Good point. Nothing against lamination in and of itself.
<br><br>
My biggest problem was poor milling of the mortice holes. Not good
when the Center Rail Pin is binding in the hole and you go in to with the
hand-tool to drill it out and it turns into a spider's nest of
fibers... Had to break out the soldering iron. There was some
key twisting but the climate was awful.<br><br>

<blockquote type=cite class=cite cite="">At first glance, what might
appear to be a 3-ply key panel, is actually a 7-ply panel. There
may be 3-ply panels out there, but the ones with which I am
familiar are 7-ply, consisting of three thick plies, with veneer
laminations between the thicker plies and on the outer faces. The
veneer plies are hardwood, and the thicker plies are softwood, as would
typically be used for a solid wood key panel. The internal veneer
plies are cross-grain, and the surface plies are in line with the thicker
plies, roughly in the direction of the individual keystick lengths.
These panels make very stable keyboards, even they are in Chinese
pianers. These key panels are often also reinforced with hardwood
boots as needed for capstans and/or balance pin holes.<br>

Regarding poorly seasoned key panels, I spent several hours, last week,
getting warped keys to work on a solid wood keyboard in a limited
edition, brand-new grand piano of one of the most well-known brands out
there. This would not have happened with a laminated panel, but
they are to proud of their traditional design to try something new.<br>

<dd>Any opinions about laminated keysticks? Same benefits against
warpage; are they too stiff for player comfort?<br>
