Home made wood burning tool. pyrography

That is cool looking. It is easy enoughto see you guys know much more about electricity than I do, so all I can say is play safe.

[Al_Smith]

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

UNNESSESARY QUOTE REMOVED!!!!

The  high frequency does not come from the transformer it comes
from the magnetron.

[Kbeitz]

Are you holding the probes to get the design?

On that first one no... I let the plastic parts sit on the wood and I plugged
and unplugged the transformer each time I moved the plastic parts.
I'll post the next pictures in the next post of what I'm doing now.

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.



 

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.



 

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.

I wonder if this should be moved to the full membership board so no children see it and try it. Pretty easy for a spark to crawl without the proper materials.

Check out U-tube. 100's of videos on how to do this...
Not much different than carving with a chain saw...

Third one... This was done with my biggest transformer.
everything was done on Pine. Tomorrow I'm going to try some oak.

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.

12 kv

You using baking soda and water brushed on the wood?

Almost... Washing soda made by the baking soda co.
It's stuff I use for cleaning rusted metals.  Electrolysis
Today I'm going to try baking soda to see if there is a difference.

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.

[SlowJoeCrow]

Looks nice K!

[Kbeitz]

Not to bad for a all home made unit. I could not wait until my Nichrome
resistance wire got here so I used some music wire. Seemed to work good.
Now all I got to do is to learn to draw. I'm running the power supply on
number 1. It goes up to 5. Lots of power.

I use one of those cheap combination woodburners/soldering irons.

Wow... That was 10 years ago...
I finished all 10 pages.
Now if only I could get as good as you...
Great looking work...

Edit....

I just went back and finished the other 6 pages... You got  talent...

[Kbeitz]

Practice Practice Practice...

Fun ain't it!  Shop class with uncle Larry.



With the nichrome wire you can thin it out on a anvil to make smaller lines.

Just look at that smile...

I'm putting in a smoke extractor today....



 

[Jeff]

You already have a prototype  ;) ;) ;)

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.



 

[Kbeitz]

My bad.... I had it wired wrong. The bottom coil does not even get used.
Video says to cut off the bottom wires and use the one wire off the top
coil and one wire from the base. I went back to the shop and tried it...
Yep it worked... Hot Dog...
