Step 3Make the CD Turbine Disc Pack
Assemble Disc Pack :
Working with a CD Spindle and your favourite useless CD's, open Spindle Cover and remove CD's from the Spindle. Crazy-glue six 5/16 inch x 1/32 inch neodymium disc magnets in appropriate locations, evenly spaced at edges on one CD, as in the picture.
Use a piece of medium sandpaper to rough up both the surface of the CD where the magnet will sit, and also roughen the mounting surfaces of each of the magnets. Use only a tiny drop of superglue for each magnet.
Flip over CD and carefully glue six more magnets onto CD to correspond with previously glued magnets on the other side. They will tend to pop into place at the correct locations "automagically". Make sure they don't overlap the edge of the disc.
Now put this first CD onto the Spindle of the CD Case. Put a small drop of glue on each magnet, and place another CD on top of the first. Glue on 6 more magnets to that CD. Put small drops of glue on the magnets. Place another CD on top of them. Continue in this manner until you build up a CD disc pack with 8 discs using 60 magnets.
