My aluminum tri-spinner ( https://amzn.to/2pteqdO ) just wouldn’t spin for more than a few seconds. There was clearly a rub that was stopping the bearing from doing its job. This is my 5-minute fix.
This is a popular problem with spinners: you drop it and the bearing goes out of alignment. The bearing is probably fine, and the hand spinner is probably fine, but the bearing placement is off. If you have a spinner like the Torqbar ( https://www.youtube.com/watch?v=caBEMvndCNY&list=PLLDK6oJjtRB-z-1L3ktLpcljl0EPs4P1-&index=3 ) with a pressed bearing it’ll be fine after a drop, but a Tyzest ( https://www.youtube.com/watch?v=z4rCnU12Dg8&list=PLLDK6oJjtRB-z-1L3ktLpcljl0EPs4P1-&index=24&t=8s ) might not. Not big deal, they are fixable!
This is just a quick fix. I’ll do a video in the future about more permanent solutions if people care. (Please show your care with comments or subs.)
