Congratulations to Charles, Chris and Brett for this fine publication!  I
can readily see many months of work behind it.

The variety of pivot approaches and the improvements noted therein, will
likely make this publication the
most interesting, useful and suggestive of important improvements of present
working seismometers than has been
PSN presented at any time in the past.  The "world" of the variety of pivots
shown should greatly enhance
a lot of exciting interesting experimentation with them!  It readily
deserves a "first reader" status, for those either in entry
or any latter stage of home seismometry building comtemplation.

Again, many thanks!!!

Take care, Meredith Lamb

for the results of a series of discussions between Chris Chapman, Brett Nordgren and myself on the  applicability of various pivot systems to the construction of seismometers.  Comments are welcome as I view this as a work in progress.
The work on this paper got me contemplating the construction of a LIGO X-Suspension using 3/4" PVC pipe with Metglas band bearings.  Something a bit different.
