Subject: Paper on seismometer pivot systems

To the PSN community,
Please check out
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.
