Subject: Paul Hethmon's new brewing stand
I haven't built a stand yet, but I've been researching this topic myself
for awhile. I'd like to share some thoughts and observations. I have
built a heat shroud already for my existing setup. It's made of thin
stainless steel sheet, with sharp, double-back bends at each end that
interlock when the sheet is wrapped around the burner/pot. A pair of
stainless handles are bolted onto it, at both ends of the sheet, to
facilitate
the bend necessary to install it. Since stainless steel is a poor conductor
of heat, it works like a champ. I support it by attaching three long clamps
high up on the burner legs. With a little welding skill, these could be
permanently mounted support bars.
My conclusion about mounting to a stand is that the burner itself should
be the terminus of the support arms from the stand structure, instead
of the arms supporting the pot, with burner below. The pot, then,
simple sits atop the burner as it would if not mounted to a stand. If
the supports arms supported the burner pot support ring from directly
below, then the support arms themselves would serve as supports
for the heat shroud. This might still work well even if the support
arms were mounted lower on the burner assembly, such as below
and supporting the shroud that usually surrounds the burner jet
itself. As burners can vary quite a bit in design, your mileage may
vary.
Of course, my heat shroud does not serve the same protective role
of the sight tube that yours does. Mine simply increases the
efficiency of fuel comsumption. I don't have sight tubes, so this is
a problem I have no experience with, sorry to say.
Have a great day!
Dave

Subject: Things about brew stands
Hello Paul:
I am also in the process of designing a brew a stand.
Here are a few things I am considering in my decision:
The distance from the top of the flame to the bottom of the kettle should be
such that it does not send blue flame out to the sides of the pot. This seems
like a waste of heat to me. Adjust the burner position to get the correct
height. This is dependant on the burner, fuel pressure, intensity.
Metal loses and lot of it's strength as it heats up and it needs to move as
it is heating and cooling. Make sure the design allows for the movement of
the support or welds could break. I like either the 6 point style as per gas
top cooker or the modified X, both these designs allow the hot metal to move.
I hope this helps
