Update: SAWDIS Seismometer Project

I spend some time yesterday in testing the SAWDIS Seisometer "balancing" performance after installing the boom to the top and bottom pivot points. I gently hook the top pivot point into place, and then rest the boom arm on the bottom pivot point. With the boom arm in place, I then fitted the lead masses. After making some minor changes I achieved a perfect balancing performance from the boom and main frame.

Before I can continue with the adjusting the natural period, I will have to find a few more bits an pieces of aluminum, metal, magnets etc. I am quite happy with the outcome so far and work will continue as an when I find the time.
