Willie,

Just a thought: the 5 minute J-B Weld is only rated to 300F iirc, whereas the regular J-B Weld is rated to 600F. I don't know if that is important, but it might be.

I'll let you know about the other stove design. First I have to drink some Guiness, then help finish up an Eagle project - no, wait, it's the other way around...
