I bought a pair of these back in early June, which means I didn't get the extra screws noted in the video.? That's no big deal though.? I used a 1/8" brad point bit followed by a 1/8" router bit (on a router table) to extend my insert for the riving knife.? I might have to extend it a little further though, as there's barely any room to install the riving knife when dealing with a 12" blade.? I haven't had the need to run with my scoring blade lately, so that section is still covered.
I've installed one insert so far, and the only problem I had was that I had to remove a tiny section on the underside near the front in order to get it to fit properly.? It wouldn't seat correctly otherwise as it was pushing against the little bits they have there on the K3.? That was easily done with a beater chisel.? I haven't looked at the other insert to see if it has the same problem.
Separately, I found that I can only remove or install the insert with the sliding table pushed all the way to the rear.? This of course is the opposite of where you put the table when changing the blade.? So if I'm switching out the blade for a dado or for a home-made 45 degree insert then I have to move the table back and forth to go between dealing with the blade and the insert.? That's not the fault of the insert; it's due to the tightness of the space there coupled with the extra "meat" of the insert.? But it's a small inconvenience and easily overlooked thanks to the size and strength of the insert.? I've already broken the little sliver to the left of the blade off an OEM insert; I'll stick with Ramon's inserts from now on.
