I'm with AxlMyk, I tried expanding the screw holes on a couple bases I muckled up (1st 2 clear poly bases with template cutouts) and what happened was that during use pressure and vibration caused the plate to move ever so slightly.
When not using the router with a template guide it wasn't an issue but became one when I did, requiring another reset. I eventually correctly re-cut the holes although I never plugged the bad ones.
Never bite the hand that looks dirty!
