Look where the base plate mounts to the base and the machine bolts to the base. What actually ties these points together? 1100 pounds of mass with any kind of arm length creates a sizable force. Tying the base of the machine itself to the upper plane as rigidly as possible is the goal. I was thinking to try additional wall supports to the plane of that base plate and see if that significantly dampens the reaction. Could use the lower framework to base plate bolt mounting points.
Agree. I have a large enough piece of 1 1/2" thick granite left from a kitchen remodel. I think if I did the upper support, I would also build a substantial base with the granite on it.
