[Shop-talk] Tool for getting frozen nuts loose

[Pat Horne]

John,

#1 is an induction or eddy current heater

#2 is an electro machining (I think)

Both work really well. 

Peace,
Pat

Gang,

Was just talking to a friend on the phone about all kind of things and
working on rusted items.  I was telling him about 2 tools I've seen, but I
can't remember what they are called.  So I thought someone here would
maybe know what I'm talking about.

1. Is a tool that I've seen you put over a nuts, like a manifold nut, and it
uses some sort of magnetic / rf energy to break the item loose.

2. Is neat tool that will let you actually burn a broken bolt out of say an engine block.

Anyone know what either or both of these are called?  I want to find a
video of them to send to my friend.
