Home made fish smoker

I found a couple of pieces of metal that seemed to fit together quite well, I've no idea what they are from but I figured I could put them to some use. So I reckoned a fish smoker would be ideal,

I think it'll work quite well, I can use a gas heat source or even charcoal and I'm pretty sure the result will be tasty smoked fish either way, time to get the mackerel rods out again !
