There's absolutely no play in the bearing. I have shifted the platter several times without any joy and I am wondering if it will become counterproductive to keep taking it on and off. I'll try another platter I think. If anyone is near and has one I can try, I'd appreciate it.

I know it isn't the end of the world, but I'd like to sort it. In the meantime I am going to listen to some loud rock n roll.
