general wet to dry expansion is around 1% along the grain, 3%
tangentially roundn the trunk and 5% radially

But if constrained it should be OK.

This is what I am concerned about, at 1.4m 1% means a possible movement of 14 mm with one end pressing against the house wall and the other end pressing against the garage wall. Do I allow for this movement or will the walls constrain it perhaps causing the beam to flex slightly?
