I've got a wood, laminated leveling stick with a slight crown=
 built into it.   I've used it for years...I can understand=
 eyeballing a few keys but not an entire set...maybe my eyes=
 aren't as good as yours...;-]

hello.
 
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.

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