Cam I usually start with a hatchet at the end driven into the but of the log then a lag bolt just past the end of the blade and then every three or four inches or so. then a wedge between the bolts. Don't rush give the wood time to smap cracle and pop. them more bolts, then more beer. Before you know it you can start cutting the fibres to seperate the halves. Quarters can usually be done with wedges unless the log is really large. Ron
