Hi John,

OK on the correction.  Per your web site, that particular "item" had more to
it, than
what we've texted here of course.  I used a mass head reference object and
eyeballed it
when putting the paper size I used down on the mass.  Suspect one might see
the
deflection of the AS-1 mass also if they "look" for it as described, but
without
dampening or the coil hooked up; in free mass response.  Its rather tough to
gauge any verticals sensitivity without further completing the whole
assembly....they
are much more difficult to adjust and maintain overall.

Meredith,

The paper I use is 2 cm by 1 cm, with an estimated weight of 0.0338
gm.  I don't think the
deflection of the boom could be seen with the eye, but I haven't tried.
