Update: SAWDIS Seismometer Project

The project is still under construction. I am currently working on the upper suspension section. Here is a picture of the "Cole Ball Bearing Pivot" at the upper suspension section. By reducing the friction at the pivot point and at the suspension point, the detection frequency can be appreciably increased.

The photos illustrate the "Cole Ball Bearing Pivot" in detail. I still have to finish off the pivot points on the metal lathe.

The bottom images show the lead weight that will be used to "balance" the pivot point of the pendulum rod.
