For those of you who do large-scale coil construction or other such work an=
d
need to stiffen the clay quickly, someone on eBay is selling four brand new
Sievert roofing torches. These are top-of-the-line torches, including
regulator, hose torch body, and two torch heads with quick disconnects.
This unit normally sells for around $170, but they are listed as "buy it
now" on eBay for $75 with free shipping. I have been using one of these
torches for years. It puts out a maximum of 375,000 BTUs, and heat guns,
hair dryers, and standard self-contained propane torches don't come close t=
o
the power and efficiency. This Sievert torch does not have Piezo instant
ignition, but is easily lit with a spark igniter, and has a pilot light
feature that can be set to whatever burner flame you wish, and then you pul=
l
a lever to get a larger flame, which is set with a separate knob.

I have no idea who the seller is, and no connection to them, but I wanted t=
o
spread the word about these torches. I was tempted to buy another one
myself, but the one I have is in perfect condition, so I really have no nee=
d
for a second one. To see these torches just enter "380259409900" in Google
or in the eBay search box, or go to eBay and search "Sievert Roofing Torch.=

Regarding my post about the Sievert roofing torches offered on eBay, Lee
Love asked:
"Can they be used to raku fire?"

Lee -
I know that a lot of people have used the far cheaper Harbor Freight roofin=
g
torches as raku burners, so I see no reason at all why these would not work=
.
As I mentioned, with the larger torch head attached, these things put out a
maximum of 375K BTUs, and that should be enough to fire a raku kiln of at
least four or five cubic feet. Two of them would fire seven to ten cubic
feet, and $75 for a decent burner with hose and regulator is a good price.
It is important to point out that the burner body is not the heavy cast iro=
n
we are accustom to in venturi burners, so the burner should be placed at
least a few inches out from the port, so as to prevent overheating and earl=
y
failure of the burner tip.
