Clark, You can figure this out yourself. Measure in millimeters the total width of the keyboard from note 1 to 88. Then divide by 52. Subtract 1.5mm for the negative spaces between the keys. 1.5mm is the space found between the heads on new keyboards. I build out the sides with sugar pine veneer I make myself on the table saw. I cut them at various thickness' from .5mm to 1.5mm. I select the heads that need shimming and plane the sides smooth with a block plane. This will make for a better glue joint. I select veneer for one or both sides to get the desired width, usually about 22.5mm. I find that the German single piece plastic key tops from Pianotek (KTF-4W) are just the right width for Steinway grands. These are the same tops Bob uses for new keyboards and are now available cut into individual pieces.
