I have an old and sick Black Locust tree in my yard that I am having put down by a tree service. The truck is about 20' high and 5' in diameter. I ask the tree service guy to leave all the limbs 2" and bigger so I could cut them up into firewood lengths myself. He will chip the fine material. The problem I have is what to do with the trunk. I do not have a splitter, (only a maul) and do not have access to one. The tree guy said he could cut the trunk into 14" cookies for me and leave them, or he could take them. I would very much like him to leave them, but I need to know how I can, if possible, cut up 5' diameter Locust cookies with a MS29. Is is doable? How might it be done? Again a hydraulic or electric splitter is not an option, either is a bigger saw. I have a 8lb maul and a MS290 with a 20" bar. Any suggestions would be most appreciated! FYI - I have no experience at all with Locust. I have been cutting and burning softwoods pine/fir/spruce exclusively for years.
