I worked my way up from Bernzomatic Oxygen tanks (about 10 minutes on
their TINY torch)... As for fuel gas, I'm using Propylene...stored as a liquid, so a small tank will
last forever!

As far as I'm concerned, that tiny Bernzomatic set up got me into
college.
I never thought of propylene. What do you get that in, a b-tank? Have
you been able cut with it?
