It is not as hard as it appears.

If there are not two holes for the wire to go through, make an extra 

one. Then thread the wire in the original, and into the other one, and 

pull tight.

Then a layer of hide glue, and new felt.

Done"

 

John, 

You forgot the most important item, that makes this job sooooo much easier:
The .090" welding rod w/little handles on them. Point the other end for easy
insertion. Insert as you go. This keeps the coils straight and keeps them
from "crushing" when you pull them tight!<G> Each rod is about 30" long, so
you'll need two. (one from each end.)

If y'all haven't done it this way....next time try it, you'll love it. Just
did a console (1970's) with the high acid felt problem, last week. The
customer has been fighting this for all that time and is now ecstatic that
his little piano plays so well!<G>

Oh, BTW, use your center pin nippers to flush cut the excess wire tails.
THEN....glue on the felt.....With hot hide glue! The glue helps to hold the
springs in the rail...so, slop it on.<G>
