List,

=20

We just finished a restringing/slight redesign of a 1963 Steinway
upright.=20

=20

1.	We ground down the "bump" and lowered the pressure bar slightly.
This made tuning a LOT better. Easier and more stable.=20
2.	We shortened the apron on the bass bridge (cantilever) to give
85mm (backscale) on the lowest bass note. It was 40mm.=20
3.	It now has Pure Sound stainless wire. This made the biggest
difference. Richer, more stable.=20
4.	Added a small tenor bridge. I'm not sure if this made much of a
difference, but the break does seem to be smoother and the bichords seem
to have a slightly stronger fundamental.=20

=20

A side by side listen with the same model showed vast improvements in
the plain wire sections. I think this was mainly due to the stainless
wire. Also, it tunes like a dream now! Removing the bump was easy and
well worth it.=20

=20

Although the piano is improved, in some ways greatly, I still don't like
the bass. It's better than the old design but still a bit "thumpy". Any
feedback??

=20

I attached a "before" picture and a close up of the bridge changes. The
"bump" area looks like the new 1098s so I didn't take a picture of that.

I highly recommend the "bump" removal and the Pure Sound wire. Jury's
still out on the other changes.
