There were also issues with builders overheating the tubes. Used to be that Reynolds used to have builders pass a certification process before they could buy 753, consisting of a lug and couple of tubes which the builder would braze together and send to Reynolds for evaluation. They required the use of silver rather than brass to reduce the risk of overheating- except for Norman Taylor. Reynolds allowed him to use brass with 753 because of his skill with a torch. I suppose building 8500+ frames teaches you a thing or two. -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
