I'm trying to rejuvenate an old pair of rimless glasses, which are an unusual design, and were customised by the optician who supplied them, who was a very accommodating bloke.
The nose piece is fitted to the lenses by a threaded 1.3mm pin and a thick wire which go through a drilled 1.5mm hole and a dremelled slot respectively.
The arms 'wedge' over the thick wires and tiny nuts hold them onto the threaded pin (the arms connect to the nose-side of the lenses instead of the ears-side, which is the unusual feature that I like about them).
The wires must have been bent around the slot after the pins inserted through the holes, so I had to slightly bend them to take the nose piece apart, that's why they look slightly mangled, but I can put that right when re-assembling them.
I seem to remember he called it a grommet which held the pin in the hole, years of nose-grease has rotted these grommets/pins/tubes away, I can see various grommets etc on optician suppliers, but most are for "normal" rimless frames, e.g. these double pins
I think what I need is like a bushing 1.5mm od, 1.3mm id maybe 2-3mmm long, clear plastic ... any suggestions?
Preferably without having to buy hundreds of the things from the USA.
