This company does custom tapered pins in brass -
There are others out there I'm sure.
I would find out what their minimum is and get a bulk order together.

A place I worked for in the past had www.mill-max.com do a custon part for
them,
in the 100's - I would talk to them about a part also.

Does anyone have one of the patch cables, and can they measure the
diameter of the pin and it's length?
The width goes from about .093" near the tip to 0.1" near the crimp. The
length of the tapered region is about 0.32". The rounded tip has a radius
of .046" or so, and the crimp area is about .28" long, accommodating the
stranded hook-up wire and insulation. The wire extends beyond the crimp
into the tapered section, but I can't see in there to determine if it is
soldered or what.
Also, is it a straight pin or like a bannana jack with springy sides?
Miniature banana jacks (not the regular ones) actually fit the holes OK,
but are horribly expensive, and also wear on the soft brass holes.
I've bought some of the stackable jumpers, and used them in a pinch, but
it isn't that great of a solution. (It was actually on H901 lab panels,
which have similar brass grommets.)
