Finished the pre/post casting vibration data. Similar reulsts just in more detail. Epixy definetly reduced the stwels vibration and move its natural frequency down significantly.
Nice strong damping. I experienced something similar when I bought my anvil, it would ring just from tapping with finger nails. I built a stand of Oak including an insert into the frog then glued it all down with Sikaflex. Once set the ringing wasn't detectable by my old ears. I'm sure it is less hassle for the neighbours.
