Hi, Greg

I'm guessing here -- I leave this kind of major surgery to other folks -- 
but I wonder if it could be hung up on fragments of your hide glue which 
cracked off when the joint failed? Maybe if you inserted some steam or very 
hot water, and then tried to pull it tight?

Failing that, if you have real confidence in the security of your bolts, 
perhaps you could lay  a bead of slow-set epoxy along the crack, and then 
thin it down with a heat gun until it got sucked into the seam, repeating 
until it is filled. It doesn't look like a gaping chasm, thank heavens.
