<HTML>I have successfully used thin (red label) CA on a Broadwood with the plate threaded to the tuning pins. --without turning the piano over.  First, I had to remove the cloth punching under the tuning pin coil, as it would wick up the CA rather than letting it through.  I can't remember whether I made more than one pass over the pins with the CA.  I was warned NOT to use accelerator.  I've been back twice to tune the piano, and it is holding well.  Time will tell whether this is just a band-aid treatment.
