I forget who it was but one of the cabinet bit set companies(I remember they were yellow, at least I think they were) had a video describing them and he installed a fat Oring in the router and dropped the corresponding bits on the oring and thightened there. His were made to swich back and forth from rail to style with out height acdjustment using this oring. He said it doubled as a way to break that lockup.

I've seen that one too- it was the Sommerfeld guy. I haven't tried it yet but it seemed like a solid idea.
