John, been away for a few days. I always start by following an existing crack that crosses the center of the log. I open this up with an ax pounded in with a sledge, then start wedges in the side of the log and keep working them till it falls in half. Sometimes will have to use a hatchet to cut through the stringy pieces that don't want to let go. Once in half I decide how many splits will give me the best staves to miss knots and other problem areas. I start the ax in the end again and follow the steps described to get it in half. The laggest tree so far has been 15" at the stump end, most are smaller 6-8" stuff. Maybe I've just been lucky with the few that I have done so far, but I didn't think it was very hard to split.
