[PSUBS-MAILIST] Battery Pods Question

[hank pronk via Personal_Submersibles]

 James,I can't see any real benefit to having the flange ring protrude inside the pod.  If the ring is flush with the inside, the load still transfers directly onto the pod wall.  You can still have a full penetration weld from one side and grind it clean on the inside.  So why not? that would be how I did it, and you really have no choice if you need the height for batteries.Hank

 Hi All
I am making new battery pods for Skadoc.  I am thinking of making the removable ends slightly different to how I did it on the K.  On that, I put the flanges on to make like a standard flanged end.  However, I made them like you would a hatch, ie with the centre of the flange being welded to the centre of the tube.  So there is overlap on both sides of the ID and OD of the tube.  Bit difficult to explain.  Pic here of the K ones when I was making them.
  K350 pod ends.
The problem with these is that the overlap onto the inside diameter of the tube makes the hole smaller and you cant slide the trays out.
With the new one, I have made rolling trays and I want them to slide straight out.  
So, I am thinking I can make the flanges flush with the inside diameter of the tube.
I have not started this part yet, so any advice greatly appreciated.

​Not a very good picture, but new trays with rollers made.  
ThanksJames
