I've just realised that pritstick glue containers could be used as bearing cleaners. I didn't try fit in a bearing into the thing, or even see if the bearing would fit. If anyone has some, see if the bearing would fit in please!
I don't think the screw in the middle is big so there will be play in the bearings, but with spacers it should be ok...
Can anyone just justify this? I've just been going through this mentally, but it seems pretty possible.
