Seating/false beats

[John W. McKone]

Hi all!

Geeze... A guy takes a few days off the list to take care of his new kid
and everyone beats him to the answers!

I was going to talk about the discussion I had with my Physicist Father in
law, and the conclusions we came to about vertical verses horizontal
termination, and sidebearing vs. downbearing coefficients of friction. But
now - darnit - it hardly seems neccesary.

Thanks to all for their input on this issue.  Its been fun to see a
discussion move toward consensus as people on the list put their
considerable talents toward a problem.
This thread - and the one about optimizing repetition remind me why this
list is the best resource around for continuing education.  Keep it up
folks!

This whole issue has made me want to look at the bridge pin/bridge system
and how it responds when a note is played.  Has anybody come up with a
fairly complete model for this.  If not, can we discuss how such a model
might be designed an tested?

Some things I have in mind:

1. What does the b. pin look like at the top vs. the bottom as it vibrates.
and how,
     exactly, does this change with a slightly loose pin
2. How does the above contrast with the bridge material directly adjacent
to the pin.
3. How does the model change with the introduction of foreign material
around the
    pin (i.e. epoxy or CA)

Just meant to be a start.  You fill in the rest.
