Thank you John....my feelings about this were strengthened when a woodturner came into my shop a week or two ago. He was an extremely enthusiastic sort, buzzing around the shop and jabbering away, and he kept asking about this process and whether or not I use it. I assured him that I did not, because of the safety record associated with it. He insisted that it was a perfectly safe process and that the people who have died as a result of using it, have done so because of their ignorance of matters electrical, so they should have left it to experts like himself. I protested my point and he then said (and I'm paraphrasing), "...people don't realise that even with airborne moisture in a workshop, the power being emitted by a home-made set-up can ark across the room looking for somewhere to land, if it lands on you, you're dead".
Now in my mind, he strengthened my argument, not his own, but he didn't see it that way, and this is what we're up against. Well meaning people, who may well be skilled at handling such specialised equipment, will only raise the level of interest in it if they keep the process in the limelight and display their results and, as I said before, less well-skilled people will get hurt in their attempt to emulate those results.
