Would anyone know where I might be able to buy some router table insert rings that will fit my Freud aluminum insert? I stopped in the local Woodcraft and looked at the Woodpecker ones they had but they screw on and the Freud insert takes a snap on style. I also called and checked out the Kreg and JessEm rings and they also are the threaded style. Hopefully someone has some first hand experience with something that works with the Freud aluminum insert.
