Re: making a "weld"
mine was not as bad as what you are describing, but it wasnt really welded at the top, stil secure though... i just dropped some gorilla glue down on it. Worked great, but the JB weld you gto will probably be better especially since yours seems to need a little bit more intinsive care.
I love my little Mini Wheat. The welds arent the prettiest thing in the world, but its portable and smokes really well.
