This will probably make a real blacksmith laugh, but if you want to make some metal glow and beat it into new shapes, you don't need a full scale forge.
This lady likes her new torches that turn on and off with the flick of a switch. Judging by how quickly the metal looses its heat, I think it would be better to use a more traditional torch that could be left burning all the time. This would allow you to quickly reheat the work without having to put your tools down, change hands or wave a burning torch around, and generally work a lot safer.
Whatever you choose, be careful!
