Someone from my club demonstrated this technique at our meeting last Sunday. He had made his burner from a transformer he had removed from an old microwave that he had gotten from a thrift store.

I'm a little nervous about trying it now.  Undecided

Maybe it is better off to buy the setup than trying to make it at home if you're the least bit unsure about making one and not killing yourself in the process.

All you need to do is not get one thing insulated properly and Zap & Sizzle are your buddies.  Shocked Shocked

Tom... Yeah, i noticed that as well.

As per Wikipedia:

Electrocution is death caused by electric shock, electric current passing through the body. ... Roll Eyes

Don't do it if you don't know what you're doing. Mine works great - - had to tone the microwave trans down cause it was too "hot". I don't use it much, but when I do, it's total concentration on safety.

IMNSHO
Any system that has hand held probes are NOT safe. There is a commercial unit available that has hand held probes, COME ON, really! That means any leakage through insulation will go up one arm through the torso and out the other arm, most times equals Death or very serious injury.
Any activity that requires handling electrical wiring should only done with the power OFF. When I made my burner the supply power goes through two hand switches on a board far enough apart that both hands are required to energize the Transformer. If I want move a probe I have take one hand off one switch and the power is shut off. Also even with power offf I only use one hand to locate the probes on the work. It is very unfortunate to hear of such an accident but it does not surprise me with all the dangerous YouTube videos out there.
If you don't understand the hazards don't try this.
If you have to modify an electrical device, aka MWT, then risk of incident is high, and In my opinion not worth the risk.
We and we alone, are responsible for our own personal safety, whether turning or burning. Stay safe!

I realize this is your opinion Bert and you don't like the design of the retail units but be careful.  (this is the type of thing that blurs the line between opinion and fact)

This sounds an awful lot like No tablesaw is safe without a SawStop sensor mechanism. I disagree.

It's a difficult thing to prove that something is or isn't inherently dangerous. There are however some people, who's capacity for ignorance of the very task they're performing can be staggering.

IMO it's ultimately the operator that can make a tool safe or unsafe. Just because it's possible to injure yourself while using a tool doesn't necessarily make it unsafe.
Almost every tool in my shop can injure you in one way or another but I don't consider any of them unsafe to use.

Point taken Ed, just my many years in the electrical field. I agree with your comments on shop tools, main difference is that one can see the bitey bits, not so with electricity.

Holding the probes is like standing under a loaded forklift (or similar). Dumb.

The retail unit does use a foot operated "dead man" switch.

I know it's easy to get frustrated (believe me I know) when it comes to unsafe tools and unsafe users. I have more of an issue with the users, they have a habit of making the tools look bad.
Unfortunately history has taught us that people are going to do what they want, no matter how much advice or warnings are given to them.
My number one rant over the years has always been the same.
Many people that use tools regularly either do it without completely understanding what the capabilities and limitations of their tools are or they become complacent and loose respect for their tools.
I'll stop there before my blood pressure rises too much.
Work safely everyone

This was posted on the Wood Central board yesterday:

New AAW policy just announced (in part because of this death):

It is the policy of the American Association of Woodturners (AAW) that the process known as Fractal Burning is prohibited from being used in any AAW-sponsored events, including regional and national symposia, and that AAW-chartered chapters are strongly urged to refrain from demonstrating or featuring the process in chapter events. Further, the process of Fractal Burning shall not be featured in any written or online AAW publication, except for within articles that warn against its use. AAW publications will not accept advertisements for any products or supplies directly related to the process.

The arrogance of the AAW administration to make such a statement is disappointing. In light of the many dangerous activities that turners face with unknown inclusions and the real potential for injury from flying objects, they should quit posting the artistic dangerous woodturnings as well if they are truly interssted in safety.

I tend to agree, it does seem like a bit of a knee jerk reaction but that's just my opinion.
The funny thing is that with electricity, there are cold hard facts about what will and won't happen.
With woodturning you never know what you're going to get manipulating a natural product. Every piece of wood is different.

My point exactly Ed, with the electrical hazards so easily identified and the mitigations very easy to implement, a stronger message that speaks to education rather than exclusion would serve the audience much better.  My opinion.
We all are responsible for our own safety.

in today's world that very often appears to have a lack of common sense, i am more worried that the AAW announcement that fractal lichtenberg is forbidden will be answered with a increase in people trying it out. 50 years or so ago, the words "do not try this..." was taken as a good warning. today, too many people consider this warning a challenge.

I have a feeling you're right Dave.
I'm of the same thinking as Bert on this, it's striking to me that the decision (reaction) was to ban rather than educate. Which only adds to the allure of the "forbidden art", which feeds right into your concerns.
They definitely didn't treat this in the same manner as when a turner gets injured. When that occurs, they double down on the safety for a month or so. Then slowly, we all collectively let it slip into the background until another accident happens and the cycle repeats.
