I like to experiment w different woods and different mixes of woods. In order to do so with a minimum of expense and trouble, I have found a use for an old Brinkman vertical smoker. I put an empty pan on the fire pan brackets. A farm plow disk on the water pan brackets. A disk is of much heavier metal than a pan and has a hole in the center for air flow. A brake drum would also work. A grill grate on the top. I build a fire on the disk/brake drum and "cook" some cheap frankfurters after it has burned down to coals. If the wood is not one to be further explored I have learned so cheaply, easily, and made my dogs happy. If it passes this test I try it with some more desirable meats and in a more desirable smoker.
