[CAUT] durability (was funding)

[David Love]

I have found with the Wurzens that they do not respond to traditional
shoulder needling.  The tension seems to be mostly in the outer layers and a
slightly different method of needling is required.  That method is to free
up the outer layers of felt by needling at an angle of about 45 degrees to
the felt surface starting at about 9:30 and 2:30 with the needles pointing
downward toward the staple.  Move upward toward the crown in a radial
pattern  with maybe 4-5 stitches (3 needle tool with needles extending about
10 mm) on each side for the lower part of the piano progressing down to 1 or
2 stitches in the treble (if needed).  You can do this to within a few mm's
of the crown.  To give some orientation for the angle, when needling near
the crown, the needles will be pointing in the direction of the shoulder.
At the 9:30 position,  the needles will be pointing toward the shank/hammer
molding intersection.  While the needles will be completely inserted to
their full length, the depth of penetration from the surface at the tips of
the needles should be maybe 5-6 mm in the bass progressing to 2-3 mm in the
treble.  Sugar coat over the top as needed.

I would be interested if you have noticed any voicing difficulties with the
Ronsen Wurzen?   It seems to me I get little change with shoulder work and
have to very near the crown...comments?

For the past 2 years I've been hanging only Ronsen Wurzen felt hammers and
I've been surprised and pleased at the longevity.  At the end of a year they
didn't even appear grooved.  Pulling the action and looking closer you could
see string marks but not what you'd call grooves.  That felt is just so
dense that it holds up.  The next 3 or 4 years will tell the story but so
far so very-good.

 I think our Piano

faculty are close to what your Chair does - hammers last about 4 years.  Our

performance major practice rooms make it 2-3 years.  We've tried a number of

different hammers, but the results are not much difference.  We are in the

middle of hanging a set of the new Abel Hammers (Bio felt?).  We'll see how

they do.

 

 

I want to know when you guys have time to change hammers every 2, 3, 4
years....

 

Our concert instruments are serviced twice a week and touched up before each

performance.  I suspect our program may a little busier than yours, however,

which necessitates the extra service.  Last year we had over 600 events.

 

 

...and get all these tunings done in 40 hours a week.

 

Back to work...

 

duh...?

We're having a rebuilding meeting with the dean and piano faculty in the
morning.  We've had virtually no budget funding beyond my salary, and I'm
taking every bit of this thread to the meeting with me.
