Post by: Kbeitz on December 18, 2017, 01:04:49 AM
Started making a high powered pyrography tool today.
Anyone else into wood burning?

I used an oil burner transformer for mine.  Works well and relatively safe.

? Tell me more....  A neon sign transformer is high voltage.
The transformer I'm using is from 1 to 5 volts.

I have made Jacobs ladders using sign transformers.

Kevin you can also use microwave transformers.  Pretty cool stuff. Just google you will see the end product

As I stated above, I used an oil burner transformer.  Cheap to free in northern regions but most importantly only have 20miliamps or so which is a relatively harmless amount.  Not saying it can't throw your heart out of rhythm so try to avoid being shocked, but in most situations you will be fine.

Microwave transformers are another matter.  They typically have amperage levels that will kill you dead and for that reason I wouldn't go near one for this application.  Stick with neon sign or oil burner units.

Ok... This in what I'm using. I think I got real lucky with my junkyard find.
I'm always bringing home thing to take apart just to play with. When i got this
I wasn't sure what it was. It was a wire stripper. From what I can find the
transformer inside is 115 volts primary and from 1 to 5 volts secondary.
Somewhere around 10KVA. I'm using a carbon arc torch for my pen. This is
going to be one BIG wood burning toy. With the low voltage I have no worry
about getting shocked.

My power supply.

My pen.



 (https://forestryforum.com/gallery/albums/userpics/39553/Carbon_arc_torch.jpg?easyrotate_cache=1513621122)

This is 6 inches of #12 ga. wire on setting #2. I'm adding a variac in line with the
power supply for fine voltage adjustment.



 (https://forestryforum.com/gallery/albums/userpics/39553/Hot.JPG?easyrotate_cache=1513621363)

Amp draw from the primary side when turning the wire red is 6.5 amps.

AAW (wood turning association) banned lichtenberg anything cause somebody died.  I think their was more than one.

I made a wood burner from a 12v battery charger.  Used nichrome 16 & 18 gauge wire for my pen.  My battery charger doesn't have enough power for any heavier of wire.  I mostly use it to sign my work, sometimes when I turn a boring bowl I use it to add interest.  Bend the wire to make little designs.  My work is more like hieroglyphics as I don't have the talent for anything else.

I teach informal shop class to several kids.  They really like the wood burning part and give the burner a work out.

I bought one of those carbon arc torches about 30 years ago.  I thought I could braze with it.  One use and it rests in a drawer....ready for the next project. :D

Looked at doing this a while ago, but didn't follow through.  I had a friend do some boards for me, and other random pieces and they looked cool but didn't sell well. A little too abstract.

I did get a call from a guy who wanted me to burn some pieces of maple sticks to make a lightning pattern and sell to him as Harry Potter wands so he could sell them at Cosplay type events.  I never spooled up to do it.

THAT GUY IS USING A MICROWAVE TRANSFORMER THAT CAN KILL YOU QUITE EASILY!!!  That said, I do like his setup  with the clamps and it appears he gets away from the work when it it is energized.  Moving the contact points before the burns connect is a good way to get a large design that you have some control over, but  I don't like the look of the finished product if it goes overboard.  A little goes a long way in my opinion.  To increase conductivity, I use baking soda, about a teaspoon per 16oz of water as my solution.  Let it soak in a bit and not stand on the surface.  The more it soaks or the higher the concentration of baking soda, the deeper the burns. I like the lighter more detailed burns so tend to wipe on wipe off.   DO NOT use salt water as that creates chlorine gas like used in the trenches of WWI.

A neon sign transformer or oil burner ignition transformer puts out sufficient voltage but without the amps, so that is the way I would go.  I have personally been jolted many times over the years by them in a variety of situations and witnessed countless others do the same thing and never any ill effects. That said, whenever you are shocked, tuning  up your snowmobile, electric fence or otherwise, there is always a risk of arrhythmia.  So use caution when working with electricity (duh)

Spent hour or better yesterday watching utubes of this practice. Very interesting!  Saw some neat stuff being created.  One person used a microwave transformer to burn deeper and wider due to higher current.  Then used an oil burner igniter for more veining. 
The creation was a tree.  The trunk and branches were with the microwave.  Then the oil burner was used to create small branches / leaves off the main structure.
Interesting watching the the creation.

I might try this neon sign transformer. It only weights 80lbs.
If I put a variac transformer on the input line I can control the burn.
So it looks like I'm building two machines.

Mind sharing what your set-up looks like?  Got an old burner gun in a shed, might be an interesting thing to do later this winter when I get caught up with my other projects.

Post by: shinnlinger on December 20, 2017, 07:17:56 AM
The only concern I have with that 80lber is that it says it puts out 100 milliamps.  Thats the threshold of "safe" amperage in my mind.   I'm not saying don't do it, but obviously be careful.  Cutting down a tree is dangerous too, but there are more safe ways to do it than others.

I will try to snap a pic today, but all it is is a black box that I added a computer plug to for AC input with a lead attached to each of the two poles.   The video above shows two jumper cable style clips with finish nails or something for probes that he rests on wood blocks.  I soldered some big brass wood screws to the wire leads on mine to use as probes and insulated them with some plastic tubing with the idea you could hold the leads and change the contact points for different burns wearing thick rubber gloves.   I don't do it like that anymore however.  I clamp the leads to the wood and step back and turn it on and then off when I happy with the burn and then reposition as necessary.  Very similar to the video.

It's a little more entailed than just high voltage when you are talking micro waves .High power units are used in induction hardening .They emit super high frequency AC and just like a micro wave oven can cook a person  from the inside out .
At work on the older units they actually used hollow water cooled conductors to the coils which acted much like a wave guide on radar .Everything was shielded but every so often the shielding failed,what a mess that was .I wasn't overly found of working on them for obvious reasons and I know what I'm doing .I personally would stay away from them --just saying

I just have the cheap pen like wood burner, then if I don't like the results it goes into another wood burner for heat.  ;D

No, well I use one once in awhile. I made a large wooden chest from butternut, pine, cherry and birch. The butternut I drew some leaves with the burner, the pine I drew a logging scene in the lid and the pine on the front was a crest. Photos is the gallery and in this forum. Also, a forest scene and a very large purple trillium, which was pretty close to the actual size they grow in my woods. Those two were on a couple wooden serving trays. Again somewhere in my gallery and in this wood working forum.

You guys be careful with those electric gadgets, that stuff can bite.

This is my second picture. I keep working up to a bigger transformer.
It looks like I will be using the biggest one I got. Or maybe I will try
a microwave transformer.

This is the transformer I used to make the picture above.



 (https://forestryforum.com/gallery/albums/userpics/39553/Collage_dump_transformer.JPG?easyrotate_cache=1513810226)

This is the probe that I'm using now. I like it so much better because I can
keep moving it around with out starting and stopping the machine. It was a
welding electrode and I wrapped it with rubber tape for extra protection.
I hold the electrode with my right hand and touch nothing else.



 (https://forestryforum.com/gallery/albums/userpics/39553/Hand_probe.JPG?easyrotate_cache=1513810481)

And last but not least I made this foot pedal that I have to keep my foot on
to keep it turned on. If for some reason I get shocked I think my foot will
leave the pedal. I work at home alone so I want to be safe.

What voltage is on the high side of transformer?   Seems if I got it right from some utubes the oil burner and neon sign ones are 10 to 12 kv with lower current than the microwave transformer that maybe lower voltage and higher current.

I have played with this (microwave transformer) very carefully.  The lower amperage systems are less dangerous but please be careful.  20 milliamps is enough to stop your heart.  Any unit that will make these patterns is capable of killing although some are more likely to do so.

Now all I got to do is to learn to draw. I'm running the power supply on

I was a little disappointed today. I stopped at the junkyard and seen a big
microwave. So I opened it up and took the transformer. From all the videos
I seen on the tube they are the most powerful of all the transformers to use
for fractal burning. Unless I got a bummer somethings wrong. The one I got
wont even spark on the wood. I can get it to spark from wire to wire but
nothing on the wood.

I could not sleep last night thinking about the transformer. From everything
I know about transformers I could not figure out how and why it was working.
Then I looked again. The bottom coil is the primary only. The top coil is the
secondary only with one lead welded to the frame of the transformer. The other
two wires that I'm supposed to cut off is actually a third coil in the middle. Now
I understand how it works. So this transformer would need to be isolated so the
frame does not get grounded. Guess I need to make a plastic box for it.I wonder
what the third coil was used for ?

I'm not all that impressed with the microwave transformer.
I works... But it flares up real easy and it does not give
a good nice looking burn.

I got my smoke hood done and it works great.

After watching the video here with my wife, we wandered through youtube for another hour, just getting a good feel for the process.
Then I went and gutted an old microwave that had a dead LCD screen.
Screwed it to a 1x6 board through 3 rubber feet.  Ran the power leads to the factory power cord and installed a 20A/120V "Momentary On" switch in one of these power leads.
Used an old set of jumper cables (well insulated 10ga wire) and connected one of these to the top coil and one to the base.

1st test last night on a scrap of kiln dried birch went well.   I used a couple of 16p nails as contacts.
I need to grind the clamp teeth down so it grabs the nail more firmly, and I plan to cut the ends off of the board and screw them on as side walls around the transformer and screw an aluminum plate across the top with a hole to mount the switch.  The end result will be a square box with wood base and sides, a metal top, and open ends=power in one end; leads out the other.
No way to touch the trans unless your dumb enough to stick your hand in there.  The switch and machine is placed just past arms reach from the board being burned.  Reach over "Right" and relocate the contacts; lean back "Left" to the switch to activate for several seconds; release switch and repeat.
The beauty of the Momentary on switch and having to let go of it to relocate the contacts, is that I am 100% safe from electrocution with this set up.
Once we get a little practice, I can see using this for accents on slabs, benches, turned bowls and a bunch of other stuff.
Should make some neat accents

Kbeitz,
I'm getting a whole lot less of the deep scoring and a good bit more of the fine little tracks with our MOT
(Microwave Oven Transformer).  It was a pretty powerful Microwave, I think 1200W or 1500W...I'll have to check.

Right now it's giving about half of each type of burn.
I plan to try it with one of the leads on a piece of wet cotton rag as this looks to be a good method of creating finer webs.
Not much smoke yet, but if the water is too pooled up on the surface it does seem to want to flare up more.
Another nice thing about the Momentary On switch is that I can shut it down immediately when it flares up, thereby minimizing the deep trenches.

Got a box of parts from the teardown.  One of my Aviation Electronics teachers told us about using a Magnetron to build a Radar Jammer using a tuned antenna.  Can't recall the details...

Just checked the carcass and it says I've got 13A @120V...so we're running right at 1560W.
Not a weak Microwave.  This one came out of a convenience store when the screen failed, and it got used for another 15years or so.  One of those that will blow up a burrito in less than a minute... :D.

I'm using the HIGH voltage transformer on this one. First I put a grove in the wood
to help guide where I want the arc to go.



 (https://forestryforum.com/gallery/albums/userpics/39553/DSC07622.JPG?easyrotate_cache=1515022757)

Then I wet the grove and hook on the probes and apply power.



 (https://forestryforum.com/gallery/albums/userpics/39553/DSC07630.JPG?easyrotate_cache=1515022868)

Then I move to the next grove...



 (https://forestryforum.com/gallery/albums/userpics/39553/DSC07634.JPG?easyrotate_cache=1515022942)

Let the fire fly....

Touching up...



 (https://forestryforum.com/gallery/albums/userpics/39553/DSC07637.JPG?easyrotate_cache=1515023257)

Guys,

Please don't think of me as a safety Nancy.   I'm all for safety, but I don't go around preaching to the choir.

A friend of mine is dead because of this process.  I don't know exactly what happened, and it doesn't matter.  He's gone, and left behind a wife and 2 small kids.

Please be careful during your experimentations.

All I got. Don't flame me for caring......

An artist is his own biggest critic and will never be completly satisfied. The secret is to learn when to say good enough and move on. When I was painting, I couldn't stand to have finished paintings around as they would torment me. I've been away from it long enough now that when I see one of my paintings hanging somewhere, it doesn't bother me.
As much. ;)

unit.

Burnmaster.

Homemade unit. It's so very much faster.
