Hi Moonshot - Coming along fine. Just a thought since you have gone down the "solid" construction line think about aluminium. Will look the same as the granite machine but you can have the parts machined so you get all the features very accurately. Will be exceptionally stiff and you will know the stiffness. Granite ranges from 50-100GPa stiffness and you will not know the stiffness of the slabs you get Al=70GPa. I appreciate granite is damper but a very stiff machine does not need damping (broad statement machines do need damping) keep at it. Peter
