walk into the mechanical workshop, a room of machines. Lathes and milling machines, filing benches and vices, look into the side room, here is the smith, everything in close order.hammers, presses and welding machines.
Over the weekend the father and son team had attempted to remove a ball bearing ring from a stub achsle belonging to the trailer for the family car.
The bearings were stuck, so use a press, a pulling claw to remove them.
To try and remove them.
The wheel is now bent, the bearing is still insider, a disaster.

Ask the man operating the milling machine if there is anything to be done with this bent piece of metal with the bearing still stuck in it. The comment " done with no feeling for anything whatsoever, how did you expect that to work?"
And laughter, pleasure at the signs of incompetence so apparent to the qualified eye.

The workshops master enters, takes one look, and says, "bad". But still, it could be worse.
He walks over to yet another workshop, the place were the trainees are.
He borrows a tool.
He scrapes away the surplus metal.
Puts the whole thing in a press.
pulls a lever.
PoP.
Out comes the bearing.
And he says that later on, he will straighten out the other bent bits.

It is good to have a friendly master mechanic about to fix the mess made by amateurs.

Nothing is as easy as it seems.
