<div>David,</div>
<div> </div>
<div>I've worked on quite a few of these and have not noticed the problems you've stated. Perhaps I haven't hit the keys hard enough to have what you're describing occur. I will check it out this week.</div>
<div> </div>
<div>One thing I do notice on many Kawai uprights is that the checking distance is greater than the factory specs suggest they should be. This HAS caused problems for me on occasion, especially in conjunction with minimal aftertouch.</div>
<div> </div>
<div>The stainless steel pieces in the raised capstan portion of the key are weights. My only question about them is why they are oriented vertically rather than horizontally. It seems like they'll eventually shake themselves loose. </div>

<div><FONT face=Arial size=2>Dear All,</FONT></div>
<div><FONT face=Arial size=2>We are a Kawai agent in our area here in state of Victoria Australia, and of late, we have been receiving the new Kawai 'K' series of upright pianos, with the new millennium actions. I am not sure if these are being sent to the U.S. or not, however I have noticed that model K-3 and K-6 actions perform well when played normally, however when a key is hit hard, whilst tuning, there is a decided change in the hammer reaction. This seems to create a hammer bounce similar to lost motion syndrome, and is most annoying. The only way I can see to fix the problem is to bend the check wire so that the top of the check is bent inwardly towards the spur. This has had to be done on every one we have had, and we don't seem to be getting through to them about it.</FONT></div>
<div><FONT face=Arial size=2>It is not a regulation problem perse, as everything else is spot on.</FONT></div>
<div><FONT face=Arial size=2>Do you have these model actions over there, and if so do you have similar problems?</FONT></div>
<div><FONT face=Arial size=2>The other strange thing about these is the natural keys have a metal stud at the rear of the keys, and the sharps do not. Is this a weight, and if so, why not the sharps?</FONT></div>
<div><FONT face=Arial size=2>Looking forward to your opinions.</FONT></div>
<div><FONT face=Arial size=2>Regards to all</FONT></div>
