[TheForge] burners

[Dan Brewer]

If you can use hand tools I would build your burner.  They are very simple
and can be built in less than a day.  Except for the blower all of the
parts are available at your local hardware store.  Since you have 12 psi
available I would look at building a Porter style burner.
