Re: copper muffler pipe question
interesting idea with the sleeves.
I welded/brazed/silver soldered my contraption up last weekend. Looks rough. works great! Basically, braze tacked it, ran out of oxygen, used silver solder until the mapp ran out, and then mig welded the rest Even tried to mig weld metal to copper. Didnt work too well, go figure, but the grapes are beautiful. And the engine runs wonderful.
