I'm planning my first DIY propane tank forge this winter, and was going to build a standard venturi burner. This looks much better, and I like the idea of a quiet (or less noisy) forge, too, although adding a fan seems to complicate it a bit. But I have some questions: do ribbon burners require/use more gas than the standard Reil design and similar single-nozzle burners? What do you use for the blower? How long does the cast manifold last under pretty light occasional use?
