I do some minor metal work and automotive work in my shop and was wondering
if it is possible to heat parts with propane? I mean realistic to try and do
this. Since my shop has a very large propane tank I thought it might make
sense to just try and use the propane to heat up parts that are stuck or
need to be expanded slightly. I was thinking of trying to cut with it. Is
there anything I can do to get more heat out of the propane?

OR do I need to just go get a set of acetylene and oxygen tanks? What am I
looking at for regulators and tanks (filled?)
