I was thinkin of using some JB Weld. Kinda ghetto, but it may work What say you??

I have a chip in my head fin, and a local welder said he can't repair it. ( I don't have the broken piece) Do you think Lumiweld could be used for this, build it up slowly? My concern is that I add to much heat to the head and I'm not sure how sensitive the head is to over heating. Thanks for any experience you can add to this.I've been using Lumiweld for years and that has worked on EVERYTHING (alloy) I have tried it on so far!
I was under the impression that HTS-2000 was an improved type? (I have bought a kit but not needed to use it yet) but unless you try it you will never know?
Obviously the results will depend to a certain extent on the ability of the user.

Thanks for the inputI've never tried a repair on such a large casting as a cylinder head.
It would certainly need a lot of heat which might not be good for the head unless the heat could be mostly contained in the area of the broken fin as the head would rapidly conduct the heat away.
The problem with building it up is the first layer of Lumiweld/HTS/whatever would melt as the second was applied so needs to be done in one go. I think you would probably have to 'cast' the missing section of fin using stainless steel sheet metal to form a 'mould' as demonstrated below...
