Millennium Mechanics

Never tried it, or maybe I have but I didn't know this type of mechanism existed.

But ...it is certainly lighter. The carbon seems to react well to stresses and, weighing less, the inertia of the action decreases. We will see over time. One problem, compared to wood: the chemistry of the pin holes reacts too much to variations in relative humidity, which is totally absorbed by the felt in the absence of wood.

I have had two in my house, a KG (more archaic) and an RX (millennium 3)

Mechanically speaking, I never had problems with the pins... my only criticism is that the pusher tends to create too much friction with the roller over time at the moment it releases.... if you listen closely, you can even hear the little noise caused by this friction! I used to solve it with a bit of talcum powder on the rollers....

Anyway, beautiful experiences... Of course, if 'over time' means 50 years, I don't know; for now, on 20-year-old instruments, no major problems are found: an environment in which Kawai pins end up getting stuck is not good for any piano.

The Rx 3 that I had also had the Ciresa soundboard and it was excellent

If pianoexpert feels that you put talcum powder on the rollers!!

It doesn't smell and leaves no residue

Anyway, what matters is the result

Agreed... but talcum powder is hygroscopic. Teflon powder would be needed. In its absence, it's enough to rub a little graphite on the rollers or on the walnut shells

It's true, in a humid environment it clumps up and becomes a mess... But for me, there is no such risk

Thank you for your points of view on the matter

I would like to point out the action made entirely of Wessell Nickel & Gross composite materials. It can be seen on the websites www.crescendosrl.it or www.wessellnickelandgross.com

The pin bushings are also made of a composite material, which is undeformable and unalterable.

The action remains lighter, more precise, and perfectly consistent across all 88 keys.

The pianist no longer has to adapt to climatic conditions, which have such a significant impact on the action and the sound.

But does it have anything to do with the Millennium?

ah here we go again, with this story about putting teflon on the rollers; from my experience, one acts directly on the pusher, not on the rollers. If anything, it will be the roller itself that will absorb part of the teflon or graphite over time, but if you already apply it smeared directly onto the roller, the roller itself will get so messy that it will become a block of teflon! So.... let's reflect and ....

Well, regarding what Mr. Fra says, from what I am reading in his discussions, I find him to be a very well-prepared and scrupulous person in his answers (targeted and very technical) on many points, even if he could be simpler towards users who are less knowledgeable about the instrument.

Teflon powder is highly recommended by the American School. It can be applied to the rollers with a finger or a small brush. Any excess not retained falls off. This is naturally in addition to graphite on the wooden parts that come into contact with the roller. It does not clump and significantly reduces friction of the parts. Regarding carbon fiber mechanics, we will see the results over time as well as the opinions of pianists. There is no doubt regarding the increased lightness.

Here we go again, it's the usual story... Coincidentally, these appreciations appear like cheese on macaroni right when a decision has been made to ban a member, from a user who joined on July 18th and currently has only 2 posts, one of which is an introduction and this is the second!

A user who introduces themselves in this way:

"I joined this forum to try to deepen or rather grasp secrets when our leisure/study companions start acting up ...... and given the crisis that has spared no sector, sometimes if you have indications like in this forum, you can avoid calling piano technicians with simple DIY methods where possible."

That is, first presenting oneself as an inexperienced user in the field of piano technology looking for advice, information, secrets, and guidance, which now—look at the coincidence—on the contrary, imposes oneself not only as an expert technical repairer, implying considerable experience in the sector, but even as an expert in the physics of materials intervening in defense of a member who was banned just a few hours ago...

Just to be clear, I would like to restate some netiquette rules that you ACCEPTED DURING SUBSCRIPTION, to be taken as a warning:

Banned or suspended users cannot use other users to post messages. The penalty is the immediate ban of the account lent for this purpose.

This is an article from the monthly Official Piano Technicians Guild newspaper dating back to April 2008. It is proposed by Technician Fred Sturm. A brass brush is also used on the rolls and we can clearly see the results. Then Teflon micropowder is applied

Teflon

I am finishing editing a newly made video in which we test the behavior of talcum powder with water and friction... Subsequently, we repeat the experiment with Teflon powder. Let's hope there are no other issues even in the face of evidence. We have to do this... Put it in writing. However, I hope that on future occasions, when there are divergent opinions, people will count to 10 and perhaps experiment instead of speaking out of prejudice without knowing what they are talking about. Thank you...

Here is the video:

Note how, in the case of talcum powder, very little water was needed to knead it and create lumps, whereas in the case of Teflon, I had to repeatedly put my hand under the water because it kept slipping off my hands, which were waterproofed by the powder. In fact, if you look closely even at the end of the video, on the fingers I rubbed (thumb against index and middle), the Teflon powder spread evenly and the fingers are dry.

I invite you to perform the same experiment...

you are just off track ..... I am not a technician nor a repairman, I guarantee it; if you then also want my criminal record to register on this site and you question my good faith, goodbye—actually, you know what I'll say: go ahead and delete me!!! I do not love prejudices; I have been a member of pianoforum for more than 3 years under the nickname varcama, feel free to check what I have written and how I have responded to discussions; I only expressed appreciation for Mr. Francesco, that's all, but questioning my good faith, I will not allow this; therefore, Dear Mr. Dr. / administrator, delete me immediately and I will never visit your site again! unwelcoming and doubtful!!!

First of all, registering for this Forum is free and open to everyone. There are no prejudices against people, so much so that we do not know first or last names. Indicating age, origin, and other data is optional. It is not that anyone's good faith is being questioned, but rather we have the obligation to specify, up to documentary or audiovisual proof, what we assert, which, although debatable, can and must be discussed calmly. Appreciations of User Fra are legitimate, but they do not interest the discussion. I believe the free nature of our activity, in all directions, is welcome to all members, and being "doubtful" does not seem appropriate to us at all because, as in this case, we take care, in order "not to go off track," to go into details and reassure readers that what we say is not just our free opinion, but a conviction founded and supported by years of research and experimentation. I am personally willing to engage in dialogue and even pleasant face-to-face discussions with anyone on topics concerning the technology of our instrument and piano technique, as well as other experts who participate in moderation and more, whom I hope are willing to do so at any time. It has already happened that I contacted some members and was able to debate and resolve some problems with their instruments. On this occasion, I remind you that for all members, except for reimbursement of expenses for long distances, I am available free of charge to inspect their instrument and go into the details of intervention that are difficult to argue in writing.

We are always sorry when we have to remove a member, by our decision or theirs, but if it were necessary, it must be done precisely for the sake of clarity and respect that we show to our numerous members who read us and engage in correct and polite dialogue with us.

Thank you
