A couple of years ago I remember telling Wayne that a heat treated steel pin would be more than adequate for the string length termination. I notice that the latest versions seem to be fitted with such a pin. His latest bridge agraffe has three bearing points, with the overhead pin being in the middle.This is a much improved design over the earlier version, which I suspect eventually might cause the odd bridge to be pulled forward off the panel. Mind you, with around fifteen degrees of string offset down and up, with his latest version, there remains considerable forward pull on the bridges. Of the later 'Aussie S & S' pianos I've inspected to date, his bass bridges still look to be 'doing it pretty hard'.
