How Do I Build an Inexpensive Cold Smoker?

How do I build an inexpensive cold smoker?

You can build a cold smoker using an oil drum for the main smoking chamber. In Oil Drum Handicraft, you can find instructions for how to build a smoker. This homemade smoker isn’t as easy to regulate as an electric smoker that you can buy, but you can build it inexpensively.
