A good local buddy that I met through BUSA lent me his copy of Mors Kochansky's BushCraft. It is a great read and I started browsing through the fire section which provided cartoon descriptions of different set ups like the standard single hole with notch, split stick, natural V method and the two hole method.

I've tried the split stick a couple of times and haven't yet had success at it. Seeing the last cartoon on the two hole method my eye was attracted to a little bit of italics script in the cartoon saying 'This method is the best one of all'. Well, I was intrigued to figure out why Mors likes this one so much and I just had to try it.

In the two hole method, you drill out two holes in your hearth next to one another. The holes can either intersect at their edges or you can drill a little channel between the two of them. You are supposed to drill out the holes pretty deep, about 2 cm. The ember forms in between the holes or in the second hole as you are drilling.

It was a lot of effort drilling. I actually blew through a drill and had to get a second drill to complete the job. Had I been using the standard hole with notch in the side, I would have finished a coal much faster.

This was the last bit of drill out before I achieved success.

Here is the ember. It formed right in the center channel between the holes.

Pleased with my success, I blew that ember into flame using jute twin as a tinder nest and started up a fire that lit up my BBQ coals for cooking dinner.

On tonights menu was Chinook salmon and chicken breast. The salmon was marinated with soy sauce and the chicken with a balsamic vinegrette.

So why the two hole method? As I see it, the chief advantage is the ability to form the ember on top of your hearth wood. This can circumvent problems when the ground is wet and you can't find something suitable to put under your hearth when using the standard single hole with notch technique.

The disadvantage to the two stick method is that there is more processing to split your hearth and you need to drill out two holes which requires a lot of drilling. Might be a good idea to consider using a harder drill to facilitate the drilling and then switch to your normal drill to get an ember. The advantage over the two stick method is that you are accessing the interior of the wood which is likely to be more dry than drilling through the bark as you would do on the two stick.
 
Good Stuff, Ken you are becoming a real friction fire guru..... I've been meaning to try that method but haven;t gotten around to it yet...
Great original thread... Well done.. Thanks for posting.
 
Nice, I will have to try that. Just getting use to the two stick method. Which woods did you use?
 
Neat! I hadn't seen the two hole method before. And your experience with drilling out the two holes... have you tried a stone (flint) drill for that? I've been thinking of making replaceable foreshafts for my drill and it wouldn't be hard to include one with a flint drill bit. :thumbup:

That's a really neat idea Codger. Part of the pain in this technique is boring through the wood. I thought about it after the fact, that using a hard drill for the initial drilling would make this go much easier.
 
Here is an example of a flint drill bit stuck in a piece of river cane:

I watched a couple of youtube videos of Masai tribesmen making fire with a hand drill. They set their fireboard on a machete blade to catch the dust and coal.

Would it work to notch the fireboard to catch the coal like this?

Wow! I thought I had seen them all. Thanks for sharing this. I keep meaning to get that book but haven't seen it in a bookstore around here, so I haven't picked it up.

Yes, that would be more like the standard one hole with notch in the side technique. The only issue would the extra degree of carving needed to shape your piece like that. However it should work plenty fine.
 
Thanks for that KGD. This is the first time I've come across that method. Might be quicker to prepare a two-hole hearth than a notched one. Must try it.
