Hi Gary,

8020 is 6061-T6 aluminum in an extruded erector-set like form that seems 
to be a standard.  This type of extruded aluminum seems optimal for 
stiff seismometer like structures.  It is easy to configure and quite 
inexpensive as well.

I am curious if others have used 8020 in seismometer designs.

Hi Gary,



8020 is 6061-T6 aluminum in an extruded erector-set like form that
seems to be a standard.  This type of extruded aluminum seems optimal
for stiff seismometer like structures.  It is easy to configure and
quite inexpensive as well.

I am curious if others have used 8020 in seismometer designs.

Subject: 8020 aluminum and approaches to constructing a homemade seismometer

I have come across a source for cut-to-order 8020 aluminum and brackets.

http://www.automation4less.com/store/products.asp?cat=1097

Has anyone tried this approach for homemade seismometers?  There seems 
to be good potential.

Are there examples of 8020 seismometers?

Are there other good sources for 8020?

Robert
