I wanted to do something with plastic CD's besides adding them to the land fill - My solution was to use them build 3-D geometric constructions. I describe here how I used 12 CD's to build a Dodecahedron. I also built a 32 CD trucated Icosahedron, 12 of the CD's must be cut smaller an that takes a lathe,.
Step 1: Materials and methods
1. CDROMs are made of Lucite (acrylic)plastic
2. I connect them by gluing 1/2" sections of flexible lucite hinges purchased from Tap Plastics - $1 for a 12" hinge. 25 joints are needed so you need at least 2 hinges.
3. The glue I used is "WELDON #16 clear, thickened cement for acrylic" Also purchsed at Tap.
4. A single dodecahedron "ball" is constructed in 2 halve of 6 CD's each using a layout jig I will describe.
