Hello Amy,

    In his second email to me Gary quoted an email from Tony Lent.  I
    have lots of respect for Tony and so based on that alone I would be
    willing to look more closely at the Spirflame but I am still some
    what doubtful as to how large a piece could be successfully worked
    on with this torch. Their website says that it generates 500 liters
    per hour of gas I looked up the burning rates for my torch and with
    a .070" orifice tip which is my normal tip for small  to medium work
    using oxy propane my tip is rated for burning 425 Liters per hour.
    Propane-oxygen burns somewhat hotter than hydrogen-oxygen and they
    have different burning rates so it is hard to do an perfectly equal
    comparison based only on amount of gas flow. But that is still a lot
    more gas than I ever got out of a Hydroflux unit so I would look at
    it as a possible replacement of my torch for everything  but medium
    to large scale silver, but I like a big soft gas-air flame for that
    kind of work because I feel I get less firescale and have more
    control of large solder joints with a cooler, bigger flame but that
    is a personal preference.
