I noticed the bow hairs are attached directly to the board. DAT seems like
a mechanically dicey proposition unto itself. Not as much tension as on the
violin strings themselves, but must be some.

There's some tension all right. We've taken steps to insure the bond
between the board and the frog adapter is a permanent one. At the board
end, the strings are attached to a piezo electric sensor. This is what
feeds back how hard the bow is being pressed against the instrument's
strings.

BTW, didn't you post to a.m.c. a little while back asking what else you
could do with your machining center besides machining? If that was you,
ping me off list, got a link for ya. Tried to email, but got a bounce.
