I've tried measuring sticks, stuff that clamps to the saw, lumber crayons, tape measures, and who knows what else. I came to the conclusion that it's faster, easier, and simpler to just mark it on the saw. I cut everything 21~23" long, and I know where that hits on my saws. Yeah, I have to turn it sideways every time, but it's already in my hands, I don't have anything extra sticking out getting caught on stuff as I'm moving, I don't have to carry extra crap with me, and I only have to make on trip down the tree. A lot of guys I know consider it anal retentive to try to measure your firewood somehow, and they just eyeball it. I stay about 4 years a head on my cutting, and I like how well the wood stacks when it's consisistant. I hate having to restack it if it fall over :msp_angry:
Just my 2 bits,
Mark
