@salbayeng: The safety committee took possession of it and waved it around at safety sermons.
I remember seeing something maybe 20 or more years ago -- I can't recall if it was on TV or if it was a safety video -- or it I saw it in the UK or the USA -- but it was a true story.
A company had just had a series of safety classes and also mandated that everyone would wear protective eye goggles. A lot of the workers guumbled. One of them followed company policy -- put his goggles on -- picked up a compressed-air nail gun, and started to work.
Almost immediately, a 3" or 4" nail went through the workpiece, ricocheted off the concrete floor, and came straight back at him. It pierced the goggles but they slowed it enough that it stopped with the tip of the nail about 1mm from his eyeball. If he hadn't been wearing the goggles it's almost certain he'd have lost his eye (possibly his brain).
I bet the safety committee are still waving those goggles around to this day!
@salbayeng: Actually my favorite hole making tool is a (hand-held) plasma cutter, you can carve any shaped hole including slots, curved holes , half holes...
Oooh -- I want to try one of those!!!
Often, like the idiot I am, I find that I have no room on my bench/desk top so I "machine" the object on my lap resulting in ripped pants and maybe a scratch or two on my leg. Plasma may turn out to have a more significant result!
@Salbayeng... "I imagine a rhinocerous would make a decent size hole in such a wall?"
Well yes, but where I lived there were not too many of them nearby. One place I lived we did get Kudu (large antelope with spiral horns) eating our roses at night, but nothing worse than that, Elephants have been known to demolish stuctures that are not too well built by rubbing their backsides against them to get a good scratch. But most animals are too clever (and shy) to try this sort of thing....
One of the things I picked up from Harbor freight a decade ago? , was a 2-stroke petrol driven drill, I used it to drill heaps of 1" holes in fenceposts , then having put up a km of fences , sold the used drill for twice what I paid for it.
Reminds me of the time I went to a great deal of trouble to carry a $20 bottle of excellent Hunter Valley chardonney all the way across the pond to friends in Buffalo, only to find the exact same wine in a bottleshop on NF Boulevarde for $10 ..
