rmason Posted April 22, 2011 Report Share Posted April 22, 2011 I believe they are for use w/ different diameter bits. Quote Link to comment Share on other sites More sharing options...
Keggers Posted April 22, 2011 Report Share Posted April 22, 2011 RedOak is correct. The different sized holes are for different diameter sized router bits. Use the smallest opening that will work with a particular bit. Quote Link to comment Share on other sites More sharing options...
mikem Posted April 22, 2011 Report Share Posted April 22, 2011 Please note that this is a safety feature of the insert plate. A very dangerous situation can be created if a small piece gets trapped between the opening and the spinning bit. This can easily result in a projectile be shot across the shop, or worse. I am assuming the blank is to allow for a custom made opening, or for closing up the opening if for some reason the table surface is being used for another purpose. 1 Quote Link to comment Share on other sites More sharing options...

PaulMarcel Posted April 23, 2011 Report Share Posted April 23, 2011 Yup, the blank one is for a custom cut; since my router table is in the table saw extension wing, I use the blank to plug the hole. I have a Woodpeckers router plate; very similar to the Incra except the rings lock down differently. You'll notice that they lock when turned counter-clockwise so if a bit nicks them, it moves the ring to tighten, not loosen and fly off (but that's not what Mike was referring to).
