Greetings,  
 I really like to tune around the 100 in/lb mark. 
   The type of pinblock will have a lot to do with this.  I don't expect a 
Falcon-wood block to change much after the first day or two.  If it starts at 
130 in/lbs,  it may lose five or so, but not much change after that.  A high 
grade, five ply maple block will often begin around 140 in/lbs but will, in 
the first several months, drop anywhere from 10 to 20 in/lbs.  
     Repinning an old block?  usually, an old block seems to need only 10 
in/lbs higher to settle there, however,  I repinned a model D for the school 
in 1980, using 4/0 pins following a previously installed set of 3/0.  No 
reaming was done,  I just hammered them in.  I got around 150 in/lbs on a lot 
of them, and to this day, the readings are the same. (Dale Whitehead also 
gets to wrestle this block).  It never settled down!  So, old block repinning 
is a very variable thing.
