[pianotech] CA pinblock with tight bushings?

[Mike Spalding]

List,

During a recent thread on CA for pinblocks, someone mentioned the idea 
of drilling a small hole down through each bushing to improve the flow 
of CA to the block.  I believe this person had not tried it yet, but was 
considering it.  I have a situation (newish Asian grand, tight bushings, 
loose block) where this might be the only way to get the CA where it 
belongs.  Has anyone tried this technique, and if so, with what results?

thanks

Mike
