Special Note about Chokes
I have made one change
in what I offer. I have now done enough testing of the burner and choke
combinations that is has become clear that the "slider" design of choke is
superior, due to the symmetrical and balanced intake air flow it affords,
as compared to the swirling and off-side air flow the "revolving" choke causes.
I am therefore no longer offering the revolving choke as a regularly stocked
option. I can still make one for you, if you want this kind of choke, but
you will need to contact me for a price quote for custom work. It will require
special set-up and milling, so will not be cheap. All burners now come standard
with sliding chokes.
A question that I receive quite often concerns the operation of naturally
aspirated Venturi burners at higher elevations, 6000'-7000', or more. There
is a page that deals with this question on Ron Reil's web site that does a good
job in answering any concerns you may have regarding the heat output of burners
at these higher elevations. Please read the short
e-mail posted on Ron's site. It should put aside any concerns you may have
about using one of my burners. Thanks.
Ron Reil shares his thoughts on forge design using venturi / naturally aspirated vs blown burners.
Sometimes it isn't necessary to build a traditional forge to accomplish
what is needed. Perhaps you have a one time, or occasional, need to take a heat
on some iron, and the time and expense of building a conventional design just
isn't justified. Amos Zubrow of "Iron
Rose Forge & Welding LTD" has provided an excellent example of a quick
to build brick-pile style forge, with the addition
of a Kaowool lined scrap brake drum at the top for his burner mounting. The
advantages of forges of this type are they can be easily modified in shape to
allow oversized or odd shaped iron to be heated, and when the work is finished,
the forge can be taken apart and the bricks stacked out of the way in a corner
when not in use. You do need to consider the heat resistance of the surface
you build your forge on, and in this case it appears to be a dedicated brick-pile
forge base structure. Forges of this type are not as thermally efficient
as a ceramic wool insulated forge, but they will certainly heat well enough
to do normal forging operations. If you coat the interior with ITC-100, it may
even reach welding temperatures, providing you have the bricks placed closely
When you visit Amos' web page, the decorative forged gate you will see
there was made using this quick and easy to build brick-pile forge. Note that
the forge linked above is heated with only one T-Rex burner, which provides
more than enough heat to enable Amos to perform all needed forging operations
easily with this forge.
Here is another "brick-pile" forge that Amos has created, but employing
two T-Rex burners. Brick pile type forges offer unmatched versatility, allowing
the forge to be fit to the work at hand. They can be built using a simple design,
such as shown below, or with complex jack or foot treadle (or both) control
of the roof to allow easy placement and removal of oversized items in

Thermocouple Controlled Forge
The link above will go to the technical documents page on the CBA website where the original paper can be found. Whitney Potter's design for a temperature regulated forge can also be found in his book Digital Temperature Control for the Blacksmith Forge (ISBN: 1449560105). This design could easily be adapted for use with HybridBurners. Two points to consider: (1) Be sure the burner isn't turned into a chimney during the non-firing parts of the cycle -- this can be prevented by mounting the burner with the intake ports lower than the nozzle; and (2) Consider using a pilot light (such as HybridBurners Rocket Torch) that is not run by the controller -- that way the ignition of the main burner is not dependent on the stored heat in the forge -- for that reason it is also a safer scheme. Feel free to contact us with questions.
