Bill,
It's about a three hour operation (not including the reregulating
time) entailing taking each hammer assembly off and cutting the
knuckle leather close to the shank on the hammer side of the knuckle.
With the core exposed, I sand the bottom half of the core down until
I'm left with 7/32" from shank to end of what's left of the core.
Gluing pieces of action cloth to the core with a hot glue gun, nip
off corners of the new cloth, I glue back the knuckle covering with
the same glue gun, stretching it fairly tightly.
I therefore have done two things: reduced the diameter of the knuckle
and have corrected a too loose knuckle covering.
