They are obviously under-weight and way under-budget, and are using two Kurt vices for ballast.
Perhaps they also

A little more seriously, the parts shown look like they fit inside a 1"x2"x1/8" wall aluminum box tubing with a 45° knockout to attach perpendicular 1"x1" box tubing onto.
BTW, which Haas machine is that pictured? (Is it bad that I knew that solely based upon the steel sliding covers for the back spindle?)
