I've finally gotten to the end of the assembly of the stack of plates. Here I've added and positioned the end plate so the vent holes are aligned with the other plates. I use wing nuts to snug everything up so nothing moves once I get perfect alignment. Finger tight nuts work great too. Don't use the nylon insert lock nuts yet as you are just getting the plate stack assembled and aligned at this point. I find the resistance you encounter tightening the nylon insert lock nuts cause you to inadvertently jerk the plate stack around causing the plate alignment to shift. Once you get everything snug and perfect, you can then begin to add the pieces holding the tube fittings (3/8" NPT fittings) and bolt things using the nylon lock nuts. For right now, just snug this up and then check for gaskets being properly in place. Don't shake this about too much or drop it as things will definitely shift ruining your plate alignment.
