Mike - I recently built a 24'x36' timber frame barn from green hemlock from the southern tier. Its main problem is that is prone to shake. I had a good batch in which only 3 beams out of 90 beams total showed the problem. The frame has been up for 18 months and so far has shown only minor movement. It works very easily green and is progressively harder to work as it dries. Good luck with your project. jekbear
