Restrining after doping

[Will Wickham]

Hi Robin,

I have a Kranich and Bach grand that was doped many many years ago,  
probably at least 15-20 years before I got it.. I purchased/inherited  
the piano from a somewhat distant relative prior to becoming a piano  
tech myself. The technician who worked on it for me all those years  
ago only re-pinned the ones that absolutely wouldn't hold and in the  
25+ years since I have not replaced a single pin. The only drawback  
I've experienced thus far is the pins that were the 'dopiest' are  
jumpy and therefor somewhat hard to zero in on the correct pitch when  
tuning. They all hold very well though.

Having said all of this, if I were faced with the same situation now  
at a customers house, I would likely try CA first then consider  
plugging and re-drilling for new pins or replacing the entire block.
