Hi all,

Drums you say.....I'am not sure about the description, but
if they are like the old single drum GeoTech variety (?), their value
might be more useful for their content of materials, than for their
original use.  I chopped up one old GeoTech (drummers
cringe!...ha) some time back.  It has three main parts that
offered some seismo potential; it had a solid cast aluminum
box frame (open top/bottom, but still very useful).  Any
added parts like magnet/s etc., would need to be mounted
on the side of the aluminum "box".  The drum itself contained 4
brass counterweights (mass), and the drum shell could make
a nice (additional project), S-G cover.  It also had a
variety of other possible useful parts like other aluminum,
steel cable which could be utilized into a homebrew seismo
with alittle adoption engineering.  Its a good thing, that there
are no "drummers" reading this......ha.
