This is representation of a cell design I have been playing with. All materials 316 stainless steel, with nylon shoulder washers and flat washers for isolation. Currently I am using the same design without all the small holes in it as shown in the original disc pdf. The one in the concept design I will cut today, but will not be able to test till tomorrow. This was based as a heavy duty replacement for mason jar style cells but can be adapted to larger configurations also.
