My Dad was a blacksmiths hammer boy .. At nearly 15 years old he " drove " a six ton steam trip hammer at a big blacksmithing company in Sheffield in 1925 for several years till he joined up in to the first battalion of the York & Lancaster regiment in 1932- 33 .
It made me realise many years later why he had such a fine tuned sense of rhythm , touch , hand & eye coordination
Back in the NCB days we had the blacksmith/farrier/welders and they were the same a touch like a midwife.
We originally had the steam powered ones and they were phased out for the bigger 15/25 ton hydraulic units and they were fierce compared to steam.
