They've started selling these small bonfire logs in my area.
The log looks like Birch.

I can't figure how they made the star cut into the log. Its not with a chainsaw, its to perfect.

However they did it, this is a hot item right now and these small bonfire logs are selling!

How deep are they? It looks like probably a morticer may have done it, or maybe a router.

Maybe even just setting a skil saw down on the log. With that wide of a cut, they may have a shim under the blade to make it wobble and give a bigger cut.

The cut goes down about 1/3 of the way.
I'm pretty sure I can do it with a chainsaw but these cuts look perfect.

I looked at the website for more info.  Nothing about manufacturing.  Amazingly, its patent pending.  A log with a unique sawcut say_what materhead

Watching your video, I'm wondering if the center has been soaked in some type of oil?

May just have some wax poured in the cuts.

I looked at those recently. The one I looked at it was a chainsaw cut, but I'm sure it was machine guided. I think those are originally known as Swedish candles, and have been around a long time. You can make your own in a few seconds with a chainsaw. Normally, the cuts would go down the sides almost to the bottom. Some wax or other fuel is often poured in the middle to get it burning.

Maybe a good technique to try for burning out stumps.

Depth a third of the way, would put them at about 4" ??

Get one and split it open so we can see the bottom of the cut and how it may have been made.  ;)

If I was going to make a heap I'd be mating up an electric chainsaw and a drill press, with a rotating table to clamp and index the log.

I would bet on a morticer machine they use for mortises in timberframing. Makita makes them as well as others. They are pretty pricey.

Go to you tube and type in" chain mortise tips" Jim Rodgers has a video of using one. I know it is on a beam, but you could probably keep turning it.

I thought about that Ian.....but would the chain still kick?

As Dave says, these are Swedish candles. There is no need to cut them like that, you can cut down over the whole radius. They are very popular here in The Netherlands and sell for about $ 5 (60 for $ 300  :) ) I saw them as little presents and use red pine with a lot of resin. The jig I made works OK, but needs some modification in grabbing the log with the spikes.

Roghair, do you put any kind of burning oil in the cracks?

Would it be easier to saw the grooves while its still a log and after the grooves are sawn, saw off a 16" length or whatever short log?

I drill a hole for a firelighter, most of the time that works fine. The grooves give a good ventilation (venturi), which might be less with the cut you were asking for in your OP. They probably use some kind of oil.

I am not very good with the CS, so for me it would be more difficult making these cuts in an horizontal log. As you can see in the picture, cutting it square from the log is also a challenge...

Another name I've seen is Stump Stove. As I recall the cuts were criss crossed and a hole for air flow bored in the bottom.

Maybe they used a morticer with a slotting chain attachment?


 
Anything someone can design, I can sure figure out how to fix!
If I say it\\\\\\\'s going to take so long, multiply that by at least 3!

First time I've seen one of these Brad. Of course I've never seen a sow blower.  :D

Thanks of the pic. I think this is what Ian may have been talking about.
