I use CA maybe 5 times @ year...been doing this for 15 years... What helps tremendously, if the CA doesn't do the trick, is to tap in the pins...just a little bit...a small amount of depth increase does a disproportionally amount of good... Really...try it....knocking them down to the plate is not necessary to increase the tightness...Ron will probably tell us why.... Also, I found a way to keep from frying the brain cells during CA application.... Bring a piano quilt or big towel, and cover the section you have just finished, while doing the next section...CA fumes are REALLY bad on the body...Don't tough-it out... Save your breathing apparatus for more important things, like getting oxygen into the blood....
