[pianotech] BB Mason and Tenor Cross over

[David Love]

I've done this area several different ways and so far this is the smoothest
way to do the transition that I've found.  They're all compromises but
better than the original.

  Very Elegant looking. How would you critique the sound.

You can't do much without making serious changes but redesigning the bass
scale so it's a bit less heavy at the top can also help a bit.  I don't like
added mass at the top of the bass break, it really needs a longer extension
for added stiffness.  I haven't tried it but wonder if a small extension
attached on the underside of the bridge pushing that small little extension
on the topside out a bit might not help the end of the bridge effect.  If
you are taking the plate out you can simply extend it from the topside but
if not then the underside is all that's available.  
 
Attached is my current favorite modification for an added tenor bridge on a
Steinway B (or others for that matter with low tenor problems).  It shortens
the speaking lengths enough to help with the new wound strings scaling,
doesn't change the strike point that much, keeps the new bridge in somewhat
the same proximity to the rim as the old, creates separation from the low
bass.  A bass float would be ok here too but I didn't do it on this one.
You can see the extra extension off the top end of the bass bridge as well.

So, bottom line guys. The French piano maker Stephen Paulello "string with 
softer steel" isn't going to do much?
 
I don't do any scale redesigning and thought this might be an easy fix :-(
