My American landlord over here in Cebu, Philippines got tired of listening to me talk about building a smoker so he gave me the old water heater. It looks to be 50 gallons which is too big for me so I need to cut it. I plan on doing pulled pork and ribs once in a while. Anyways what I see the problems to be is cutting it and then fashioning a lid for it. It seems to be 15" old and outside looks galvanized but inside has a little surface rust so I think cast iron. Does this sound right ? Could I cut with an angle grinder ? If I cut the top off to use as the lid 1) kind of heavy 2) a whole 2nd cut needed 3) I guess I flange the lid from the inside and flange the top of the body from the outside ? 4) and put a handle on it. Or I can just say F it and find a $40-50 used electric smoker off Craigslist back in the US when I'm back there next month and ship it for about $30 estimated allocated.
