I have included a five page1938 article on how to construct your own
seismograph from Modern Mechanix on my web page at:  The web page SEISMOLOGY IN FRIENDSWOOD, TEXAS,
USA, will take several minutes to download.

I think many PSN members will be interested in the 1938 methods of
constructing an amateur seismograph.  How different it is today!
