I am new to pouring ang just got the screwlock tip up mold from do-it. I bought several sizes in hooks but the 1/8 oz. mold calls for a number 1 size hook. i was wanting to use like a 3/0 size. What is the best way to get the hook to fit, or can this not be done? I did a search for modifing a mold but could not find anything. Thanks, John
