What could possibly go wrong?

[lynx42]

My father had a rear wheel bearing on a 1954 'R' type Bentley seize up and after removing the rear axle, placed the axle in a press and proceeded to try to press the bearing off.
He had the press up to 60+ tons when the phone rang in the house. Mum answered it and called Dad to the house to talk on the phone.
As he walked back to the shed across the back yard, there was a massive bang in the shed and bits of schrapnel came flying through the steel walls.
The bearing cup had exploded into many, many bits and would have killed the old man had he have been there and not called to the phone. He was very lucky.
