I have a plan to construct a three-dimensional star map.

I'll get a sheet of white acrylic or coreflute or something like that about 400 mm square, three sheets of clear acrylic about the same size, and a plastic strut. I'll draw a grid on the opaque sheet and one of the clear sheets, plot the X and Y co-ordinates of selected stars on them, and drill holes on the plot points with my finest twist bit. I'll label the holes in the opaque sheet with identifiers for the stars. Then I'll assemble the sheets of acrylic and the strut into a box with two open sides, with a strut to support the floating corner, and the two drilled plates opposite each other.

Then, starting at the insidemost corner, I will pass a strand of nylon monofilament (fishing line) through each bottom hole and secure it with a bead and crimp, thread on a crimp and a bead with colour coding e.g. the spectral class of the star, pass the free end through the corresponding hole in the opposite sheet, and secure it with a bead and crimp or a drop of glue. Then I will raise the bead and crimp to a height corresponding to the Z-ordinate of the star and close the crimp with a pair of needle-nosed pliers.

For a pilot project I will have a go at the nearest fifty stars to Earth, colour-coded for spectral type, and then, with method refined, I might go on to mapping Central Sector in my SF RPG setting, using colour and size of bead to code, say, population and tech level.

Has anyone tips or suggestions to offer?

Hmm. I'm going to have to find a cheaper source of acrylic sheet.
