Re: Homemade fidget spinner
That is genius - how do you make it - my 3 kids want one!!!! I have loads of spare chain - what is in the middle / how do the 2 attach to each other!?
Re: Homemade fidget spinner
I think it's a smallest sprocket from a cassette or a small SS ring, then the chain formed around it in such a way that it doesn't want to come off, then joined together
You'll need to clean it first though

It runs around a normal sealed cartridge bearing in the middle - specifically the thin ones that get used inside Hope freehub bodies.
I removed the seals to make sure they ran as smoothly as possible.
The chain was wrapped around the bearing first and held in place with a zip-tie while I glued the chain to the bearing with a hot glue gun, and then removed the zip-tie*
I cut and filed down two road bar end caps to press into the centre of the bearings, filing the rear of them to make sure they didn't catch on the chain.
* turns out the zip-tie adds quite a bit to the integrity of it, as without it, it didn't pass the playground test on the first day
I reglued and left the zip-tie in place and they've been OK. I'm thinking something like araldite might be better then the hot glue gun glue
The circumference of bearing influences the pattern you make with the chain. Here's a singlespeed one I made for myself around a slightly larger bearing:

Re: Homemade fidget spinner
Just throw the chain in some salty water and it will seize in place

Could possibly use a jockey wheel too.
We go out into the hills to lose ourselves, not to get lost. You are only lost if you need to be somewhere else and if you really need to be somewhere else then you're probably in the wrong place to begin with.
