[pianotech] Worst Bass/Tenor Crossover in Universe

Ron:

Is it just possible that you could write a reply without being snarky?  Are
you suffering from PDD (Personality Deficit Disorder)?  It is fine to share
your knowledge about the appropriate math behind Thumpe's question, but why
does the put-down have to come along for the ride?  If you believe that your
intellect and deeper knowledge excludes you from the expectations of basic
courtesy that is implicitly asked of the rest of us, please be informed that
it does not.  No one is excused from acting like a human being, no matter
how exalted their self-image.   

Will

Astonishing as it seems, some of us don't rely on belief. It's a matter of
doing the math on the bearing load and friction differences between a 1° or
less downbearing on the bridge top and the two 10° or so bearing and
friction loads at the bridge pins. Making an attempt to actually quantify
these forces indicates to me that bridge cap friction is comparatively
inconsequential. The visual aspect is certainly real for notching, but it
needn't be a lubricant.
