Thanks Don, as usual you are a wealth of helpful information.

Unfortunately for me, the two tree species I have most abundantly are pignut hickory and maple, both of which are very susceptible to rot. That is one of the reasons I have decided to seal all timbers on outside walls with wood tar, and to seal the boarding gaps as well (makes the whole things kind of like a Klinker built boat). The other reasons being it is authentic, and it looks and smells wonderful.

Was de eine ilüchtet isch für angeri villech nid so klar.
