  Hi Jim,
  You remove the old wire, and clean out the old glue from the slot. Now =
you have a hole to put the replacement wire in. I always had a problem =
getting the wire to lie in this slot. If the wire has broken off flush, =
I have used a Dremel tool and small bit, and it will either push tho old =
piece of wire out, or make a hole next to it.
   Drill a hole at the other end of the slot, the same size as the one =
that is already there. Feed the end of the wire down the original hole, =
along the slot and into the other hole. When you grab the end and pull, =
it lines the wire up snugly in the hole,  you clip off the end and glue =
the felt over the slots as it was. The wire stays in place, not =
depending on glue.

  Be sure to protect the coils and their alignment, using welding rod as =
mentioned below.
  If it is still unclear, I could make a drawing (simple) and scan it.

      When installing the new hammer rail springs, I have found that =
drilling an extra hole for the spring, and installing it like a French =
butt spring, keeps the wire in the slot. Also make sure that you use a =
piece of welding rod, in the coil when bending for tension, saves from =
deforming the coil.
      I used to get the old wire out, put in the new wire, and try to =
bend it into the slot with a pair of pliers I modified, but I could =
never get it to lie fully in the slot.
      I think it was Brian Lawson, or Jon Page that suggested this =
method to me.
