[pianotech] Bridges and caps [was YC Capo Bars]

[William Truitt]

I don't know the answer to hard and too hard, and I wonder too.  Although
ebony is a very heavy wood, so perhaps it would have some effect of
additional mass in the treble.  I haven't heard the ebony capped Sauter,
only seen pictures of it.

To what effect? I have a whole pile of ebony veneers left over from  
other projects and have often wondered how they would work as a bridge  
cap. Or maybe even making a laminated hard maple cap with an ebony  
lamination as a topper. I guess I've thought that hard, harder and  
even harder is good for a bridge cap, but is there some point where  
the cap can get too hard?
