Re: epon centerpieces

I run my epon centerpieces at 50,000 rpm routinely. Just make sure 
the sectors are filled as closely as possible to the same height so 
you don't bend the center rib between the sectors.

The XL-I interference system doesn't work properly (yet) above 50,000 
anyway - so you should be all set for most everything.
