Dear Tony

This is my mental vision of a vertical burning log:

[Tenkara USA * View topic - Swedish log fire/candle]

All those cutes are made with a chainsaw and from what I see, they are pretty deep - not something that can be made by hand or easily.

As to the practicality of such a "stove" I am dubious.  For one thing control of the firepower seems impossible - perhaps a pot skirt?

Another approach is this:

[swedish log candle - Rustical]

It appears that the lower cuts were widened with the chainsaw.

This one was split and then reassembled.  They called this a Canadian Candle.
["Swedish Torch" or "Canadian Candle". | Swedish fire log, Camping stove ...]

You can see the little wedge shoved into the gap on the left. I can do this easily with a log splitter because the natural tendency is to create a set of pie/wedge shapes.

What such a fire would be useful for is baking bread.

Regards
Crispin

Crispin, where possible I have responded to your comments.

Is there a hole in the middle of the tree?  Sometimes?
Whether there is a hole in the middle I do not know as I have not seen a clear cross-section of a dead or green coconut palm trunk. Palm trunks I have seen have been green and there is no centre hole. As they dry a hole may develop but I don't know.

Is it soft in the centre?
 Again as for how soft the centre is I do not know. Even if they are not the wood is fibrous enough to allow for a partial hole to be made. I am thinking the whole thing is fibrous enough to not need a whole all the way through and air would flow OK.

What I understand about the "candle" is that the wood has to be really dry. True?
Yes, really dry. The Sweedish Candles sold in Australia seem almost kiln dried. Not sure if they are imported, but if they were they would be kiln heat treated to allow them to be imported to comply with BioSecurity regulations.

Next, is a palm trunk dry? Is it a sponge?
The split trunks I saw were very dry. Old and sun-dried. A green palm seems spongey, but the split wood was just dry and fibrous. Many of the dead coconut palms I saw had been struck by lightening. I guess they could be dry but I can't imagine all of them had been hit.

Is it suitable for creating the vertical cuts of the candle using a bush knife?  Maybe the cuts could be vee-shaped.
Not sure there is a need for this. The texture reminds me of the old cigarette commercials showing burning tobacco inside the cigarette paper. Maybe an SSM jet flame underneath could be good??

All the ones I have seen were cut with a chainsaw.
The best thing would be to have a chainsaw cut. In the area where I was there were chainsaws cutting up other hard wood, good building timber and twisted gnarly trees, so slicing up a coconut palm would be pretty easy.

Maybe someone on the list has some clearer answers to your questions or better still able to give it a try. I will see if I can get through to someone in Haku for them to give it a try. The biggest issue I see is getting air in underneath. They are not great at cleaning out fireplaces.

Regards,

Tony Blake
