To the hardware folks,

Does anyone have any mechanical specs, dimensions or operation/service 
manuals for the Streckeisen STS-1 vertical?  I recently finished up the 
preliminary analysis work on the fixed-end leaf spring like it uses, and 
would like to try out some calculations with data that's a little better 
than my guesses of its dimensions, etc.

Also what I'd like to find out are things like how they attach their LVDT 
and forcing coils to the boom.  With flexures? Rigid connection?  And what 
are the effective mass, spring dimensions and thickness, etc.  Info on 
their adjustment procedures would also help figure out some of the details.

I'd be happy to pay for copies and postage for whatever anyone has.

The side-plate boom design with a fixed-end spring looks like an 
interesting approach that might not be too hard to build if the spring 
analysis proves to work out OK.

Best regards,
