Step 6Make a Magnetic Coupler
Now you need to make a Magnetic Coupler to enjoy getting useful energy out of the Tesla Turbine device. We'll use the same technique as the CD Disc Pack.
Start by placing a CD on top of the previously made CD Disc Pack. Line it up with the other CD's. Next, place a small drop of glue lined up to a magnet point on the CD. Take a 1/2 inch x 1/8 inch neodymium disc magnet and place it at the magnet point, on the glue. It will self-position quickly; just be sure not to let it hang over the edge of the CD as the glue sets.
Repeat at the other 5 magnet points, so that you end up with a CD with six magnets glued to it. Flip it over and glue on six 3/8 x 1/32 inch disc magnets, allowing them to attract and align with the previous six magnets. Again, be sure magnets don't overlap the edge of the CD as the glue sets.
Place this 12-magnet CD on the CD spindle to keep things lined up, then put a small drop of superglue on each of the the six visible magnets. Place a CD on top of this and glue it to the magnets. Glue on six more 3/8x 1/32 magnets, and then another CD. Glue on 6 more magnets, this time use the 1/2 inch x 1/8 inch magnets.
By now you have a 3-disc pack with magnets on both sides. This is the Magnetic Coupler. I added some stick-on Teflon pads to the Turbine side for smooth running,
Be sure the North-South polarity is the same for each glued magnet. In other words, you should end up with all south poles on one side of this Magnetic Coupler and all north on the other, similar to the CD Disc Pack previous.
The Magnetic Coupler should tend to repel the magnets in the CD Disc Pack, when placed at the top of the CD case.

Halloween isn't exactly about practical. I was focussing more on menacing. There are practical applications, mostly filled by machines more suited for the purpose than CD's and a few magnets. I was able to cut a piece of wood with it however!
