[pianotech] upside down CA job report

[James Johnson]

I removed the action and the music rack, then the lid.  With the lid gone we could roll the piano over on the straight side (after checking the lyre for stability and removing the left front leg) using the lyre as the pivot point.  We left the lyre and two legs on the piano.  We then rolled it all the way over letting it rest on some padded 2X4s on top of a plastic tarp (just in case some of the CA glue escaped).  The customer and one of his drinking buddies helped me flip it over.  The difficult part was laying down on my side and working in the action cavity.  The CA fumes were very concentrated in that small space and even though I had a fan blowing directly on the work, it was still very strong.  Next time I will use a more powerful respirator and some sealed goggles (the type they make for chopping onions will probably work).  Also perhaps some sort of vacuum system to suck the fumes outdoors.

  Thanks for the update. It is always good to hear the results of a rather unorthodox repair. My big questions, and/or concern, is how did you flip the piano over and back? You probably told us about that 6 months ago, but I forgot.

  About 6 months ago I shared my experience of treating a grand pin block from the bottom with the piano upside down.  I had previously treated it from the top, but because of the plate bushings, I didn't get good enough penetration to make much of a difference.
  Anyway, today I returned to do the 6 month tuning and I'm happy to report that the piano is holding well and all the pins feel quite good.  If I didn't know that the pin block had been treated, I probably wouldn't have noticed that the pins felt different than any other older piano.  I would definately consider using this technique again if circumstances warranted it.  The piano, a Harrington grand, was not worth doing any major rebuilding, nor could the customer have afforded it anyway.  This process saved the piano for what I hope will be a number of years, and for this customer's use, it worked out well.
