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.
