Tim,

 

I used the factory glass spinner.  Having heard = several stories of this spinner cracking the back plate, I figured it must have = been to a slight out of balance or alignment situation.  Aligning this = spinner is pretty much impossible.  Misalignment will cause a vibration that = leads to failure.
