[PSUBS-MAILIST] Battery Pods Blunder.

["James Frankland" <james@guernseysubmarine.com>]

Hi Everyone.

I made a cock up and just wanted to see what you all think.

I was machining the battery pods with the stainless cladding.  i overdid it on the last pass and machined back down to the mild steel pipe.  oops.

Anyway, i have re welded it all back so im back to square one.  But i still dont like this method.

The cladding method is awkward and im going to have to leave a little bevel at the edge to leave enough stainless on (second attempt).

And i dont think i'll be able to clad and machine the cap to have the o ring groove without machining off most of the stainless cladding, it just seems like to much machining.  But the alternative is to machine and paint, but then i have to allow for paint thickness and im sure the paint will end up getting knocked off.

I'm tempted to machine the whole lot off and then get 4 stainless rings made up the same OD as the pipe (12 inch).  10mm thick and about an inch in length and weld them to the ends of the pipe and caps.  Then i can machine as much as i like and get a really good fit.

Would that work?  im not sure i could weld the small pipe tubes on without distorting them?

or, i could get 2 stainless endcaps?  Is that possible?  Not sure and that sounds very expensive.

Any thoughts, ideas anyone?
