Mark, I don't know what vintage those parts were, but the centers in =
Tokiwa parts were recently redesigned by someone from Yamaha, and you'd =
have to ask Randy Morton or Bob Marinelli who, and exactly when, but my =
own experience has been no problem since. Although I must say I never =
had the degree of problems you are describing. Over the years I have had =
similar problems with Tokiwa,=20
Steinway factory, Abel, Renner, and even on a rare occasion long ago =
Yamaha factory not to mention many minor name manufacturers. The culprit =
almost always is a bad run of bushing cloth although it can combine with =
improperly dried wood so that the hole itself is moving which I have had =
with Abel on occasion. I use all these brands in order to better meet =
the needs of a particular project and to not have my eggs all in one =
basket should a "bad run" appear. However, as of now current production =
of all these manufacturers seems to be good. Does anyone have more =
experiences with new parts to share? as if I had to ask. Chris Solliday

I have installed two of these sets of Miracle-Wips, one in my own =
piano and one for a customer. On my own B, they provided a better =
touch-weight than the Renner wips (even with the springs disengaged), =
and I was able to remove some lead and easily regulate the springs to =
achieve an extremely even touch. Now for the bad news - over time, many =
of the centers have experienced a sudden increase in friction. This =
seems to be particularly the case with the jack springs, where I =
measured the friction at between 20 and 40 grams! Another rebuilder I =
know had the same problem (and was sued over it). My shop partner has =
also had similar problems with at least one set that he installed. =
Repinning seems to be a permanent cure for this malady. The other set =
that I installed has not had any pinning issues so far (about 18 =
months), but my piano just had two more jacks seize in the last couple =
of days (the first in more than a year). I would say that I've repined =
about 25% of them so far.=20
=20
The other problem is with friction in the repetition spring slots. =
After a while, you'll get a little "tick, tick" sound as the spring =
slides in the slot. This seems to come with use, and has been a problem =
on both of the sets that I installed. At Bob Maranelli's suggestion, I =
applied McLube to the slots, but the problem returned in both cases. =
I've since tied protek, but too recently to predict the long term =
success.
=20
I also just repined a complete set of Tokiwa shanks that had =
virtually seized. Touch-weight was well into the 80's! My advice is to =
stay away from these parts, unless they are going into a piano that is =
serviced constantly so you can keep an eye on them.=20

The other cost effective, and easier to install, and MUCH easier to =
regulate option is the Miracle-Wip from Pianotek or Pacific. These are =
made by Tokiwa and have excellent centers, adjustable heel positions =
forward aand back in a slot, etiher angled or straight and once you have =
used an adjustment screw for setting the weight you probably won't =
settle for anything else. Chris Solliday =20

I got this response from the inventor of the magnetic system used by =
Fazioli and others. His new invention
or application of magnets to piano action is called "Magnetic =
Friction Reduction". This is viewable at
the inventor's website as peviously posted. The new information is =
about retrofitting an action
to this system.
=20
While the cost is less than the previous system used in the Fazioli, =
it seems to me it would be less costly if replacing whippens to go with =
the new Turbo-whippens w/assist springs, rather than buy a set of new =
whippens, and this retrofit kit, and have to retrofit each whippen AND =
hammer shank. I think as nice as it sounds, I'll have to pass. Until =
someone manufactures replacement parts w/the magnets already installed, =
at
a price comparable to a set of turbo whippens, I don't think this is =
a cost effective way to go. Maybe one
of you deep pockets guys will give it a try and report back?
=20
Anyhow, here's the hot poop on this hot and magnetic topic:
>>>>>>>>>>>>>>>>>>>>>>>>
=20
The MFR system is indeed available as retrofit kit. The retrofit kit =
contains magnets, magnets already glued on the adjustment screws, two =
magnet positioning tools and glue. An mounting instruction manual is =
also available and will be send by e- mail. The price is Euro 600,00, =
exclusive transportation costs. The estimated time needed to install the =
system is about 1 or 2 working days. The kit can be ordered by the firm =
