I have a TS2400LS and bought a 8" Dato cutter for it,and HD also had the Blade insert #1030. It said it was for all Rigid Table saws. But the insert does not sit flush even with the set screws all the way down. It is almost .5" short. I noticed on the insert box it was dated 1998. My question is have the revised this part or is there one for the newer saws?
