spkjpr,
Me and my Dad were actually working on the same plant at the local Cheese Factory and there was a guy grinding Stainless, what a ( ) rackett!!.
I told him to get his ear-muffs on, he agreed!.
That was cool!.
But, spkjpr, it's just like the old "smoke-eaters" we had in the Fire Service before Breathing Apparatus was bought out, hear them cough and choke these days, those that are still alive!. [Linked Image]
