Paul,
Someone will feel this is a heavy action to play. Take your repsoff and replace the whippen heel felt. Use Pianotek's green actioncloth, medium thickness and that will solve that issue. Replacethe jack punchings to reduce noise and the rep lever punchingsalso. Make sure the centers are
in spec. The shanks you are using may push a .415 keydip makingit "feel" heavy. If you are dealing with the accelerated action, therewas pre-leading done close to the balance rail. Take a bass
andmid-range key and re-move the three closest leads to the balancerail. Move leads as close to the front as possible with a fifty-gramweight on the front and see what you get, if the results along withreducing
molding weight as suggested on these trial keys getsyou there then pull the leads and re-weigh as close to the frontas possible, plug holes, I believe Pianotek sells the plugs. Makethe damper lift just a hair late and you may be home free youngman with 30 bucks of material.

Hi Paul Don Wigent here. It is possible to take wate off the hammers by taking wood from the inside of the hammer tales, If there is some wood to remove.
Remember 1 gram at
the
hammer equals 5 at the key. If you should deside to remove some wood from the inside of the hammer tale, use a small drumb sander on some sort of drill pres or some thing. It can be dun by hand no jig needed.. Between the removal of wood and proper regulation you will have less tw

I installed pre-hung S&S hammers on the '70 S&S D, forced to use original
repetitions because of budget considerations. With the regulation
only
"roughed in," the down weight feels too high to me when I play it. Now I
find it's measuring in the range of 55-60 grams throughout. I have
addressed friction in every area except removing and cleaning repetitions.
I can't believe rep spring grooves, etc., would make that much of a
difference; they don't seem that bad.
The new hammers are hung on NY improved shanks with knuckle further out.
I compared hammer/shank/flange #44 from the original and new sets, and there
is, if I remember correctly, about a 2 gram difference. But the originals
are so beat, I don't know if it's a very meaningful comparison.
Would mixing original 1970 reps with NYI H/S/F cause the geometry to be that
different? I was told by David Kirkland that I could "make it work,"
although using older repetitions wasn't first choice. I know the hammer
weight changed in 1984, but understood that using NYI
shanks and flanges
would be all the compensation that was needed for the additional weight.
By the way, the upweight measures roughly 28-30g. Also a little high, no?
And it seems to me there's a lot of lead in the keys, but I'm definitely no
expert. Doesn't this imply a somewhat too-heavy hammer?
I don't mean to be taking any shortcuts here, but there are time constraints
and a balance/compromise that must be struck with all the other instruments
I'm responsible for. This one is starting to drown me. Just wondering if
this touchweight issue is common when putting new hammers on a Steinway D
from this period, and if there is a typical or common remedy or approach to
solving the problem.
This is only my 3rd set of hammers, and my first set completely on my own.
I'm thinking of attending the PTG hammer hanging class with Mike Carraher
and Keith Bowman in October. Any thoughts
on whether I'll learn skills in
addition to hanging (determining bore angle, etc. and boring hammers, I
assume?) that might help me fix this? Will they address how to arrive at
final touch weight? I want to learn! Guess I should contact Mike or Keith.
OK, now I've exposed my near-total ignorance in this area and am
embarrassed. Thanks in advance for any suggestions.
