Problem #1: you can't braze worth a damn, it's not hard to make it pretty.
Problem #2: you're completely and utterly without common sense.
what the hell are you doing letting your DOG watch you weld? So a mask is good enough for you...but sure it's not gonna hurt the dogs eyes at all? bravo sir, I didn't know dog's eyes were so superior for welding. Can I teach my dog to weld?
Also, welding on a WOODEN cabinet full of FLAMMABLE materials? My god.....does that really need to be pointed out? I figure you'll just blow your nuts off someday, because a man so inept in common sense shouldn't procreate!
So you started off with a heavy stock system...and ended with? Oh another heavy stock system but uglier, that makes sense?
I also notice you still have tools in their original wrapping hung on the wall. Good, now go return them as you obviously have no mechanical abilities.
oh, and flex pipe? really? yeah because that gives great smooth airflow...
