Hello,
Because examples exist of the use of 20 + inch diameter trees in various constructions says nothing of whether these trees are appropriate for any particular project. Before you get into handling the trees in question maybe it is an idea to sort out just what they will be used for exactly and if or not these are appropriate for that use. There is evidence here that such trees have been used in large barn construction and evidence that large trees have been used in log constructions. I can see obvious rationale in both of these cases relating to use and scale and efficiency. "Because I have them" and "various demands" don't seem so convincing. I have hewn and used oversized trees for clear reason and also for no other reason than that they were at hand and in the later case I regretted the waste and the amateurishness - in the bad sense of that word - of the endeavor.
Greetings,
Don Wagstaff
