These look like a great tool to have around. At $500 it's a bit pricey though!

Inductive heating - used in industry. Pretty neat way to do it. Maybe they'll figure out ways to make them that will hold up OK for occasional (DIY) use without breaking the bank. I wonder if there are some articles on the internet on building them from scratch.

EDIT: Here's how to do it: http://www.rmcybernetics.com/projects/D ... heater.htm
That was just one link from a Bing search - there may be other articles as well. They tell you how to DIY, and they offer the main parts for sale.

Here's their video:

Lots of other youtube videos on the subject. Here's one that uses parts cannibalized from a microwave oven and nothing else:


There may be even better articles and you tube videos:

Ideal for the situation in the video that Craig posted - the heat will be greatest on the outside due to the skin effect, so the nut would get hotter than the rod and expand more.

Yeah, I have to laugh when I see people applying a torch to the stud instead of the nut. Years ago, a friend and I got a ball joint off of a car by heating the nut with a torch while dribbling cold water on the stud.

These heaters are used a lot in industrial settings where an open flame is prohibited due to flammables in the area. We need to send a picture to Harbor Freight - they will have it in 6 months for $49.99.

The tool rep that calls on the school had one of these as a demo a few months ago. Works real well IF you have access. Another rep that calls on us has another approach. "Freeze" in a can to chill and shrink parts to release them.
For now if a little PB or FIRE doesn't get the job done :ohwell
