Your welcome. Let's see. I hadn't considered oval head vs flat head. I guess I pictured oval heads because the flat heads would have to be countersunk and there is not too much thickness to the walls. In any case I would welcome any response on that issue. And yes, I would love a picture of it. my email is

As to the tapered spreaders, I have found JSI in FL to be a great resource. Perhaps they can help you too. (Dave Johnson [djohnson@newjsi.com])
