Good point Jo, yes, a wheelbarrow would make very good sense. I did not know the chainsaw setup was an old idea. It seems too many YouTube videos are made by some enthusiastic person the moment they finished the project.
I like this idea though, very easy to set up beside a cord wood pile, keeps the work more in a standing position, and the saw away from mud and rocks, etc.
I will modify the base to have 3 raised feet, the one they show isn’t made to work on rough ground or in the bush.
