<!doctype html public "-//w3c//dtd html 4.0 transitional//en"> <html> Hazen, One problem I've had was knowing how much CA to use, and I'm still not sure.  At a convention a guy said in a mini-technical presentation that four drops for each tuning pin is enough.  I've also heard of those who use three or four (2 ounce) bottles.  That's a lot of variation! So my results have been mixed, depending on whose advice I followed.  At the present time I am using one bottle, sometimes a little less.  I've begun keeping better records at which pianos get how much, so I can compare results more intelligently.  As of now it seems that one bottle is sufficient.  I also suspect that the success depends somewhat on the presence of gaps in the bushing surrounding the tuning pin.  If things appear very tight there, CA would have greater difficulty getting to where it can do the most good. While I have had success in the past with Garfield's, I don't use it anymore. I had a better quality grand piano, 27 years old, with loose tuning pins.  I really did not want to introduce any substance into the pinblock, so I tried tapping a few pins deeper, just enough so they moved.  That worked wonders.  I cannot detect anything in the feel while tuning that would indicate there had ever been a problem.
