[PSUBS-MAILIST] Battery pods

[Joe Perkel]

Dan,

That's pretty sound rationale for what you did, I think I'll follow what you did for the purposes of my digital but accurate reconstruction. I'm noticing some detail missing here and there in the drawings, and I do need to understand everything well before I can reasonably hope to modify anything.

Thanks Dan!

Joe

Joe, 
  
On my sub, the forward and aft through hulls from 
the pod to the hull are the vent pipes shown on the drawing.  
The third round piece is actually a solid chunk of steel I drilled 
four separate holes through.  Each hole accommodates a brass threaded rod 
that is a conductor.  Each conductor was held in the center of it's hole 
and the space around it was filled solid with epoxy.  I didn't want any pod 
gasses seeping into the hull.  And if I ever blew a pod cap off, each 
conductor is water tight.  The only problem I can imagine is, if I had a 
complete melt down and the rods got hot enough to melt or burn the epoxy, but if 
that happened I'd probably have bigger problems to deal with anyway.   
  
Rethinking...... I think I have 
six conductors.   I may have put in an extra for a 24 volt tap on 
the 36 volt system.  I never used it though and one small conductor for 
water detection in the battery pod. 
  
Dan H,
