@Cherryville Chuck: No, it was bottoming out on the pillars that the plunge mechanism travels on.
I actually got it figured out. I drilled a hole close to where I was routing and just used my fixed based with a Freud flush trim bit I found in my laminate trimmer that was long enough to JUST get the plate in. I then realized it wasn't deep enough by probably 1/8" so I went ahead and put the original Rockler bit I was going to use in my trim router and took off the template (since I already had the outline shape I wanted on the tabletop) and routed a bit extra out so now its perfect.
I'm now in the process of adding a bunch of coats of polyurethane to harden that surface up a bit (the inner lip) so that when I'm using my leveling screws it doesn't damage it as much as if it was just bare MDF.
That being said, if anyone has any tips on hardening the MDF lip so that the set screws that are used to level the plate don't eat at it as badly I'd greatly like to hear them.
