Rebuilding for Performance or Show? changes - Isaac OLEG's list

John,
Thanks, I had a look at your site , I liked what I've seen. I have
seen some vertical hammers made by Ronsen in Paris (not in a piano)
and I was surprised by the nice resiliency this have. The shape is
surprisingly near of the old French pianos I know.
If the Dodge machine is used we can expect the tension to be fairly
nice in the process I guess.

I Emailed Ronsen to ask if he could make some replications , for
instance I have a set with a few particular sizes as 14 mm on only the
few heads near the break.
I guess it is easy to do, but I hope also that the price will be
"normal".

Thanks anyway, for these info, your articles (nice rule B.T.W !) and
your recent participation to the forum.

Talking about felts and Hammers, Renner can provide not so hard
hammers lately (since 5 years approximatively) while they begin to use
only Vurzen Filz for their hammers.
This felt is much more mellow that what we where used to, and react
very nicely to needling.
The inside is yet a bit dense, but the tone is perfect for all German
pianos (Viennese or Hamburg) since 1930 I'd say.
We have to ask for medium or light pressing, of course their felting
machines don't give much tension originally that is the main problem I
guess.

With the correct needling we can harden them or soften them, but still
for French piano they are too "massive" and modern tone giving I'd
say.

With best regards

Isaac OLEG
