<DIV align=left><FONT face=Arial size=2><BR>hello.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Up till now, I found nothing as=
accurate than eye balling, for key leveling. I set mid and=
extreme keys right with a mechanician ruler, and then eye-ball=
for the other keys. I'm just happy with this=
method.</FONT></DIV>

<DIV><FONT face=Arial size=2>Hi everybody,</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I wonder what kind of device you use=
for levelling keys.</FONT></DIV>
<DIV><FONT face=Arial size=2>I use the aluminium yamaha straight=
edge which is very handy and practical.</FONT></DIV>
<DIV><FONT face=Arial size=2>But I've noticed that it is not as=
straight as it was when new.</FONT></DIV>
<DIV><FONT face=Arial size=2>It has warped a little since I=
bought it.</FONT></DIV>
<DIV><FONT face=Arial size=2>So I'm considering in buying a new=
one.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Or is there a way to accurately make=
one that will harldy warp or loose its=
"straightness"?</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>A guy I know who went to the Yamaha=
Academy in Japan told me that they were selling another type of=
straight edge there.</FONT></DIV>
<DIV><FONT face=Arial size=2>It consists of a wooden core, and=
two plexiglas bars glued to the wooden core (making sort of a=
"wood & plexi" sandwich).</FONT></DIV>
<DIV><FONT face=Arial size=2>And then it is calibrated with a=
machine so it is straight.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Maybe there is a way to build the=
same edge with good accuracy.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Thanks,</FONT></DIV>
