into the belfry and never got out.  After a long time, the job was done, they went back downstairs,  and the owner had flipped the switch to test out the bells. And they had rang out beautifully. What a job, but it's necessary to have those bells to ring to call everyone to worship
