I used a CD fan blade on one of my rubber band powered cars so I thought I might make a video on how to make the fan blade.
CD fan blades are NOT SUITABLE for high speed applications - See my notes below.

Hobby Knife
Tea Light candle
Thick wire or an old screwdriver that you can heat to make holes through disc

* Some CDs are more prone to stress fractures than others.
* Using a hot wire to make holes is less likely to cause stress fractures than drilling holes.
* If any cracks are visible it is safer to throw that disk away.
* CD fan blades are NOT SUITABLE for high speed applications

The car that I used this on is in the following playlist

Generally my projects are for my grandchildren to enjoy. OK, I enjoy them too. If anybody else likes them, that is a bonus. I like to keep my work as simple and basic as possible so that it can be copied easily and improved by anybody who wants to try themselves. I recycle or repurpose items rather than buy new and when I do buy I like to keep it cheap.
