My heat exchanger failed (sea water was entering the coolant side) ... so I could either buy a new one, or make a new one ... the procedure was not so difficult ..

First make all the new parts



Then make a test assembly:

 




Solder the internals with silver solder (~650 á 700 celsius) and replace in the outer conatiner with "soft" solder Pb/Sn




I included new rings to reinforce the tube, as the outer was very thin, but now it is complete and ready for another 30 years service.

Hello Robin,

Thank you for this post.
I'm really impressed by this precision work ! 
Would you send us (to Gerard) some more details on the process and materials used, we could post a good article, like the two others you did.

Your sincerely,

Michel
