April 2011 - Elsinore Mk5 - some details below are obsolete.
Please see Diffraction Wedge photos below. These were
made from 2mm thick heavy duty vinyl tile. The type used was designed for
floors such as factories or commercial kitchens. Cut with a straight edge
knife (I used a guillotine), edges filed at appropriate angles for a snug
fit, superglued together, then covered with a thin black felt to cover. Make
sure that the centre square hole, that the felt overlaps the inside edges by
2-3mm, so that the holes looks slightly smaller after the felt has been
glued on. Use craft glue from the same craft shop that also sells the felt.
The felt comes in many colours, so if you want something more garish
looking? Up to you.
Later, will post actual dimensions of cut vinyl here, to
assist making your own.
It may be a good idea to use some Blue Tack to hold the
