Hey guys I could use some help. I traded a keggle for rubber coated keg that I planned to use as my mash tun. When I went to drill the pilot hole I realized I was a little low so I moved my bit just a bit higher thinking that it would round out into the initial pilot hole. Now I have a hole that has a extra little taken out of the bottom, can you help. I would post a picture but I am not sure how. If I figure it out I will post a picture.
