Pinblock fitting

You're taking up stretch in new strings.  Tuning 
stability is also a function of how many tunings 
have occurred since stringing.  Filling gaps with 
epoxy will help prevent micro shifting but the 
changes you're talking about sound more like 
typical new string stretch.  Figure monthly 
tapering off to bi-monthly tunings in the first 
year.  That can taper off to quarterly tunings 
during the second year and than three in the 
third down to two annually.  Or, the owner can 
tolerate out-of-tune for years if he chooses.

Good luck,
