Oh and what software did you used to produce the pictures?

Rick, I am unsure about cutting forces but I was hoping to prevent the gantry flexing back and forth while cutting. I may also add a plate to the back of the gantry between the X axis to further restrict right or left deflection.
I just used Google SketchUp for the drawings as its quick.
