[TheForge] Chip forge - two approaches

[Rich Maynard]

It seems to me that there are two approaches to building a chip forge. Mikey
is suggesting (as I understand it) a 'firebox' or combustion chamber into
which one of his superb burners is inserted, and above which sits a grate
supporting a pile of ceramic chips (which would be of whatever shape you
believe to be the best - personally my 'broken gravel' alumina seems to work
just fine!)

Option two is like the Flamefast chip forge that I use - which is blown, and
uses natural gas (although propane versions are avaliable, presumably
re-jetted). The combustion in this happens in the ceramic chip media itself
- there are no 'flames' as such when the forge is at temperature. This is
quite interesting, as there would be no need to have any hot stuff anywhere
near the relatively vulnerable metal parts of the burner.

Of course, the difference here is naturally aspirated versus blown burner,
and if Mikey doesn't think that the 'Flamefast approach' would work with a
venturi type burner he's probably right.

Would he care to comment?
