I was also thinking why can't a step switch be used to turn it on and off?  That way when you have the probes or clips in place just hit the switch and let it do its business.

I am thinking of something like a dead man floor model step on it or let off of it to stop it.

That is what I use, and I absolutely recommend that as the first step in designing a system. HF sells two types. Go for the momentary that only powers when you step on it. The other is a maintained switch, that stays on after you step on it, and powers off when you step on it again.

I would not use my system without it, primarily for safety, but it also allows for instantaneous control for quality.

wonder if different salts would have an effect (calcium or potassium chloride instead of sodium)....

You have to keep in mind what the solution will do the the wood if you use different salts.  For example, the baking soda solution darkens birch quite a bit.

I haven't tried those different  ones,but have heard that regular  salt and epson salt don't work as well as baking powder.

Wow ,have been away camping for a bit and am glad to see this thread take off.
What I did was ,I got a microwave from the thrift store for $15.So that was my cost.
From what I read, a neon set up works better,if you have access to one.
My set up is exactly like the pictures from Tom Brouilette above with the PVC wands.
I also sometimes use alligator clips, attacked to the bare wood or hammer in a small brad nail like Don French does to attach the clips to ,easier on a round object.After the burn you can't see a hole from the brad nail.
A problems I have, is getting good conductivity .Using a mister bottle of baking soda and water while it is burning seems to help.
Love the examples in pics above. Thumbs Up

Safety in doing this is of utmost importance.Doing the wrong thing could kill a person,be careful.




Rob

Just a question on the misting while it is burning.  Is there anyway the spray can somehow cause the current to jump from both probes and get a shock that way?

I am putting together a demo for my club.  I have a powerpoint presentation showing how I put my rig together.  I'd be happy to share it with anyone who is interested.

Tom
If you wouldn't mind sending to me, I'd like to include your presentation in our Tutorial section. I think it would be a great addition to our forum.

With your permission I would convert it to a format that would be easily viewed on the web.

Thanks

Arlin.This is an excellent video describing the differences between a Neon transformer and a microwave one.In the video he talks about misting with a mister bottle during the burn.he also demonstrates using the mister to somewhat controll the burn .Check it out.

I took a look at Tom's handout and while I beleive it fine to present in person during a club demo, it doesn't address enough information for for people inexperienced in electrical work to view.

I just don't want it on my conscience if someone got hurt so I will not post it here.

My apologies

Most likely a good decision Ron, no matter how attractive the results are I can't see doing this method w/o a complete understanding of the process.

I can say these safety tips are good

1. Use quality lineman gloves. Ones without pin holes which will also conduct electricity.
2. Stand on a rubber mat and put the wood on a rubber mat also.
3. Hook up one probe at a time and do not plug it in until both probes are set.
4. Wear rubber soled shoes or boots and best if they do not have metal on them.
5. Wear face shield or better yet a Arc shield to protect the eyes in case of a splatter

That is off the top of my head but I am sure there are a few more

Saturday I did receive my Neon 12,000 volt .03 amp in the mail and waiting for my friend to help me set it up.

Having wasted my money on four different neon transformers, I can add to this thread by saying that you cannot use a neon transformer that has a GFI circuit built into it. Most of the new transformers have this since it is now mandated by law. I spoke to a tech at Allanson, a leading manufacturer of neon transformers, and he told me that any of their units made after 2003 would not work for wood burning, as they have the GFI circuit built into them.
