MH BB Pinblock

[Farrell]

I disagree with Ron's recommendation to not glue the pinblock to the 
stretcher. This is a very important step to stabilize the entire case 
structure. You need to glue the stretcher to the pinblock so that the 
stretcher does not fall off. And being that the stretcher is a very heavy 
duty 1 x 3 piece of  poplar (or did some manufacturer actually put a little 
piece of hard maple in there?) on most pianos, it is integral to keeping the 
sides of the piano case in place. It's your basic knee-bone is connected to 
the leg-bone relationship - just like the circle of sound - if the pinblock 
is not secured to the stetcher, the stretcher call fall off and then the 
case sides will fall off - or at least rattle a lot - or at least the sound 
will leak out. Maybe the sound that travels through the pinblock "reflects" 
off the stetcher and back into the pinblock and back into the strings.....

And maybe it's WAY too early in the morning. I'm going back to bed......
