DVD/CD platter widget

I always just put a tiny drop of superglue on the top of the shaft, and then press the turntable back on, having first determined what the correct height setting is, as the turntable tends to grip to the shaft very quickly ... Don't overdo it on the glue though, as you don't want to press any down the shaft and into the top bearing :-\

I tend to find superglue is some sort of super-fluid , almost totally lacking in viscosity and migrates along interference fits rather too easily. As occuring in a laptop drive, the bearing would be only just below the platter.

But can't you buy gel?

You can, yes, but the stuff I use comes on a card of like 12 tubes from the local supermarket, and costs a coupla quid ($3). It works better than all of the named brands, and is reasonably gloopy, whilst still being a good liquid - if you see what I mean ...

To be honest, to be on the safe side, whenever I am glueing anything close to a moving part such as a motor bearing, I tend to put a small amount of oil or grease as appropriate into it. Then, if any superglue does find its way by migration or spillage, it doesn't actually stick to what it shouldn't.

Or just hang it opposite of the pull of gravity while the glue dries :)

Ended up with drop of superglue and capilliary and kept the platter spinning for an hour with a small motor and O ring over plastic drive pulley. Didn't like the idea of playing CD for that time as not sure what vapours would come off in an enclosed space
