https://www.hearth.com/talk/threads/it-pays-to-ask-part-2.106699/#post-1393412 See the linked post for reference - I went back to tackle the large black locust trunk that I had left at the scrounge site back in Feb/Mar of this year. I had left it because the size was intimidating and there was much easier stuff to get. I just recently took a look and it was still setting there. I haven't gotten the chance to do any cutting for months, so I decided to go back for it. This was easily the largest trunk I've ever attempted, I'm guessing about 36" in the widest direction. That's an 18" bar. It didn't go quickly (understatement), but the little saw made it through just fine. Luckily, I managed to avoid pinching the bar with some wooden wedges that I cut at the site. I'll really only end up with about 4 rounds similar to the pic below: I still haven't hauled it back home. It will have to be split at least in quarters for me to manage getting it into the wheelbarrow, across the field & into the trailer. I will add this to the ~1.5 cord of locust that I got from this same tree last winter - which will all end up being for somewhere around 2017-18.
