10 x 5 ft plazma table build

my 10 X 5 ft Plasma Table build. V slot bolted to a larger steel frame. 3rd try at bolting a V slot rail to a steel table. My first second attempts at this failed do to the hand tools i had to use. the V slot needed some wiggle to be adjusted to correct speck. I got this idea from 1970's automotive front fender aliment. my answer was 10/32 extruded U nuts on a backing plate 10 foot long 10/32 X 1.5 inch allen head bolts allow me to recess the bolt head so it does not get in the way of the gantry plate. 3/8 inch holes in the square tube steel gave me about a 1/4 inch of adjustment aliment of the V Slot on the steel frame.
