Odd pin block

[Rob & Helen Goodale]

I've seen this on many pianos, even new.  I'm not certain about the logic behind it other than perhaps someone thought that it would reduce moisture problems or enhance structural integrity.  I fail to see the connection.  The most significant problem is that if the pins should become loose in the future the hole may not be deep enough to tap the pins further down.  Furthermore if someone attempted this without realizing, they could split the bottom ply apart which would not improve the situation in the least.

  List,
  I'm not the sharpest on new pin block installation but today I saw something that seemed odd.  While tuning an old Baldwin Grand from the thirties I pulled the action and for some reason touched the bottom of the pin block.  It was not drilled all the way through!  I don't think I have ever noticed a shallow drilled grand pin block before.  This got me to thinking about reasons why someone would drill this way?  I came up with 0!  This was a pin block installed by a technician here in the area.  He is not on this list and to be truthful I don't think much of his work.  So maybe its just one of those odd jobs that a less skilled technician would perform?  Or maybe its a common method used on grand pin blocks and my blind a-s just don't know it?  The grand blocks that I have dun, or helped do were drilled all the way through!  So you guys tell me.  What gives?  Thanks!
