CA Glue for pin blocks

[Fenton Murray]

Jonathan,
IMO if a piano will not stay in tune because of loose pins, re-stringing with out a new block would not be a wise move. In other words, you've got nothing to loose by trying some CA. The only time I would re-string an old block would be if the torque on the original pins was still good.

  Thank you to everyone for sharing your experience.  My concern is not so much whether it will work but rather whether will it destroy a good pin block.  I've seen too many pin blocks ruined by Pin Tite.  I guess my question is, if it doesn't work can I still go ahead and re-pin?

    What consistency of CA do we find works the best?

      Hi Alicia

      You should expand your sample. I bet for every tech you could come up with that had disastrous results there are several dozen with excellent results. My personal results with CA have been excellent.

      On the other hand, my personal results with Pin Tite have been hugely disappointing. I found it to only work in 50% of the cases and in many of those cases only for 2-4 years. You also find the old grands with severely stained pin fields showing many applications of dope over the years. Those pianos typically have very spongy pins and will respond very poorly to pin tite treatment. They will, however, respond with excellent results to CA treatment.

      I suggest you try it! You’ll like it! J

      2 oz apply with hypo oiler.

      Johnathan, 
       
      Not you're not repeating yourself...
      I've never used CA glue on tuning pinns and wouldn't recoomend doing so.. I know a technician who has with disasterous results. I use "Pin Tite" myself to chemically treat pinblocks, and I must say it does wonders. It's about $25-30 a bottle of 8oz and lasts for a few pianos. I have crossed a Wurlitzer recently the owner told me that a technician used CA on it a bit while ago, after trying to set the temperament I fully refused to tune the piano, pins were jumping and every blow i gave a key, pin slipped...

      I'm new to this list and I'm not sure if I sent this before I was actually signed up.  So I hope I'm not repeating myself.  Has anybody had any experience using CA glue on pin blocks and subsequently restringing?  How do the pins feel after a treatment?  Do they jump? How long does it last? And if they do start losing their hold after a few years, or if the job turns out to be one of the 10% that doesn't work, can one still go back to simply restringing?

      Thanks
