back problems

[Greg Newell]

Joe,
         I understand and agree with your example except that I'm not so 
sure that my circumstance fits it. If it is keeping the joint apart why am 
I able to close it with the clamp but not the screws/bolts? I'm thinking 
that I just don't have a screw/bolt in the right place to exert pressure 
where it's needed. That's why I'm wondering if drilling into a clear spot 
in the plate raised edge is a wise idea. It would certainly be in the right 
place to exert pressure where it is needed then. There is no other place to 
drill without tuning pin obstruction.

best,
Greg
