You say that you didnt criticise todays Fitters/engineeers. Here is what you said,
'Sad really as today's fitters can't even sharpen a drill bit. They waste money buying new ones'.

Where did you hear that rubbish ridiculing top class modern tradesmen like my son who is as good as any Engineer from the past.
You only repeated what Mr Dunn said recently ie he learned most of his engineering trade at Hebburn Tech thanks to the NCB not at the Colliery..
