We start with standard steel bridge pins (which we purchase through Baumgärtel in Germany), then buff the top section which will be visible in the finished bridge, clean with thinners, mount in a polypropylene sheet, deliver to platers. After plating we heat treat at 260 dgrees C for four hours to harden. For those who are curious, we are using mid phosphorus EN plating. In all, its quite a bit of trouble. We have done this to see how it works out in reducing the crushing effect of the wire on the pin. The deformation of standard steel bridge pins is quite severe. By the way, how did your quest for getting to Rochester work out Gordon? Are you going?
