[pianotech] Worst Bass/Tenor Crossover in Universe

[Encore Pianos]

Are you speaking of an existing bridge or of a bridge to be made up?  

 

Beyond minimal penetration into the surface of the maple the epoxy is applied to, I do not believe that you will achieve a through and through penetration of the maple of an entire bridge body.  It can certainly serve as a vapor barrier and minimize the movement of the wood as it responds to humidity,  To the extent that the bridge moves less in response to humidity, that would aid in the longevity of the bridge.  

 

There are many who use no surface lube because they do not believe that it has any effect on the movement of the strings across the surface of the bridge.  For myself, I use graphite or McLube to give these aging eyes a better visual when I am notching and drilling, and I will vouch for that.

Does anyone here see a problem with using a penetrating epoxy, such as West's, on an entire bridge in order to add some density for better vibratory transmission, and impede cracking? If used, is there any top surface lube that works better than others? (I've painted on McLube molybdenum after scuffing the cap with fine sandpaper, and it seems to work well.)

The board can be driven into chaos at surprisingly moderate attack levels everywhere in the scale. I've been told repeatedly by techs who ought to know better that this is a feature necessary to good piano sound, largely because mine can't.

Adding bearing to these boards would improve nothing. They are just not stiff enough.

It depends on how we want a board to perform, I think. In my experience, there is very little resembling a consensus on what that is. There is also the mass of the agraffes to deal with, which will most certainly affect the performance. So tell me, what's so wrong with the current bridge pinning and notching system, if done well, that is inferior to agraffes?
