Andy BB,
Thanks for the link. I like the idea of using the small diameter limb bundle very much. If I can escape hard manual labor, I'm all for it! I do see a couple of potential problems with this type of fire log however. First off, anyone using this method will be attempting to build a fire in among the small logs and as a consequence, the kindling will have to ignite the bark first, and the inner log later. Most barks don't really burn very well. At least until a fairly large amount of heat is present. The other problem involves wet wood. The bundle of small limbs will (if raining) be wet, so it will be even harder to light. A larger split log will, of course be bone dry on the inside, where the fire is going to be built, even if it is soaking wet on the outside. This set up will burn quicker, longer, and hotter with more flame and heat.
I like both of these techniques, and wouldn't say one was better than the other. The best thing is that each of them can be used depending on the situation and the availability (or lack) of saws and axes. I think if I was going to build a bundle fire, and If I had a hatchet, I would quickly knock the bark off of three or four of the logs prior to making the bundle and I would put them in the center and build my fire in the center of the de-barked logs. This would, in most cases, do away with any wet wood and hard to light bark, and would take very little effort.
