First Look: Grimsmo Fidget Spinner
Popular knife maker, and maker of interesting CNC machining Youtube videos, John Grimsmo has released his first version of a fidget spinner. And he's doing it The Grimsmo Way! Which, if you've watched any of his videos, is a bit perfectionist, which is the perfect way when it comes to making fidget spinners.
His first spinner to market is a svelte looking titanium bar spinner with brass weights at the end of each arm. An Si3N4 lube-free ceramic hybrid bearing from Boca Bearings powers this little bar spinner that weighs 32g - 38g depending on which version you get.
Check out the video below for some interesting stuff on what goes on to prototype these spinners.
