Router Spindle Mount Improvement

In this Video I am further improving my CNC Router by installing an additional Router Spindle Mount.
Adding a mounting point to the top of the spindle is supposed to reduce chatter as reported by many DIY builders.
There is no static movement of the spindle itself in its existing mount however that can look very different dynamically.
To quantify a before and after change I like to make a measurement. So the iPhone it is but understand it is not the ideal tool for the job as its accelerometer can not measure higher frequency's.
However I was able to detect a difference with the Spindle Mount installed. All the charts you see in the video are from the Vibration App and the axis are time and g-values. It was an interesting project but please take the charts with a grain of salt ... these are not professional vibration tool results and for all I know it is all backwards LOL.
