I just did a Wurlitzer CX piano.  The scale I used is slightly
different than the Wurlitzer scale, with half gauges used: 12, 12-1/2,
13, 13-1/2, etc.  I used Mapes piano strings and Abel hammers from
PianoTek.

The piano came with a soundboard riddled with screws and loose ribs;
glue was slopped all over it.  White glue will not hold a rib in place
that was originally glued with hot hide glue unless all the hide glue
is removed.  The new soundboard was crowned 5/16 to the center of the
board and glued in with hot hide glue.

The original Wurlitzer scale design is not the best as at the treble
tenor break the strings in the tenor are too close to the plate strut,
with the top tenor hammer almost missing the top tenor string.  I have
five Wurlitzer coin pianos that I compared and all have this design.

Currently it is sounding great and I mean _great!_  Strong bass but
the tenor bass break is not as smooth as nine foot grand, but then not
many uprights have a seamless break.

I would credit the new soundboard and hammers for the tone.  I really
like the Abel hammers in this piano.  I want to try a set of Ronson
hammers on my next major rebuild as they are also really nice.  If
you are looking for a hard hammer then choose another brand of hammer
such as the ones from Japan.

Bottom line is "How do you want your piano to sound?"  There are
several choices for hammers, strings, and felts today -- more than
I had in the 'seventies.  I know not to buy hammers pre-bored from
one supply house as they are always off.
