hey hal , my ring was a last minute hack job i thru together for christmas at the last minute (damm near froze my fingers off lol ) . lots of info on this site or on google which is were i got the idea . if your get lucky you can find a drum that's the right width , mine wasn't . had to cut to fit . if you have to cut to fit the top ring has to be a little longer than the sides .i didn't weld anything just screws for now . if you want i can take some pictures or give you info if you want . when the weather gets nicer i'm going to finish it off with welds . i made mine tall so it can double as a smoker if needed . note , wear hearing protection very loud ! , and it would be easyer having someone hold the drum as u cut as they vibrate like crazy . try find food grade , i didn't but i did a 2 hour wood burn in it before i used it . hope this helps
