Well lets see if I can now post a pic or 2 for you all .
First up I have a few that make beer

Then there is the smoker .Its gas or coals fired , it just sits on the BBQ or the gas ring on the brewery or even inside on the gas stove , if the weather is complete crap ..
The bottom

After the bottom I can just add the top and a lid

or add more sections with a rack in each

all the bits

And a few fish wings
The little stainless smoker is a mates that he brought down to show me , but by the time he got here I had mine cut out and cooking , lol
I didn't build the fire place but its served us well now for a good few years

well thats a couple more uses for the 50lt stainless vessels , I've got an other project here somewhere but I'll have too dig it out ...
cheers
