I’ve taken the ball bearing thing one step further, I welded one to the end of an old punch. I punch my first hole and drop an appropriate bolt in the hole, do the second , then small hammer tapped around the item to mark the edges in and out. Finish with scissors. By the way, I have an old photo album that supplies lovely paper for gaskets. Seal with Hylomar
I am always interested in any information about Rosengart details or current owners.
