This procedure is a bit tricky because such a thin glass cools down very quickly, so I had to be careful to get long enough fibres before they would break.. but it worked also quite well.
However, the thinnest fibre you can get is from spiders :-)

Well done Brendan, Bojan, I love seeing home-made projects!
I used fibre optic too on my finder a while back.
Works well when illuminated.
Stars shine through the opaque centre of the glass.
Not ideal, but dead straight.
