Hi Peter,

The parts for the mount for sure looks good when cut by CNC. I still cut my mounting plates with a scroll saw and drill with a drill press. I am still experimenting to to improve the mount. The best result to now have been to change to bigger and softer front mounts and extending the back support by 20 mm. The front dampers are now D15x8H 40Sh. This is probably not the final result but the vibrations at midrange have reduced and the noice level is down in the air.
