What a relief to see someone mention oxy-propane. I've been using it for
years, especially in the "home" shop. The soot from acetylene is not welcome
in the confines of domestic habitation. I happen to be using a Smith's torch,
very old but still usable. The oxy-propane is a little more difficult to
regulate, but with a little practice you'll learn to get the proper 'roar'
from the flame, and it's CLEAN.
PLEASE, do not use concrete paving stones, blocks, sewer tile, etc. Get some
of the new lite weight fire bricks and keep them dry. A little bit of
moisture in rocks or concrete can produce some devastating shrapnel.
Keep you steam up!
