Ed, i said carbide but i should have said hardened metal, the device looked
somewhat like a microtome used for specimen samples. Another machine i
recall used 2 steel plates with the ends cut on a 45,wires came across the
plates at an angle,pressure and side movement feed the wire out, a cam
lifted and applied pressure,parts were sheared at the 45 angle. I recall
this from 30 years ago when i was into crystal radios,coherers and the such.
My library of books and papers from that era are long gone. Some of the
coherer stuff i had years ago came from England and Germany. beyond that i
draw a blank. cul brian f.
