Decided to try my luck at free hand chainsaw slabbing with a piece of cottonwood that stands somewhere between 4 and 5 feet high. I used a 20" bar on the saw with a chain I'd sharpened to 5 degrees for ripping instead of crosscutting. As you can see from this photo, the 20" bar didn't even come close to going all the way through the log:
I'll post some photos of the slabs once I'm done. These old bones of mine just do NOT seem to want to cooperate as much now as they did when I was younger!
