One evening last spring, I was sweating
together some copper water lines in my
unfinished house. As my acetylene flame
scorched a joist, I realized that I needed to
find a heat shield so that I wouldn’t burn
down the house. It was late enough that a
Home Depot run would have finished me
off for the night, so I cast about for a substitute
for a commercial heat shield.
Lighting onto some scraps of Hardi-
Plank siding, I knew I’d found a winner.
Composed largely of concrete, I was sure
that the Hardi-Plank wouldn’t burn. I jigsawed
a slot into a scrap so that I could
slide it over the pipe near any framing, and
went on sweating.
