<DIV><FONT face=Arial>Dear David</FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>Good point!! To ensure that the tank is free of propane,
simply duct tape a piece of garden hose, or a pipe that will fit in the valve
opening, to a hair drier. Then turn on the fan for about an hour. No heat is
necessary.</FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>A secondary hazard may exist if there are hydrocarbon
liquids inside the tank. When the heat from a cutting torch or grinder
contacts them, they can also generate explosive gases. Heat the "area to
be cut" without making penetration, while leaving the fan running, and then
complete the cut. This should be safe.</FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>Best wishes,</FONT></DIV>

<DIV>I was just given some discarded propane tanks of various sizes. I
plan to have a friend, who is welder, cut them up and see what we can come
up with for a stove. My requirements for a stove is that it has to be easy
for me to use, cost not too much, and last longer than they do
now. </DIV>

<DIV>...Su Ba</DIV></BLOCKQUOTE>Warning: Propane tanks can explode or
flare if cut without fully emptying them. It is wise to open the valve
for a week or two in hot, bright sunlight, or fill the tank with
non-flammable gasses (CO2, Argon, etc.) to prevent such problems for the
first cut. Remove the valves, if you can.<BR><BR>Dave
