Hi Chris,
               wow  thats gotta be the best article with good pics I have so far
seen on the net for a seismometer design !!!

   thanks for digging that one up and posting it. Since moving to Australia I
still havent got a seismo system built up  mainly due to the need to build a
Lehman style seismo.   this is going to help lots.   Nice to have that cm scale
on the boom  it will help to scale the whole unit.
Im sure others will also find it helpful.

    Have you looked at the SEP Manual? There are some photos there, but the black painted Al frame is not helpful  This is the UK school seismometer.
