> Hi Doug,

                 Most grand back check wires will just 'punch out',  the pilot
hole is usually drilled right thro' the key stick.
Place the back check between the jaws of a vice and use a thin punch to pop
the
wire out from the bottom of the key. I use a 3" nail that has had the tip
ground square. It will not enlarge the hole, and the new checks with wires
will
fit nice and snug, with out having to resort to CA glue or epoxy.
Just another method.
