[pianotech] Spam: Downbearing

I agree with Dean on the CA glue. I use a Qtip. Put the CA glue in a small medicine cup, dip the Qtip for each hole and run it up and down the hole, then restring. Amazing how well it works. If the pinblock has cracks, you might want to go with the plugging as Dean also suggested.

  I'd urge you to rethink the  pinblock. Use pin block plugs from Web Phillips. Very easy. The odds are not good that re-pinning an old upright will hold. And if it doesn't your reputation is tarnished as a result. If you do choose to repin only, add 2-3 drops of thin CA glue into the holes before inserting the new pins. It will dramatically improve their gripping power.

        I am coming up on my first rebuild/restoration. Probably won't install new pinblock, but I am interested in measuring Downbearing, not only on this upright but also in general. It seems like an interesting thing at the moment. I've read through Reblitz' method using the string, but would like to maybe buy the Lowell Gauge or the generic dial gauge Schaff sells. Any comments/suggestions? I like the way the dial gauge looks.
