[TheForge] On the table monday.

Mickey, 
Regarding your search for methane, have you tried MAPP gas?  Welding gas
suppliers are starting to carry cylinders of this liquid fuel now.  Slightly
hotter than propane and way cheaper than acytelene.

Chuck,
Frosty covered the "gun burner" subject already; they're also commonly
called
fan burners. Really, there is a lot to be said for gun burners, I wouldn't
think
of using natural gas any other way. OK, I'd also make up a hand torch using
compressed air-methane after going to all the trouble to pipe natural gas
out to
the garage, who wouldn't? Then too, it would make a real spiffy fuel for a
ceramic chip brazing hearth (greed, greed, slobber, slobber). Recommending a
fuel that is famous for 87% SECONDARY flame combustion may seem a little
bizarre
coming from me, but spreading the heat that way isn't likely to melt the
brazing
hearth chips and grill parts either! This is just the kind of thing I meant
in
2004 by "one shoe size does not fit all." Rather, "a place for everything,
and
everything in its place." If you had ever seen a compressed air-natural gas
torch used for heating silver, etc., you'd not soon forget the site; very
nice.

A gun burner has a blower supplying the air. Naturally aspirated means it
draws
it's own. Almost all oil burners are guns though it is possible to inject
oil at
a sufficient pressure to induce compustion air it isn't common at all.

On the oil burner front, the recent trend is to use an air brush as the oil
atomizer/injector. From what I hear from the pottery kiln and casters, it
works
pretty well.
