To date, I’ve not = found one instance where it would not work. Usually I only use ˝ to ž of a 2 = oz bottle, using a hypo oiler to apply. This gives very good control. Occasionally, = 2 or 3 pins may need re-treated. In one extreme case, I removed the pin, = squirted CA glue down the hole and replaced the pin. Worked wonderfully. I am = convinced it works by swelling and setting the wood, not by bonding the pin to the = wood or filling gaps with glue. This is why it continues to work years after its application and multiple tunings that would otherwise destroy the = joint.<o:p></o:p> <!= [if = !supportEmptyParas]> <![endif]><o:p></o:p> 2 = bottles of glue is way overkill from my experience, if you are using 2 oz = bottles. <o:p></o:p> <!= [if = !supportEmptyParas]> <![endif]><o:p></o:p> Fo= r a very quick fix (on junk spinets that are otherwise destined for scrap), it is possible to apply without laying the piano down. Just apply to the base = of the pin with the hypo oiler and it goes in. Be very careful not to apply too = much so that it runs down the strings onto the damper felts.

Dozens of pins = were so loose that they immediately spun back on their own = after raising the pitch. I tipped the piano back and applied two bottles = of thin CA (after spending 20 minutes trying to talk the lady into dumping the = piano). It was quite apparent that the pins had been doped some years ago - = plate was all stained at the tuning pins and the feel of the few pins that had any = torque was very spongy. The CA treatment seems to work well a couple days later = when I pitch-raised and tuned the piano.<o:p></o:p><= /p>  <o:p></o:p><= /p> I went back there last night to tune. Three pins had let go.
