thats what I posted. make a series of cuts from top to near bottom, stuff a gas infuzed hunk of paper or what have you down the center and light it.
I ended up making that one and giving it to my helper, he burned it this summer when he went camping and said it worked fine.
I think it was the Brits that showed it here first, from an outdoor jobsite they were cooking lunch up on one.
two more pics I found on my hard drive, these arent ones I made.
Or, do it the natural way...this was the first one I ever did...it was slightly hollow with a very small hole at top where I had cut it (about quarter sized)...hollow at bottom was about 5-6 inches. There was a natural opening at the bottom on the side where I could feed small pieces of wood.
The log on the left is the firelog. I am feeding small pieces of fat lightard into it (heavily resin-ed pine) and the resulting flames are pretty impressive.
