I'm sorry to post twice in a row, but i just thought of an idea. I remember going back through the memories about the record bowls and how people wanted to know how to plug the hole in the center of the rcord. Well isn't that hole about the size of a hole puncher hole? I was thinking, if one has an extra record lying around that they don't want to use for anything in particular, they could maybe after it's been in the oven for a while, punch some holes out and used the little circle disc to put in the hole? Just a thought, one could either put it in the hole while the bowl is being oven-fied (and hope that it melts to the the record bowl), or it could be superglued or cilicon glued to the middle. Just a thought.
