Key Bushing Cauls-sizing wrecked mortices

[MICHAEL MORVAN]

Gordon,
    I would like to play the devils advocate. Filling in the butchered 
mortise with epoxy/filler in theory is an excellent idea and what ideally 
needs to be done, that is replacing the wood that has been ripped out. The 
problem is, where do you fill?  To the left side of the mortise, right, 
equally on both sides. This would have to be determined. Mortises, buttons, 
bushings and balance holes have everything to do with spacing and function, 
spacing has everything to do with appearance, and function has everything to 
do with proper regulation and play. One has to be careful with mortise 
sizing cauls. I use them religiously when I can, but they don't work for all 
mortises. Some keyboard manufacturers used a narrow mortise and button with 
a thin cloth while others used a wider mortise and thicker cloth. One has to 
be careful that they don't split the button or mortise on insertion.
