Hey guys first post here. I'm in the process of building a brake drum forge. I'm using a brake drum off of a semi that I have notched. The hole in the middle is quite large, nine inches or so, and I need to cover it. I am about to cut the top off of a steel drum that I will use for charcoal. Will the top be thick enough to handle the heat of the forge if I were to cut out a circle to lay in the bottom? Or should I go for a heavier metal plate? It doesn't look like it in the pictures but there is still a 3 inch lip for the bowl.
