Hi James,

I'm sorry to hear about your problem! I'm happy however to have company in 
the rework area as this is frustrating to all of us.

Best Regards,

Jim K

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?
