The eyedisc assembly...

This was also made from Perspex, using the holesaw set.
A length of plastic tube (sprayed silver on the inside) has been used to make the spacers between the discs.

The central rod comprises of two lengths of 'threaded tube' (used in the production of table lamps).
This tube is ideal for illuminated eyestalks, as it gives you the perfect way to run a cable through.

The plastic 'buffer' and bulbholder are detachable,
to allow for future access to the bulb, which is going to be inside the eyeball.
