Nice work. I am sure it serves the purpose and is light!

Some questions though.

1. what is the noise level? similar to YS160 with a pipe?
2. any vibration observed on the test-stand?
3. how many layers of rubbers used? By looking at a hyde mount, I notice there is a trace of dried glue covering the join lines between the rubber and the disk. Do not know if that is CA or not.

Again, I have to say it is a great achievement.
