Separting ribs on an upright

[J W Stein]

Okay,

Here's a question for the group.  Every now and again I come across upright 
pianos where one to several of the ribs are starting to separate from 
soundboard.  Is there any easy way to solve this problem other than rigging 
a clamping system.  If not, is there an easy clamping system?  I prefer not 
using screws as a clamp.

Thanks,

Jon
