Here are a couple of shots of the workpiece I mentioned in the last post. It is a series of six #10 frogs (crossing noses to the Brits) for N scale (1:160) model railroad switches (ref. https://en.wikipedia.org/wiki/Railroad_switch ). The frogs are still tabbed into the parent sheet of .040" nickel silver. I don’t actually know which alloy it is. I bought it several years ago from a knife-making supplies place. Probably 60/20/20 copper/nickel/zinc because that is the most common formulation.
The Nomad did an excellent machining job. The “railheads” are designed at .020" wide and came out .018/.019"
