Finally after some time, the process it's done!!! I needed to test the sanding down every moment.
I've used a metal press and sand paper
The adjustement was perfect, the lever pushed the crown with the propper strenght
Now I have my own 360, the Paneristi boys didn't answered my e-mail .
I don't like 100% replicas so I've used a customized 195 caseback instead.
Cheers!
