David, Apply liberally. You don't want glue flowing all over, but neither just one or two drops. As mentioned earlier, there is no need to get excessive, but I think the only concern is where the glue really is going; and as discussed before, if you seem to be using too much and the pins keep drinking, let the first treatment dry and apply more later if needed. Truly can't imaging CA actually causing a pin to break. I don't question the experience, only the mechanism. Probably a bad pin, now it's actually tight again, and - SNAP!! I would not blame the CA. Typically CA makes an instrument tunable again, sometimes makes pins actually tight again, but not in the "Brand-New Baldwin" category. Regards, William R.

One drop per tuning pin? Two drops per tuning pin? Can't say as I'll ever need to do this repair...but, I sure as heck don't want any t-pins snapping off...yikes. The only time I've used CA is on a bass tuning pin that wouldn't hold any tension and then I removed and swabbed the hole. Thinking back I might as well of put in a larger pin...!!!
