Ben gave me a demonstration on Emile's Pullmax and told me
to give it a try. The Pullmax was used as a shrinker in this
case, and very quickly gave the aluminum the rough shape we
needed. The advantage of shrinking is that the material is not
made thinner but actually thicker than it was when we started.
If we were to use stretching techniques only the material would
have been extremely thin when finished.
