The red ball is a 16 pound shotput with an engraver's vise head screwed into it. The density, weight, and low center of gravity allow vise to be stable without locking it.
The aluminum T-track mounted to the sides and back allow accessories light the magnifier/light and hand rests to mount wherever one wants.
The side racks holds majority of favored tools.
I think it will serve me well in a very controlled, compact, versatile and organized manner.
