The main reason I placed the Y rails in the postion shown was because if the rails were side by side on the vertical plane the all the balls at the top of the bearings would be taking the wear.
Also after I started to look at this design more, I also liked the fact that I can adjust the top rail to help square up the spindle to the table in the X direction. I will use the spindle mounting screws to square it up in the Y direction.
