Pinblock CA after Dope?

[Marcel Carey]

Ah...

I've found pianos with tuning pins thighter in the plate bushings than
in the block. This is a situation that I saw on a Korean grand of about
15 years ago. How did I find this out, is when I had to replace a
string, I wanted to replace the pins since it was loose. Well, the
bushings came out with the pins, and, as soon as the bushings were out
of the plate, I could feel the pins very loose in the block. This is why
CA has not worked for me in SOME situations. Whenever there were no
plate bushings, it worked all the time.
