Hi Micah read you was making a smoker out of a 55 gal drum and you were looking for a 10 gal drum for the smoker box I just wanted to give you a few ideas since making smokers are my life and I make alot of 55 gal drum smokers if you can find you a open head 55 gal drum you can cut the drum in half and cap the half drum with the cap that came off of it and use it for your fire box thats the method I use it's inexpensive and will give you a bigger firebox just an idea check out my myspace to see pics of one of mine www.myspace.com/astongrills
