I saw something in an auto repair magazine the other day that really
intrigued me. This was a coil of some sort, (and these come in
different sizes), that you put over a rusted nut. It claims to heat
the nut to cherry red apparently by induction thereby facilitating its
removal. This would replace a torch for instance and would be a lot
safer when working around a plastic gas tank. The machine that these
probes plug into is very expensive but you can buy a set of these
different size probes for under 200.00 Is anyone familiar with this
type of equipment, and do you know if it might be possible to
construct a generic version of the machine that energizes the probes
to heat the nuts? What is actually happening here? Thanks, Lenny


Would it also activate getter (assuming you can get hold of caesium or
whatever it is)
in a valve/tube , should anyone try and make any ? eg
