back problems

[Greg Newell]

Susan,
         Thanks for the response! I'm not sure what to think about your 
glue fragment theory. It seems that the fragments would simply crush into 
to wood as the new washers on the back did. Still, I'm not sure. That glue 
does dry / cure pretty dog gone hard. If the wood were dense enough I 
suppose it could be holding the joint apart. OTOH I am able to close the 
gap with a "C" clamp, I just can't keep it closed with the position of the 
bolts. Perhaps a light misting of water and some gorilla glue?

best,
Greg
