48hr Temp Test

I ran a long run, almost 48hr run test this weekend. The purpose of the test was to see if temperature variations in the room caused a deflection on the torsion bar, as well as to see if there were any background vibrations that I needed to be concerned about. Also at the end of the run I did a dry run of a full test. Here are the results:

1-Temperature variations in the room did not appear top cause any twist in the torsion bar. It consistently oscillated between the 143 and 147mm mark on the measuring tape, regardless of the temp.

2-Review pending of the building vibrations.

3-Sadly, it appears air movement in the rest of the house causes a visible sway on the torsion bar. When I came home at the end of the test, I opened several windows outside the room because it was hot. About the same time there appeared to be a sway generated at the same time. As the torsion wire is outside the box, theoretically this could be cause air movement outside the box. Air movement outside the box can't cause twist to a wire, but it could cause a sway. I plan to add a PVC pipe around the wire to mitigate this. I initially hesitated to do this as it could be used to claim there is a motor or something inside the PVC causing the oscillation. But to prevent swaying due to air currents, PVC will be added.

Because of this update, I will be delaying my first official trial run by several weeks.

Thanks everyone for following.
