Fractal Burner

Original burn was gorgeous, then I tried to do the other side and it was too wet and burned through and ruined it. Planed it down and redid it with much less electrolyte and also made sure the surface below it was dry.

The grain structure of red cedar seems to work really well for fractal burning.

That looks great.

One thought, if you let it burn as long as it wants will it keep going and fine other avenues of travel? Blacken the whole board?

I haven't left it on long enough to really know, but I don't think so. Typically it sort of peters out on it's own unless you shut it off and add more electrolyte. Even then, further burning seems limited.

The other factor is that once it burns a path from electrode to electrode, it tends to just deepen that patch and start a real smudge.

How deep are the main burn lines? I was thinking on some plain looking bowls that this would really set them apart but, if the main burn lines are too deep, it might just make a mess. Any way to control the amount of juice to the electrodes? Inquiring minds and all.

I tried aromatic red cedar, oak, pine, fir, mahogany and birch veneer plywood.

The red cedar seems to burn the most consistently and spread the pattern out more rather than a deep single pass.

Birch veneer plywood works well too.

Fir wasn't too impressive, but I also tried screwing the screws into the end grain rather than on the top so that may have been a factor.

Mahogany was iffy, but the piece I grabbed out of the scrap bin had a crack in it and the burn mainly followed the crack.

Oak was probably the least attractive result.

I've got some teak to try yet.

One thing I want to try to do is burn some long, narrow pieces with an eye toward making picture frames out of them. The distance between electrodes definitely affects the burn, I may have to do them in sections.

As far as depth, most of it is pretty shallow. It seems to depend on the grain structure of the wood. If there's a wide streak of sapwood, it'll follow that and burn it until you turn it off. Path of least resistance and all that.

One thing I've seen on Ewe Toob that I want to try, especially with burns that go deep, is filling it all with tinted epoxy. I've seen some really spectacular samples of that.

On bowls, I'd think you'd want your first attempt to be on something all out of one type of wood. I'm also thinking it may not cross glue lines, at least not without help. Be interesting to try some different approaches and see if it works.

Thank you for the update. Yeah, I was thinking of bowls from one piece of wood. I have a couple maple that are nice bowls but, not much pop because the grain is just plain. Also have a black walnut bowl that is all sap wood, Beautiful but, not something that will wow a perspective customer. Either discount it to sell it or, add something to make it more "wow".

Been thinking about the bowl thing.

If you turn a bowl out of a solid chunk of wood like a piece of a log, you're carving away the end grain and the normal grain of the wood would run from top to bottom, right?

So you'd have to put one electrode say in the center of the bottom and then do multiple burns moving the other electrode around the rim.

Just thinking out loud here, I'd leave the bowl a little taller than finished height so I could drill small holes around the lip to insert a screw or nail to clip the electrode to. Probably start with 4 equally spaced and just treat a quarter of the bowl at a time with electrolyte.

Burn that section, set it aside to dry, then move the electrode, dope another quarter and burn it, etc.

I think that'd be interesting to try.

If the grain runs across the bowl, it'd be a whole other ball game.

Wow, that's impressive. I don't think I've ever seen anything like that for sale before.

Actually, most bowls are turned with the grain running the other way. You can turn a limb down the way you have it drawn but, most of the time turners avoid the "pith" or heart of the log as that tends to split. In the video you posted of the guy burning the bowl, you can see the grain running across the bowl.

Thanks for that video. Hadn't seen that one.
