Kind of what I was going to say. Glass is properly flat. Flip the platter over & see if it sits flat without any rocking.Originally Posted by Andre

Thanks everyone;
I still think it is the platter so I will try laying it on glass as suggested but I'm sure it's probably the spindle hole that's not quite right.
Isn't Dave C's new platter still 12 months away?
If I identify the problem I'll come back and let you know!

I think the plinth is a while away, but I thought the platter was iminent!
A good bit of kitchen worktop might be flat enough too

Thought it wasn't due until the end of the year, the platter that is. The plinth is still in the 'giving it a good coat of thinking' stage isn't it?
Hi Les,
Here is a cross-section of the platter, not much to machine here if thats what KAB do.
The metal is only 2.5mm thick and the rubber 4.25mm
Does the taper part of the bearing protrude above the top of the paltter surface?
Get rid of any mats on the platter and then check the undulation.
It has been my observation in talking to many people about bearings and things, that the taper becomes stretched if the platter is continually removed, this maybe your problem
As you can see from the image, the cast aluminium thickness leaves a lot to be desired, compared with somthing nearly 1" thick!! on the shortly to be available new one.

The platter could be quite soon, I'm just waiting for Mike to send me a sample to do some measurements on.

How come we need to play around with mats to damp a "ringing" platter when the current model has rubber damping stuck to it underneath, which my SL150 doesn't have? Ok, ok, record support....
I can't go on and I can't go back, I don't feel so matter of fact,
I tried and tried to make good sense, What's the good to try it all again?

Hi Mike,
Could you resize that picture please? It's WAY WAY too big and knocking the whole page out of sync...
Cheers!
