After doing a bit of research during work hours

that looks like a good idea.
Just need to find somewhere that I can get a barrel from. Are there any threads of build logs I've searched the forum but can't find any that can help me.
Edit: Found these on eBay, Around £27 delivered to my door. Would the Lid be decent enough for a UDS? and I take it this would have to be burnt out etc. ?
