I know climate impacts the life of a Nano's shell, but could the fluctuation of temps (from cutting the unit on/off) cause it to crack as well? I have a friend who has left his walnut unit running at 6.5 since it arrived at his home (Fall of 2016) and he has not had any issues. My shell was replaced within 6mo of use (I got mine a week before he bought his) and I cut it on/off daily. I also treated the wood weekly prior to it cracking, where he has never put anything on his. Now, excuse me as I partake in a few rips of some Gorilla Glue and enjoy this lazy Sunday! Edited to try and add an image . Doesn't seem to be working correctly. Is it Imgur or user error? Figured it out!
