In a prior post you state that you have no actual experience working with the new Kawai composite actions.
I do not have experience with the newest
version of the Kawai actions. This does not mean that I don't have experience working on older Kawai composite actions, and it also doesn't mean that I don't have experience playing Kawais with the newest version.
and your signature says that you are a "piano technician in training" - yet you are denigrating an excellent design of a company that has achieved incredible results through their dedication to non-traditional parts and technology.
"Denigrating" is an outrageous exaggeration, and I have no idea how you inferred that from my post. Kawai should be lauded for its pioneering efforts in materials science, especially when everyone else was laughing at them. I don't think the Kawai parts are bad; it's just my impression is that WNG is far superior.
And since you're inferring that, as a "technician in training", I'm not really qualified to have that impression....
For the past two years, I've worked in a university shop, which was a valuable experience. During that time, I've made lots of connections, toured three factories, and done more hammer filing, action regulation, key rebushing, string replacement, center repinning, hammer hanging, and touchweight correction work than a lot of professional technicians, all while studying piano at the graduate level.
You are also implying, perhaps unwittingly, that the M-III action suffers from "high inertia/friction".
I'm saying that most of the non-Shigeru Kawais I've come across (either working on them as a tech or playing them as a pianist) have a heavier touch. Inertia and friction tend to be causes of that, so, yes. In my experience, Shigeru Kawais, which I believe use the same parts, do not have this characteristic.
I have tuned and tweaked many dozens of brand new Kawai instruments, including a fair number of new Shigeru pianos, and I find your statements to be completely inaccurate and somewhat outrageous.
I have stated numerous times, including this thread, that I personally have a preference for light actions. In fact, it's probably safe to say that most pianos are heavier than I prefer.
The action feel on the RX series grands is superb, and in no way does it feel heavy at all. Not once have I found any reason to consider doing any type of touchweight correction on any new Kawai. Every client I have worked with on their Kawai (including some seriously gifted pro players) has been thrilled with the feel of the M-III action.
Touchweight correction is more or less a standard procedure where I was working, time and money permitting, whether it's a 30 year old practice room grand or the concert grands in the hall.
One of the great joys of working as a pro player and pro technician is the chance to experience different instruments day in/day out. This is a gift! If you are more open to celebrating the differences in personality between pianos - and can learn to appreciate the value and distinguishing features of instruments manufactured at different price points - you will be a much more effective technician. And you will also be more likely to provide better service to your future clients.
I agree with you only to a point. If I don't like a piano, I can live without playing it, or working on it (at least for now).
I also feel that if you weren't posting anonymously you probably would not have made these statements. After all, this is a very small industry, and people will remember what you say and do, especially if it involves unfounded negativity.
While this is probably true for other comments I've made around here, particularly about Steinway, I don't think it's true in this instance. Regardless, I am well within my rights to be anonymous, especially since I have no affiliation with any companies and have not yet made a living in the industry. If you have a problem with the forum policy, you can appeal to the moderators. Technicians who have read enough of my posts will probably make the connection if I ever meet them in person, anyway.
