I recently saw a 1927 grand that was too loose to tune, but would be a ideal candidate for a superglue pinblock treatment. I did 6 or 7 superglue treatments to blocks, all but one worked very well, and my experience tells me that it should work on this piano extremely well. It was previously pinblock treated with traditional method decades ago, pins are only tapped half way in, solid block, no pin bushings, marginal torque of 10 to 20+ in./lbs., --NOT negative torque, a "dry" feel to the pins, not a greasy or gummy feel. Rebuilding is out of the question. ($) I am so allergic to the superglue ( cyanoacrylates) now that I have had severe breathing problems for days after exposure. I cannot even consider doing this job, and would like to recommend someone else to the customer. If you work in Phoenix ( the piano is in Cave Creek) and would consider doing this "acrylic" pinblock treatment, e-mail me or telephone me and let me know. Bill Simon 623-581-1748
