In general Brian I agree with that statement. However, where health and safety is concerned, no amount of accusing me of abuse or telling me I am wrong will stop me from giving people sensible advice. Advice which in my opinion will prevent them from hurting themselves.
Deep drilling on a lathe at high speed in a material which is likely to melt and catch, and grabbing hold (by any technique) of something that may start to revolve and is attached to a powerful electric motor are activities which should be avoided. Anyone who thinks otherwise is fooling themselves and any professionals who are promoting such techniques should be ashamed of themselves.
If people cannot learn from their own experience and are too full of their own self importance to take the advice of those who seek to protect them from themselves then it is their prerogative to continue. I sincerely hope no harm comes to them but if it does it will be no fault of mine.
