As mentioned on my Delta TS insert thread, I offered to make up some inserts for my coworker's Grizzly 1023 table saw. Note the little nubs next to the set screws. These are for him to file/sand down for a tighter fit. I may end up adding some to both sides and the front to allow for a more custom fit.
I used the band saw to cut off the top half of the nub on the back, this keeps the back of the plate from lifting when the blade is in contact with it.
