as a downside the vibrations from the motor are strongly coupled into the machine since I installed these aluminum motor mounts. I have not seen yet if it affects the surface finish, but it will. I just don't know if it will matter. we'll see. if it screws it up, I'll have to put on some more expensive rubber mounts with the knowledge that they fail about every 10 years of less.
