The one thing that I would like to ask about drilling through and putting a 
bolt through the tree is,  if the bolt is coated with a  metal could the 
metal be toxic to the tree?  Copper nails can do great damage to trees.  I 
am wondering if cadmium is used for the plating whether it would be 
toxic?  Maybe a sheath or tube of inert plastic around the bolt would be a 
safety idea?  I donot know, maybe someone has some experince or knowledge.
