Those who are interested in H&S may have to watch this from behind the sofa!
Would you work in a ramshackle foundry in bare feet? Would you pour molten iron in open-toed sandals wearing just a cotton shift without even any eye protection? No, neither would I but these guys do and all you can do is admire their skill and courage in producing this work.
The video is over 45 minutes long but is worth watching through to the end.
