I made a couple of fidget spinners out of wood, screws, and a couple of 2 cent coins from Spain. The bearings came out of old Rollerblade wheels. Even after cleaning up the bearings, neither one spins very well, so I think I need to get some ones before making more spinners.
This was a good excuse to buy a Dremel, which I’ve been wanting for a long time. Awesome tool to have. I didn’t buy it until I’d already cut out the basic shapes and done some basic sanding though. The next batch of spinners will be much easier with the Dremel available for the entire process.
