I have read the post a bit too fast. For the hammers You'll get the least
work on them with a re felting job from Abel, and it is excellent how they
do that.

As almost nobody ibn the USA seem to use that process (Phil Bondi being the
first to my knowledge , hello Phil !), you will have little data on that
from the US techs. But it is often done in Europ, for many reasons as
weight, ease of work, time.

Usually,one ask for :
new rollers on the shanks
new centerpins.
This is done as well for the school of Music in Paris on most Yamahas in
Studios.

Hope that helps.
For the strings, we use HellerBass http://www.hellerbass.de/index.html as
most good rebuilders (never heard a complaint).
In  regard of you last question about then speed of life in regard of a
toilt paper, I don't know for sure but we tend to consider that it is the
opposite that prevails.
Let's see , the end of the roll is thinner in diameter, then the speed the
rollis slower.
Nowadays it can be seen like that as well
For the toilet paper, we have a very good provider (I will not say the name
of the journal for politic reasons).

Good luck with the piano

  Good day list,

  Firstly, as a younger person, I would like to apologise for opening a
probably old can of worms before i start shooting my questions. Any response
is greatly appreciated..thanks!

  I am working on a 1975 Yamaha C7 which i have recently acquired...dead
strings, good crown, horrid hammers, and because of the lack of experience,
I am calling on another Yamaha technician to do the job for me. I am from
Singapore, where there is a profound lack of rebuilding experience amongst
piano technicians here (no rebuilding shops) He also left it up to me to
choose the parts as standard Yamaha parts/labour are too expensive in this
part of the world. My question here is:

  I am aware that a good voicer/intoneur/technician will be ultimately
responsible as to how the final result of the piano will sound but
unfortunately we don't have the means to "import" an experienced technician
from overseas or the expertise locally, therefore i need to know, what
manufacturer of hammers AND strings here that the good, experienced folks of
America have worked with that actually sound good with the least
fussing/work done to it (ie. easier to work with :)...as I hope to get a
particular brand for the technician that would enable him to pop the hammers
on and adjust the regulation, and maybe do extremely minor adjustments to
the voicing.

  I have dug up the archives recently and have heard alot of work being done
to Renner and Isaac hammers such as "removing the staples to file away
excess felt" although i have heard very good things about them. I have also
read good reviews on Abel hammers in yamaha pianos, but i am unsure of what
size yamaha piano it was. Any good reports on these AND other hammers for
the Yamaha C7s?

  As for the strings, i was looking at Isaac, GC and Sanderson, and the
question i need to ask here is which one would be easier to work with and
hence, produce a better end result in the hands of a novice (me, who has
only re strung 2 uprights and a 6 foot yamaha,never anything bigger..still
getting my experience) and a yamaha tech who has never restrung a 7'4"
mammoth in 6 years (two people working at once) I am aware that brand is not
as important as the quality of the job done.

  Anyone who has done an older C7 up care to enlighten me on this? Once
again, my apologies for this rather lengthy and redundant query, and thanks
for any correspondence and answers in advance!

  Best Regards,

  Amery Nikolai
  Singapore
