my usual gig is the genny & a hot box for pvc, alas my genny crapped out today, with the excavator waiting @ $$$$ per hr

long story short, the quickest fix was to use one of those heat wands the roofers use to clear ice dams.

fed by my barbQ gas bottle this bent up pvc quite efficently. of course i had to roast a few to get the right distance/flame/timing of it all

anyhow...
i don't suppose i'm the first here to stumble upon the divine revelation of fire.
