To the PSN community,
Please check out
http://www.myeclectic.info/SeismoPivots/seismopivots.htm
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. 

Regards,
Charles R Patton
