HehHeh . . . I don't have the patience to be that exact when it comes to bucking wood. I generally eye-ball it or may use the saw's bar as a rough guide and then mark the tree with the saw's chain like Tony to give me an idea of where I will cut.
My figuring is that as long as the wood fits in the stovebox it's good . . . I'm not trying to win any firewood beauty contests . . . generally the wood ends up around the same size. Occasionally some wood is longer and needs to be zinged down to size (typically before I load it in the woodshed) . . . and occasionally when I'm working with my buddy Joe the wood is a bit smaller than I like (because my buddy has a smaller sized woodstove and tends to cut smaller even when we're working on a load for me -- but who am I to complain when I'm getting free labor?)
