Step 2: Materials and tools

Picture of Materials and tools
All I actually bought for this project were the magnets - small, countersunk neodymium magnets from ebay.

The rest was made of material I already had stocked in my shed - scrap timber, bamboo skewers and a pair of dead ball-point pens.

Similarly, no specialist tools were required - a junior hacksaw with blades for wood and metal, a hot-glue gun, drill and my multi-tool.

Health and Safety

You'll be using hot things, sharp things and very whizzy things. Be careful.
Take particular care with neodymium magnets - they can nip painfully, and will shatter if allowed to fly together.
