I'm not fully calibrated yet so I don't trust my ability to eyeball where to make cuts when bucking. I don't want that wand thing hanging off the side of my chainsaw either. I like cutting 17" lengths as I found I can only get one 18" into my stove - the others have to be a bit shorter. So how do you measure, if you measure? I see a "Mingo" on eBay but would like to make something cheaper. Currently I use a 17" stick and a can of spray paint to measure and mark the whole tree.
