About 9 months after rebuilding and installing a DuoArt stack in
our Stroud Grand,  I decided recently to make some adjustments to
the leather nuts that determine the length of the brass push rods
between the striker pneumatics and the keys, but they are so tight that
even with pliers, I cannot turn the nuts on the threaded rods.  Does
anyone had any suggestions on how to loosen the nuts short of dropping
the stack and taking it back to the bench?

    I did drill and tap the nuts with a 5-32 tap before I put them on.
