Ok, time to show my age... go to any hardware store and buy some clear contact paper. Make your cuts and peel it off when you are done. You will most likely need something like Goo Gone to remove any adhesive residue. Easy enough?

Mark, add an auxiliary table top to your router table. 1/2" MDF would be one choice for this. Make whatever size clearance hole you need for your bit and install the bit above your 1-3/16" opening in your table. (Provided your router has the reach and that your collet will fit through the standard PC opening)

If this wont work you could install a mounting plate with removable center rings like the $13 Grizzly T10432047.

Mark, Rockler has always sold blank inserts for their mounting plates. You drill the size opening you need.

Since you require a bearing I am guessing this is for irregular shapes?
