13ft x 6ft cantilever router

[sail4too2003]

I've got a set of star 13' rails mounted on a fixture from hell 2.25" x 2.25" x .250 wall square tube (about 1200lbs). Also a set of 6' thk's. mounted to a 4" x 6" x .250 tube. If supported well enough, can I run x axis supported only from one end, without to much deflection. Running two bearings per rail on all 4 rails. Star bearings are 2.25" x 4" on 1.5" rail. Half this size on thk's. X axis will be about 100lbs for just the tube and rails. Not counting the spindle. Also running timming belt. What should I run for stepper, or servo. Thanks

One more revise. I want to cut 3/4" plywood.
