Inconsistent front rail pin size.

[TOM DRISCOLL]

Andrew,
5 thousanths ? It's a piano --not a Swiss watch. There will also be 
variables in caul size, and mortise width, cloth thickness . Relax, rebush 
and replace pins only if their condition warrants.
    Let me guess--Are you or have you ever been an engineer?<G>
    Best wishes,
Tom Driscoll
