So I am about to build this. Like Jay, I have an older Bosch SCMS that I have to accommodate for so my tops will be 30" deep, leaving approx 8" behind the base cabinets for dust collection piping. Obviously the cabinets cannot be attached to the wall. Should I just count on the weight of the cabinets holding them in place? And another question, I will be building and leveling my bases(toe kick area) and then installing the base cabinets. Jay's design has open bottoms as he is putting all drawers in as I plan to do also. By building the bases independently, I assume that I will need to put a substrate on them for the actual cabinetry to sit on, is that a correct assumption?
Total miter saw station will be about 15 ft
