It should work and wouldn't be to hard to build. However, it does have the potential of being quite dangerous and is considered a transmitter so there might be some licsencing issues. You don't want to do something like cook yourself or blank the radar at your local airport. I would think that slowly raising the tempeture in a conventional oven to about 300 degrees F would kill about anything. That wouldn't flame the wood but it might be hard on the finish.
