loose hammer heads

[Lynn Rosenberg]

    Put the action in an action cradle, turn it upside down and use vinegar
on each hammer shank where it contacts the head. It softens up the glue,
then the glue rehardens and all is fine.. Also, you can put the action in a
cradle, turn it upside down and apply pinblock restorer, to the joints.  It
swells the wood and the looseness goes away.  Lynn
