Sorry but The originator of this post is a knob!
Who are you to start banging on about banning air cylinders??
Are you an expert in this field??
The incident happened to a stock maker on the other side of the world, why was he knowingly filling a homemade cylinder??? I wouldn't, regardless if it was a mates!
Sorry and no disrespect to the injured party but stick to whittling wood!
It's do-gooders like you who fekn cause wide spread fear amongst communities like this one!
I wish the chap involved a speedy recovery but let it be a lesson for individuals who play with things they know little about or don't respect!
In 25yrs I've only ever heard of one cylinder having a malfunction ( which has been discussed)
My tuppence worth, good night!
