<<There was no shaping of the end of the wire on
Victor Tungstones. I just confirmed that by looking at a couple of NOS
Tungstones that I have. The wire was sheared to essentially a flat end
shape.>>
That documentation on the net that shows Victor drawings of how the needles were
made shows some kind of burnishing thing rubbing on the end of the tip,
at an angle, after it has been mounted in the shank. Perhaps this was just done
to remove any sharp burrs that were left after the cut, and not to grind in
a perfect end on the wire. Makes sense since every record groove is a little
different, and the end is going to get ground down immediately anyway.
But as noted, any fresh tungsten needle should be played on a junk record
first.
